Phylogeny, biogeography, and character evolution of the genus Sophora s.l. (Fabaceae, Papilionoideae).

The papilionoid legume genus Sophora (Fabaceae) exhibits a worldwide distribution, but a phylogenetic framework to understand the evolution of this group is lacking to date. Previous studies have demonstrated that Sophora is not monophyletic and might include Ammodendron, Ammothamnus, and Echinosophora, but the relationships among these four genera (defined as Sophora s.l.) are unclear. Here we used a nuclear DNA dataset (ETS, ITS, SQD1) and a plastid DNA dataset (matK, rbcL, rpl32-trnL, trnL-F) of 654 accession sequences to reconstruct the phylogenetic relationships, estimate the divergence times and ancestral range of Sophora s.l., and infer the evolution of chromosome number and morphological characteristics. Our major aim was to reconstruct phylogenetic relationships to test monophyly and elucidate relationships within the genus. Our results indicated that Ammodendron, Ammothamnus, and Echinosophora are embedded within Sophora s.s. and that nine well-supported clades can be recognized within comprise Sophora s.l. Ancestral character state estimation revealed that the most recent common ancestor of Sophora s.l. was a deciduous shrub that lacks rhizome spines and has unwinged legumes. Divergence times estimation and ancestral area reconstruction showed that Sophora s.l. originated in Central Asia and/or adjacent Southeast China in the early Oligocene (ca. 31 Mya) and dispersed from these regions into East and South Asia's adjacent areas and North America via the Bering land bridge. The analyses also supported a South American origin for S. sect. Edwardsia, which experienced rapid radiation with its major lineages diversifying over a relatively narrow timescale (8 Mya).

Association Between MTHFR C677T Polymorphism and Congenital Heart Disease.

Many published studies have evaluated the association between the 5,10-methylenetetrahydrofolate reductase (MTHFR) C677T (rs1801133) polymorphism and the risk of congenital heart disease (CHD); however, the specific conclusion is still controversial.To get a more accurate conclusion, we used a meta-analysis to evaluate the association between the MTHFR gene C677T polymorphism and the risk of CHD.Based on the design-based search strategy, a comprehensive literature search was conducted on PubMed, OVID, Cochrane Library, Embase, Wanfang, CNKI, and Web of Science. We selected the Newcastle-Ottawa Scale (NOS) to assess the quality of the included studies. We performed a heterogeneity test on the results of the study and calculated the combined odds ratios (ORs) and its corresponding 95% confidence intervals (95% CIs) under a random- or fixed-effect model. Subgroup analyses were conducted by ethnicity, source of controls, sample size, and genotyping method. Sensitivity analysis was used to insure authenticity of this meta-analysis result. Egger's test and Begg's funnel plot were performed to detect publication bias.Eventually, our meta-analysis included 15 eligible studies. We observed a significant correlation between the MTHFR C677T polymorphism and the development of CHD in the recessive model (OR: 1.35, 95% CI: 1.06-1.71, P = 0.006) for the overall population. In subgroups stratified by ethnicity and source of controls, subgroup analyses indicated similar associations in Asians and hospital-based groups, but not for Caucasians and population-based groups. Egger's test and Begg's funnel plot demonstrated no significant publication bias in our study.Our analysis identified that MTHFR C677T allele is a risk genetic for CHD development, especially in Asians compared with Caucasians.

Increased urinary adiponectin level is associated with contrast-induced nephropathy in patients undergoing elective percutaneous coronary intervention.

BACKGROUND: Contrast-induced nephropathy (CIN) is one of major and serious complications in patients undergoing percutaneous coronary intervention (PCI). It is unknown whether increased urinary adiponectin (UAPN), a sensitive marker for early renal function impairment, is associated with an increased risk of CIN. Therefore, we prospectively investigate the association of UAPN with CIN. METHODS: We prospectively enrolled 208 patients who were undergoing elective PCI. The baseline UAPN was assessed prior to PCI. The ROC analysis was used to evaluate the predictive value of UAPN for CIN. Multivariate logistic regression analysis was performed to analyze the independent risk factors for CIN. RESULTS: Of 208 patients, CIN occurred in 19 patients (9.13%), and 6 of them (2.88%) required dialysis. Patients with CIN had a higher UAPN level than those without CIN (17.15 ± 12.36 vs. 10.29 ± 3.04 ng/ml, P < 0.01). ROC analysis showed that the optimal cutoff value of UAPN for predicting CIN was 12.24 ng/ml with 68.42% sensitivity and 76.72% specificity (AUC = 0.7204; 95% CI, 0.582-0.859; 푃< 0.01). Multivariate analysis demonstrated that UAPN (OR, 5.071; 95% CI,1.711-15.028; P < 0.01) and serum creatinine (Scr) > 124 µmol/L (OR, 4.210; 95% CI, 1.297-13.669; P < 0.01) were independently associated with CIN. CONCLUSIONS: Our present study showed that a higher baseline UAPN (≥12.24 ng/ml) level was significantly associated with an increased risk for developing CIN post PCI.

Identification of flavonoids in Dendrobium huoshanense and comparison with those in allied species of Dendrobium by TLC, HPLC and HPLC coupled with electrospray ionization multi-stage tandem MS analyses.

Dendrobium huoshanense, a unique species in the genus Orchidaceae, is only found in China and is known as "mihu". Due to the lack of quality control, the use of D. huoshanense in the herbal market has been limited. In this study, methods based on thin-layer chromatography, high-performance liquid chromatography and high-performance liquid chromatography coupled with electrospray ionization multi-stage tandem mass spectrometry were used to identify the flavonoids in D. huoshanense and distinguish this species from other Dendrobium species. Using thin-layer chromatography, a characteristic band was observed for D. huoshanense, and this band was absent from the thin-layer chromatography plates of other Dendrobium species. Then, using high-performance liquid chromatography, nine peaks of flavonoids were observed in the chromatograms of ten batches of D. huoshanense. Ultimately, 22 flavonoids in D. huoshanense were identified by multi-stage tandem mass spectrometry, and 11 of these compounds are being reported from D. huoshanense for the first time. In addition, two compounds both with molecular weights of 710, were identified as being unique to D. huoshanense; one of these compounds, apigenin-6-C-α-L-rhamnosyl-(1→2)-ß-D-glucoside-8-C-α-L-arabinoside, was proven to be responsible for the characteristic thin-layer chromatography band of D. huoshanense. These analysis methods can be applied for the identification and quality control of D. Huoshanense.

Role of Endothelial Nitric Oxide Synthase Polymorphisms in Atrial Fibrillation: A PRISMA-Compliant Meta-Analysis.

BACKGROUND Research interest in endothelial nitric oxide synthase(eNOS) polymorphisms and atrial fibrillation (AF) has grown in last recent years, but the results of individual studies are inconsistent due to their small sample sizes. MATERIAL AND METHODS We searched databases for eligible studies on eNOS and AF, extracted the relevant data, and rigorously screened them according to inclusion and exclusion criteria. Then, we evaluated the study quality according to the Newcastle-Ottawa scale score, and we pooled the odds ratios (ORs) and 95% confidence intervals (CIs) by using a random-effects model or fixed-effects model based on inter-study heterogeneity. In addition, we performed subgroup analysis and sensitivity analysis and assessed publication bias. RESULTS According to the inclusion and exclusion criteria, we finally found 8 studies in this search. The recessive (OR=0.81; 95% CI=0.67 to 0.97; p=0.988; I²=0.0%) model showed that the eNOS 786T/C polymorphism was relevant to AF. We also found that the eNOS 786T/C polymorphism decreases the risk of AF, especially in white people (OR=0.81; 95% CI=0.67 to 0.97; P=0.023 for recessive model) and in the control population (OR=0.79; 95% CI=0.65 to 0.97; P=0.022 for recessive model). We found no obvious publication bias. CONCLUSIONS The eNOS gene loci 786T/C polymorphism is relevant to the risk of AF. Our results suggest that the 786T/C polymorphism significantly decreases AF risks in white people and control populations. Larger studies are required for further evaluation.

[Clinical Characteristics of Autoimmune Disease with Dual Seropositive Antibodies of Leucine-rich Glioma Inactivated 1 and Contactin-associated Protein 2].

Objective To explore the clinical characteristics of autoimmune disease with dual seropositive antibodies of leucine-rich glioma inactivated 1(LGI1)and contactin-associated protein 2(Caspr2).Methods The clinical data of seven patients with dual seropositive LGI1 and Caspr2 antibodies who were admitted to the Neurology Department of Peking Union Medical College Hospital from July 2014 to December 2017 were retrospectively analyzed.Results Central,peripheral and autonomic nervous systems were all involved in the seven cases;100%(7/7)presented with insomnia,myokymia,neuropahic pain and hyperhydrosis;71%(5/7)showed memory decline or psychiatric and behavioral symptoms;57%(4/7)had urinary hesitation or constipation;and 43%(3/7)had seizure.Electromyography showed 100%(6/6) of the patients had prolonged afterdischarges following normal M waves and/or abnormal spontaneous firing.Electroencephalography revealed slow waves or basic rhythm slowing in 71%(5/7)of patients.Electrocardiography showed sinus tachycardia,axis deviation,and prolonged QT intervals in 71%(5/7)of patients.One patient died from arrhythmia before immunotherapy.One died from pulmonary infection after immunotherapy.Improvement with immunotherapy was documented in the other five cases.No relapse was noted during the 1-2-year follow-up.Conclusions Autoimmune disease with dual seropositive antibodies of LGI1 and Caspr2 can diffusely affect the central,peripheral,and autonomic nervous systems.The possibility of this disease should be considered in patients with acute and subacute onset of neuropsychiatric symptoms,especially in patients with accompanying insomnia,myokymia,and hyperhydrosis.

Identification and detection sensitivity of Microcystis aeruginosa from mixed and field samples using MALDI-TOF MS.

To verify the applicability of identifying Microcystis aeruginosa by matrix-assisted laser desorption-ionization-time-of-flight mass spectrometry (MALDI-TOF MS), mixed and field samples were employed to study the sensitivity and the analysis power, respectively. Series diluted samples and artificially mixed samples by the M. aeruginosa NIES-843 strain were designed to verify the sensitivity. The lowest detection limit was 1.955 × 106 cells in pure samples, while for mixed samples, the lowest detection limit and ratio of NIES-843 strain were 2.88 × 106 cells and 33.7%, respectively. The results provided a reference for the reasonable volume of the water sample in which the M. aeruginosa could be detected. Ribosomal protein biomarkers for identifying M. aeruginosa which were successfully detected from the field samples in Taihu Lake, indicated that the identification of M. aeruginosa by MALDI-TOF MS could be applied in field samples. Furthermore, different genetic types of M. aeruginosa strains were also detected at different locations in Taihu Lake, which revealed the diversity of M. aeruginosa and the detection power of MALDI-TOF MS at the strain level for the field samples. The sensitivity and detection power in the analysis of M. aeruginosa by the MALDI-TOF MS demonstrated the applicability of this method in routine environmental monitoring.

Statistical properties of the rovibrational bound levels for Ar2Kr.

We calculate the rovibrational bound levels with total angular momentum J = 0, 1 of 40Ar284Kr trimer using the slow variable discretization method combined with the finite-element method-discrete variable representation basis. The statistical distributions of the rovibrational levels for JΠ=0e, 1e, and 1o symmetries are presented and the effects of the Axilrod-Teller potential term are considered. For the 0e and 1e symmetries, the Axilrod-Teller term makes the spectra become fully chaotic. However, for the 1o symmetry, statistical properties depend mainly on the coupling between K = 0 and K = 1 and the Axilrod-Teller term has a small effect.

δ-catenin promotes the malignant phenotype in breast cancer.

δ-Catenin is a member of the p120 catenin family. Similar to p120ctn, δ-catenin contains nine central Armadillo repeats and binds to the juxtamembrane domain (JMD) of E-cadherin. We used immunohistochemistry to detect δ-catenin expression in breast carcinoma (128 cases), and δ-catenin mRNA and protein expression was detected by reverse transcription-polymerase chain reaction and Western blotting (45 cases). The effects of δ-catenin on the activity of small GTPases and the biological behavior of breast cancer cells were explored by pulldown, flow cytometry, methyl thiazolyl tetrazolium, and Matrigel invasion assays. The results showed that δ-catenin expression increased in breast cancer tissues and was associated with a higher degree of malignancy (invasive lobular breast cancer, high tumor-node-metastasis stage, lymph node metastasis, and C-erbB-2+) and poor prognosis. Postoperative survival was shorter in patients with δ-catenin-positive expression than in patients with negative expression. δ-Catenin may regulate Cdc42/Rac1 activity, promote proliferation and invasion of breast cancer cells, and alter cell cycle progression. We conclude that δ-catenin tends to overexpress in breast carcinoma and promotes the malignant phenotype.

[Correlation of Allelopathy of Rehmannia glutinosa Root Exudates and Their Phenolic Acids Contents].

OBJECTIVE: To study the allelopathic potential of Rehmannia glutinosa root exudates in different growth stages and dynamic change of phenolic acids contents, in order to reveal the correlation between phenolic acids and allelbpathy effect of Rehmannia glutinosa. METHODS: Root exudates of Rehmannia glutinosa in different growth stages were obtained by a new instrument which was used to collect the root exudates of xerophytes. After that, bioassay was applied to estimate allelopathy effect of the root exudates. HPLC was used to determine the contents of five phenolic acids (coumaric acid, 4-hydroxybenzoic acid, vanillic acid, syringic acid and ferulic acid) which were reported to relate to allelopathy effect. Correlation of bioassay data and HPLC data were also analyzed. RESULTS: The germination rate of radish after soaking by root exudates of different growth stages of Rehmannia glutinosa was 97. 89%, 92. 38%, 89. 52%, 85. 71%, 85. 71%, 84. 76% and 83. 81%, respectively, which indicated a decline trend. And significant differences were shown from previous enlargement stage compared with the contrast. The bud length after soaking by root exudates was 5. 68, 5. 76, 5. 91, 5. 65, 5. 41, 5. 28 and 5. 11 cm, separately, which increased slightly before decreasing gradually. Previous enlargement stage was also the initial period when significant differences were shown. Five phenolic acids were detected in root exudates by HPLC, while the change of their contents and the allelopathy effect of root exudates did not perform a similar trend. Correlation analysis indicated the five phenolic acids did not have significant relevance (r = - 0. 666 - 0. 590) with germination rate and bud length of radish except the negative correlation (r = -0. 833, P <0. 05) of syringic acid and bud length. CONCLUSION: Significant allelopathy effect of Rehmannia glutinosa is performed from previous enlargement stage and enhanced with its growth. Syringic acid is a probable dominant allelochemical of Rehmannia glutinosa.

[Advances in studies on growth metabolism and response mechanisms of medicinal plants under drought stress].

Drought stress exerts a considerable effect on growth, physiology and secondary metabolisms of the medicinal plants. It could inhabit the growth of the medicinal plants but promote secretion of secondary metabolites. Other researches indicated that the medicinal plants could depend on the ABA signaling pathway and secreting osmotic substances to resist the drought stress and reduce the damage by it. The article concludes the changes in growth, physiology, secondary metabolisms and response mechanisms of medicinal plants to drought stress that provides a theoretical basis for exploring the relationship between medicinal plants and drought stress.

[Genetic diversity of different populations of lilyturf revealed by RSAP analysis].

Restriction site amplification polymorphism (RSAP) markers were employed to access the genetic diversity and relationship of 120 lilyturf germplasms from different geographical origins. Sixteen RSAP primer pairs generated 326 polymorphic bands, of which 318 (97.55%) were polymorphic. The value of polymorphism information content (PIC) ranged from 0.87 to 0.95 with an average of 0.92. These results indicated there was abundant genetic diversity among samples. The results of data analysis on 20 population showed that the value of percentage of polymorphic locus (PPL), Nei's gene diversity (H) and Shannon's information index (I) were 19.94%-85.58%, 0.082 6-0.210 7, 0.120 6-0.328 1 respectively. The most abundant genetic diversity was found in the O. japonicus population from Zhejiang and the least in the Liriope minor population. The genetic distance among 20 population was 0.024 6-0.286 8, of which the minimum genetic distance was 0.024 6 between population I and population 13 while the maximum 0.286 8 between population 5 and population 15. Coefficient of genetic differentiation among natural populations was 0.115 3 (Gst). And the gene differentiation contributed to 43.07% of the total genetic variation among populations and to 56.93% within populations. The total gene flow (Nm) was 0.660 9. UPMGA clustering analysis was basically similar to of the principle coordinate analysis (PCA). The 120 samples were classified into four major groups, which were basically corresponded with the genetic relationships based on morphological traits. The results of UPMGA and PCA were also consistent with geographical origins.

Overexpression of small GTPases directly correlates with expression of δ-catenin and their coexpression predicts a poor clinical outcome in nonsmall cell lung cancer.

δ-catenin can affect cytoskeletal assembly, and promote cell migration by regulating the activity of small GTPases. While many malignancies have been shown to be positive for δ-catenin, it is still unclear whether δ-catenin and small GTPases are coexpressed in tumor cells, and so is the relationship between their coexpression and prognosis in the tumor patients. In this study, immunohistochemistry was performed to examine expressive levels of δ-catenin, cdc42, and Rac1 in 135 cases of nonsmall cell lung cancer (NSCLC), including 60 cases with follow-up records. Thirty samples of paired lung cancer tissues and adjacent normal lung tissues were collected to analyze mRNA and protein expression of δ-catenin and small GTPases. The effects of δ-catenin on small GTPases expression and invasive ability of lung cancer cells were also evaluated. Compared with normal lung tissues, both mRNA and protein levels of δ-catenin and small GTPases were increased in lung cancer tissues (P < 0.05), and the expression of small GTPases directly correlated with that of δ-catenin (P < 0.001). In addition, δ-catenin and small GTPases tended to be coexpressed in lung adenocarcinoma, advanced stages, and primary tumors with lymph node metastasis (all P < 0.05). The patients with coexpression of δ-catenin and small GTPases had a shorter survival time than those without coexpression (P < 0.05). Furthermore, δ-catenin overexpression could enhance invasive ability of lung cancer cells by upregulating protein and transcriptional level of small GTPases. Therefore, δ-catenin likely upregulates the activity of small GTPases at transcriptional level, and their coexpression may predict a poor clinical outcome in NSCLC patients.

Oreocharis oriolus, a new species of Gesneriaceae in a sclerophyllous oak community from Yunnan, Southwest China.

Oreocharis oriolus, a new species of Gesneriaceae in a sclerophyllous oak community from Yunnan, Southwest China, is described and illustrated. Morphologically, it resembles both O. forrestii and O. georgei, while it is distinct in combined characters of wrinkled leaves, peduncle and pedicel covered with whitish and egladular villous hairs, bract lanceolate and nearly glabrescent adaxially, and staminode absent. Molecular phylogenetic analysis based on nuclear ribosomal internal transcribed spacer (nrITS) and chloroplast DNA fragment (trnL-F) of 61 congeneric species also supported O. oriolus as a new species while it was nested with O. delavayi. It was currently assessed as 'Critically Endangered' (CR) regarding to its small-sized population and narrow distribution following the IUCN categories and criteria.

Thrixspermumtaeniophyllum (Orchidaceae, Epidendroideae), a new species from southwest China, based on molecular and morphological evidence.

Thrixspermumtaeniophyllum is described as a new orchid species from Wenchuan County, Sichuan Province of southwest China. It is morphologically similar to T.japonicum, but it differs from the latter in having branched stems, slightly fleshy strap-shaped leaves, longer inflorescences with 3-6 flowers and a capitate gynandrium with a lip-shaped mouth opening. Its species status is also supported by molecular phylogenetic analyses, based on nuclear ribosome internal transcribed spacer (nrITS) and three chloroplast DNA fragments (matK, psbA-trnH and trnL-F), which showed distinct systematic boundaries from the most morphologically similar T.japonicum and their morphological relatives T.saruwatarii and T.pygmaeum.

Molecule characterization of chemosensory and metabolism-related genes in the proboscis of Athetis lepigone.

Introduction: The moth species Athetis lepigone (Möschler) (Lepidoptera: Noctuidae), which has recently been identified as a pest of summer maize (Zea mays L.) in China, has demonstrated a rapid proliferation with in the Huang-Huai-Hai Plain region since its initial discovery in Hebei Province in 2005. It has become a prevalent pest of corn crops, and its ability to adapt quickly to its surroundings is currently being investigated. One of the key characteristics of its siphoning mouthparts is not only the feeding apparatus itself but also the chemosensory organs that enable the detection of chemical signals from the surrounding environment. However, there is a lack of comprehensive research on the genes responsible for chemosensory and metabolic mechanisms in the proboscises of male and female A. lepigone adults. Methods: In this study, we utilized transcriptome analysis to identify a total of fifty chemosensory genes from six distinct families, including 19 odorant-binding proteins (OBPs), 22 chemosensory proteins (CSPs), one co-receptor (Orco), six odorant receptors (ORs), four ionotropic receptors (IRs), and two sensory neuron membrane proteins (SNMPs) in the proboscis. Notably, seven OBPs, two CSPs, and one OR were discovered for the first time. Additionally, fourteen genes related to metabolism, including cytochrome P450 (CYPs) and carboxylesterases (CXEs), were also identified. Furthermore, a qualitative analysis was conducted on the relative transcript levels of eight related genes. The expression of 21 annotated chemosensory and metabolic genes was compared between A. lepigone adults and larvae using qRT-PCR, revealing tissue specificity. The majority of genes exhibited predominant expression in the antennae and proboscis during the adult stage, while showing slight expression in the combination of sixth-instar larval head oral appendages (maxilla, labium, and antenna) and pheromone gland-ovipositors of female adults. Results/discussion: Our study points to a new pest control strategies that these newly discovered genes have the potential to serve as targets for enhancing future pest control, including mating disruption and the use of food attractants. And it would be advantageous to ascertain the distribution of chemosensory gene expression and gain insights into the functionalities of these genes, thereby establishing a novel theoretical framework for the advancement of eco-friendly pesticides and efficient pest management strategies in the future.

Endoscopic surgery of cavernous sinus tumors originating from the extradura.

In the present study, we explored the effects of various endoscopic approaches in patients with cavernous sinus (CS) tumors. Five endoscopic approaches, including the endoscopic transseptal transsphenoidal approach, extended endoscopic transseptal transsphenoidal approach, extended transnasal transmaxillary approach, extranasal extended maxillary sinus approach, and endoscopic transnasal transpterygoid approach, were selected for the resection of CS tumors from 36 patients. Thirty gross total tumors and 6 subtotal tumors were removed. After a follow-up period of 6 months to 3 years, 30 patients were determined to be recurrence-free, and 2 patients had unchanged residual tumors. One patient with a recurrent pituitary adenoma underwent a second surgery, and 1 patient with chordoma died because of an intracavernous carotid artery rupture 18 months after the operation. Various endoscopic approaches tailored to the origin and extent of the CS tumor were proven efficacious for the maximal and precise removal of CS tumors while avoiding vital structures.

Pollen morphology of the genus Sophora (Fabaceae) and its taxonomic implications.

The genus Sophora (Fabaceae) is one of the taxonomically challenging genera with high economic and medical values. In this study, the pollen morphology of 43 samples of 27 species, 4 subspecies, and 4 varieties of the genus Sophora and 3 closely related genera was examined using scanning electron microscopy to evaluate the pollen diversity of the genus and its taxonomic significance. Pollen grains of the studied species were tricolporate (rarely six-aperture), and pollen shape varied from suboblate, spheroidal, subprolate to prolate. Echinate external ornamentation was reported for the first time in some species of the genus. Aperture membrane ornamentation and outline in a polar/equatorial view were described for the first time in the genus. Principal component analysis was used to understand the relationship and discrimination between the species and the genera, with six components accounting for 79.92% of the total variance. Taxonomic keys based on pollen morphology were also constructed to easily identify the taxa of the genus through palynological characteristics. Results showed that pollen morphology alone is not sufficient to elucidate or reconstruct taxonomic relationships within the genus Sophora, but palynological assessments can provide some useful information for identifying taxonomically problematic taxa.

Euonymusaquifolium (Celastraceae): Rediscovered in flowering with respect to its taxonomy, nomenclature, and rarity.

A small population of Euonymusaquifolium (Celastraceae) with flowering plants was discovered more than 100 kilometers away from its type locality. The incomplete original description of this species is supplemented here with floral materials since it is known from only two gatherings of fruiting specimens. Its 5-merous flowers and two ovules per locule support its position in Euonymus, and this inference is further reinforced by phylogenetic analysis based on the nuclear internal transcribed spacer (ITS) of rDNA. The specific epithet has long been treated as "aquifolius" to agree with the generic gender of Euonymus. But after examination of the protologues of this and other related species described simultaneously by the same authors, as well as their handwritten annotations attached on the type specimens, we conclude that the epithet aquifolium was used as a noun and it should be retained unchanged. Despite this newly discovered population some 100 kilometers away from its type locality, this species is still assessed as Critical Endangered (CR) according to the IUCN Red List Categories and Criteria.
