RESUMO

The goal of this study was to evaluate P450 aromatase localization in the epididymis of two different vertebrates: the lizard Podarcis sicula, a seasonal breeder, and Rattus rattus, a continuous breeder. P450 aromatase is a key enzyme involved in the local control of spermatogenesis and steroidogenesis and we proved for the first time that this enzyme is represented in the epididymis of both P. sicula and R. rattus. In details, P450 aromatase was well represented in epithelial and myoid cells and in the connective tissue of P. sicula epididymis during the reproductive period; instead, during autumnal resumption this enzyme was absent in the connective tissue. During the non-reproductive period, P450 aromatase was localized only in myoid cells of P. sicula epididymis, whereas in R. rattus it was localized both in myoid cells and connective tissue. Our findings, the first on the epididymis aromatase localization in the vertebrates, suggest a possible role of P450 aromatase in the control of male genital tract function, particularly in sperm maturation.

RESUMO

A classic question in evolutionary biology is whether behavioral flexibility hastens or hinders evolutionary change. The latter idea, that behavior reduces the number of environmental states experienced by an organism and buffers that organism against selection, has been dubbed the "Bogert Effect" after Charles Bogert, the biologist who first popularized the phenomenon using data from lizards. The Bogert Effect is pervasive when traits like body temperature, which tend to be invariant across space in species that behaviorally thermoregulate, are considered. Nevertheless, behavioral thermoregulation decreases or stops when spatial variation in operative temperature is low. We compared environmental temperatures, thermoregulatory behavior, and a suite of physiological and morphological traits between two populations of the southern rock agama (Agama atra) in South Africa that experience different climatic regimes. Individuals from both populations thermoregulated efficiently, maintaining body temperatures within their preferred temperature range throughout most of their activity cycle. Nevertheless, they differed in the thermal sensitivity of resting metabolic rate at cooler body temperatures and in morphology. Our results support the common assertion that thermoregulatory behavior may prevent divergence in traits like field-active body temperature, which are measured during periods of high environmental heterogeneity. Nevertheless, we show that other traits may be free to diverge if they are under selection during times when environments are homogenous. We argue that the importance of the Bogert Effect is critically dependent on the nature of environmental heterogeneity and will therefore be relevant to some traits and irrelevant to others in many populations.

RESUMO

Several factors influence the dynamics and structure of parasite communities. Our goal was to investigate how the community composition, prevalence and abundance of parasites change across seven populations of the exotic lizard Hemidactylus mabouia in Northeast Brazil, and to describe ontogenetic and sex variations. We found differences in the composition of component communities and patterns of infection according to the host body size across the lizard populations. We did not find any variation between the sexes regarding epidemiological patterns, which can probably be explained by the similar diet and habitat use of male and female H. mabouia. An unusually high abundance and prevalence of trematodes infecting this host lizard was apparent when we compared other native lizard hosts, and we suggest that local environmental conditions might be advantageous to the development and life cycle of these parasites due to the abundance of all the intermediate and definitive hosts.

RESUMO

Liolaemus is one of the most diverse genus of lizards in the world (Esquerré et al. 2013), with 257 species listed in the last review focusing on its diversity (Abdala Quinteros 2014). Certain species within this genus, especially the earlier ones, were described in very little detail, even lacking an appropriate description of the holotype and/or type locality. This has created uncertainties in the taxonomic identity of several Liolaemus species (Espinoza et al. 2011; Quinteros et al. 2008; Troncoso-Palacios Garin 2013; Langstroth 2011).

RESUMO

The genus Japalura Gray, 1853 s. l. currently comprises 34 species (Japalura n=7; Cristidorsa Wang, Deepak, Datta-Roy, Lin, Jiang, Che Siler, 2018, n=2; Diploderma Hallowell, 1861, n=25). Furthermore the species Diploderma polygonatum is composed of its nominate form and three additional subspecies. For all but one species primary types (holo-, syn- or lectotypes) are available, and in most cases paratypical specimens have also been deposited. The type specimen of Japalura yunnannensis appears to be lost.

RESUMO

A new species of gecko, Lygodactylus tsavoensis sp. nov., is described from Tsavo Conservation Area in southeastern Kenya. It is a member of the Lygodactylus picturatus group and is distinguished from other closely related species by its small size (maximum 35 mm SVL), five postpostmental scales, seven precloacal pores, and a distinctive color pattern. A pale Y-shaped mark on the crown continues along the vertebral midline to the tail base and is flanked by a pair of dark stripes. In addition to its morphological differences, the new species is genetically divergent from its most closely related congeners, L. keniensis and L. wojnowskii. The new species is widespread in the southern and southeastern arid lands within the Tsavo Conservation Area, mainly in Taita-Taveta, Kitui, Makueni, Kajiado, Kilifi, Kwale and Tana River Counties. It is chiefly associated with bushland with short trees, including areas of anthropogenic influence.

RESUMO

An integrative taxonomic analysis of Subdoluseps herberti from southern Thailand and Peninsular Malaysia and S. samajaya from Sarawak, East Malaysia (Borneo) recovers the former as paraphyletic with respect to the latter. The analyses recover the three southernmost populations of S. herberti in Peninsular Malaysia as conspecific and the sister lineage of S. samajaya, whereas S. herberti from Thailand and northern Peninsular Malaysia constitute the sister species to S. samajaya plus the southern three Peninsular Malaysian populations. As such, the southern populations are described herein as S. malayana sp. nov. and all three species are referred to as the S. herberti group. Clade boundaries and breaks within this group on the Thai-Malay Peninsula occurring at the Isthmus of Kra, across the Kangar-Pattani line, and between the Thai-Malay Peninsula and Borneo are consistent with phylogeographic patterns of other Sundaic taxa. The discovery of S. malayana sp. nov. continues to underscore the fact that, despite the well-studied nature of the lizard fauna of Peninsular Malaysia, much of it still remains unrealized and for conservation efforts to move forward, field research followed by expeditiously revised taxonomies must continue.

RESUMO

We present a preliminary ND2 phylogeny of South Asian Cnemaspis, recovering a number of deeply divergent clades within Indian Cnemaspis, endemic to the southern and northern Western Ghats besides the Mysore Plateau and hills of Tamil Nadu. There are a number of unnamed lineages that are >5% divergent on ND2 across the phylogeny, including three from the gracilis clade on an elevation gradient (800-1400 m asl.) around Yercaud in the Shevaroy massif, Salem district, Tamil Nadu. We describe two of these as new species- Cnemaspis shevaroyensis sp. nov. and Cnemaspis thackerayi sp. nov. are both allied to Cnemaspis gracilis and can be diagnosed from all other Indian Cnemaspis by the absence of spine-like scales on flank, heterogeneous dorsal pholidosis, presence of femoral and precloacal pores, tail with enlarged, strongly keeled, conical tubercles forming whorls, a median row of enlarged and smooth sub-caudals. They differ from C. gracilis and each other in body size, the number of tubercles around midbody, the number of tubercles in paravertebral rows, the number of femoral and precloacal pores, the number of poreless scales in-between precloacal pores and between femoral and precloacal pores, and subtle colour pattern differences; besides uncorrected mitochondrial sequence divergence (7.9-16.6 %). We also provide a description of Cnemaspis yercaudensis from its type locality and an additional locality. The discovery of two endemic species and a third unnamed divergent lineage from an isolated massif in peninsular India outside the Western Ghats indicate that many other such understudied hill ranges may harbour high endemic biodiversity.

RESUMO

We describe the new species Norops arenal sp. nov. from Parque Nacional Volcán Arenal, north-central Costa Rica. In external morphology and genetic similarity of the 16S DNA barcode, Norops arenal is most similar to N. altae, N. fortunensis, N. fuscoauratus, N. gruuo, N. kemptoni, N. monteverde, N. pseudokemptoni, and N. tenorioensis. In morphology it shares with these species the following characteristics: (1) short hind limbs; (2) a single elongate prenasal scale; (3) tiny, smooth, often juxtaposed body scales; and (4) a slender habitus, often delicate. Norops arenal differs from these species, among several scalation details, by having a blackish central area in the male dewlap in life and in preservative (vs. no suffusion of black pigment on male dewlap in the other species), and a small red female dewlap in life (vs. dirty white, cream colored, or orange); extremely short hind legs with the tip of fourth toe of the adpressed hind leg reaching only to level of shoulder (vs. usually at least to level of ear in the other species); a short tail with a tail length/SVL ratio of 1.53 in single specimen with complete tail (vs. this ratio >1.6 in the other species); and a tiny size with 41.5 mm in single known adult male and 38.5 mm in single known adult female (vs. SVL of adults usually >42.0 mm). It further differs from N. altae, N. fuscoauratus, N. gruuo, N. pseudokemptoni, and N. tenorioensis by having a unilobed hemipenis (vs. bilobed in these five species).

RESUMO

We describe a new species of rock gecko of the genus Cnemaspis from Java, Indonesia, representing the first record of the genus for this Island. The new species was collected from the southern slopes of Gunung Muria, a dormant volcano in Central Java. The new species is easily distinguished from all congeners by having a maximum SVL of 58.1 mm in males and 56.9 mm in females; a pair of sharp conical tubercle clusters on the occiput; a warty bridge on the nuchal loop, extending from the upper tympanum and curving to the nape; dorsal tubercles not linearly arranged; 18-20 paravertebral tubercles; postmentals separated by one scale; gular, pectoral and abdominal scales, ventral scales of fore- and hindlimbs, and subcaudal scales keeled; no tubercles on lower flank; precloacal and femoral pores absent; enlarged submetacarpal scales present on the first digit of the manus; 38-40 ventral scales; 31-35 lamellae under fourth toe; two postcloacal tubercles on each side; enlarged median subcaudal scales row present; caudal tubercles encircling tail; and a sexually dimorphic ventral color pattern, with males having a yellow belly and females white and the ventral surface of the tail in males yellow proximally changing to white at mid-length, whereas in females, alternating black and white rings completely encircle the tail, which is black distally.

RESUMO

The phylogeny of the mite genus Pterygosoma Peters, 1849 (Acariformes: Pterygosomatidae), permanent parasites of lizards of the families Agamidae, Gerrhosauridae and Liolaemidae (Reptilia: Squamata), was inferred with maximum parsimony, successive weighting and implied weighting approaches based on 182 characters of 48 ingroup and 12 outgroup species. All undertaken analyses questioned the monophyly of the genus. Based on this research, Pterygosoma includes 56 mite species associated with agamas from Africa and Asia (Sauria: Agamidae). Within the genus seven natural species groups were found: mutabilis, inermis, melanum, caucasica, fimbriata, singularis and foliosetis; 13 species of the genus were not assigned to any of the groups due to their unique morphological characters. For the ligare group of the subgenus Pterygosoma s. str. (7 species) associated with the South American tree lizards from the family Liolaemidae, a new genus, Neopterygosoma gen. nov., is established. The subgenus Gerrhosaurobia Lawrence, 1959 (3 species) associated with the African plated lizards of the family Gerrhosauridae is elevated to the genus rank. Diagnoses for the three genera are presented. Historical associations are reconstructed by fitting the obtained mite tree into the host topology on the family level. Results of coevolutionary analysis highlight the coincidence of both trees. The studies suggest that the ancestor of the genus Pterygosoma switched from the hosts of Gerrhosaurobia i.e. from the plated lizards (Gerrhosauridae) to the agamas (Agamidae), and the genus Pterygosoma has its biogeographic origin in North Africa, and colonized Asia via the Arabian Peninsula, which is congruent with the historical biogeography of its hosts.

RESUMO

We describe a new species of Cyrtodactylus from Karkar Island, an active volcano off the northern coast of New Guinea. It is a member of the C. sermowaiensis species group, which is defined by the absence of enlarged precloacal and femoral scales and the absence of precloacal/femoral pores in males. This species group includes two other species, one of which is widespread along the northern mountain ranges of New Guinea, and the other of which is restricted to Manus Island. The new species differs from each of these in its larger size; more-tuberculate dorsum; wide, even bands across the dorsum; and uniformly brown crown of the head. Distributional data suggest that the C. sermowaiensis species group originated on the former islands of the South Caroline Arc, although only C. sermowaiensis currently occupies terranes derived from that arc. The other two species are now restricted to volcanic islands that originated independent of that arc, but the current restriction of our new species to Karkar Island seems likely to be a relictual distribution of a formerly wider range. The status of Karkar as an active volcano, and the explosive sterilization or virtual disappearance of other islands in the Bismarck Volcanic Arc, suggest that the new species could be at threat of immediate extinction should a similar explosive eruption occur on Karkar.

RESUMO

We describe a new species of rock-dwelling Gehyra Gray, 1834 (Gekkonidae) from the Einasleigh Uplands of inland north Queensland, Australia. Morphological, ecological, and molecular data clearly support the new species as distinct and place it within the 'australis group'. Gehyra electrum sp. nov. is distinguished from congeners by a combination of medium adult size (SVL 46-50 mm), an orange-brown to pinkish-orange background colouration with a pattern of distinct whitish spots and irregular black to purple-brown blotches or bars, possessing 7-8 undivided subdigital lamellae on the expanded portion of the fourth toe, and a wedge-shaped mental scale that separates the inner-postmental scales along 40% or more of their length. Gehyra electrum sp. nov. is a rock specialist currently known only from granite outcrops of the Mt Surprise region, Queensland. This is the second recently described Gehyra from the Einasleigh Uplands and adds to the growing number of endemic reptiles recognised in the region.

RESUMO

The forest-dwelling skinks of the Oligosoma oliveri ('marbled skink') species-complex, from the North Island of New Zealand, have proven difficult taxonomically because all mainland populations are extinct, obscuring patterns of distribution and population interaction. Twenty-four small insular populations have survived off the north-east coast of the North Island, which are at present classified into three species. In this paper I re-assess the available phenotypic, ecological, biogeographic and phylogenetic evidence associated with these skinks. As a result, O. pachysomaticum (Robb) is raised from synonymy with O. oliveri (McCann) and more precise historical distribution limits are inferred for each member of the group. Implications for the conservation management of each species are also discussed.

RESUMO

The monotypic genus Dravidogecko, represented by its type-species D. anamallensis, is singular amongst peninsular Indian gekkonid lineages in its endemism to the Western Ghats. Molecular species delimitation approaches reveal at least seven species-level lineages within the genus from its distribution range across the mid-high elevations of the southern Western Ghats of India. These lineages, albeit superficially cryptic, are patently diagnosable from each other by employing a limited but precise set of morphological characters. Six of these lineages that were obscured under the nomen D. anamallensis are herein recognized as distinct species. A reappraisal of the genus Dravidogecko is provided based on external morphology and osteological characters, along with a detailed redescription of the holotype of D. anamallensis. A key to the species based on diagnostic characters is presented. Gene-trees based on mitochondrial and nuclear DNA data recovered marginally disparate topologies and were consequently coalesced into a species-tree for phylogenetic inference. Timetree analysis reveals late Miocene cladogenesis in this group and establishes late Palaeocene divergence from its sister genus, Hemidactylus, making Dravidogecko one of the earliest, extant lizard lineages to have colonized peninsular India.

RESUMO

The diffusion of "citizen science" brings considerable benefits to ecological research (Bonney et al. 2009; Dickinson et al. 2012) and involves an increasing use of data provided by "non-professionals" for the establishment of distribution atlases (for instance, through online platforms such as "iNaturalist"). Therefore, it is important that the presented data are sufficiently reliable and, for this reason, photographic documentation of what has been observed is always encouraged. In many cases, however, the circumstances or the conditions of the observed organism do not allow a photographic identification. Dichotomous keys are tools that, in addition to the use by technicians, researchers and students, can be useful to "non-professional" observers to improve the accuracy in the determination of observations to be submitted to the scientific community. This also applies to the herpetological field, and thus to this work, which offers an updated dichotomous key for the determination of Italian snakes (the first since the one published in Corti et al. (2011)) in light of the various systematic updates that affected this taxon.

RESUMO

The montane agamid lizard genus Oriocalotes is currently considered monotypic, represented by the species, O. paulus. The systematic status of this taxon has remained questionable since its initial descriptions in the mid-1800s. A detailed molecular and morphological study was carried out to assess the validity of this genus, and its systematic position within the Asian agamid subfamily, Draconinae. Freshly collected and historical museum specimens from the type locality of O. paulus were examined morphologically, along with additional samples collected from localities in Mizoram state, Northeast India. Utilising newly generated molecular sequences (two mitochondrial and three nuclear genes), combined with those previously published for representative genera from the subfamilies Draconinae and Agaminae, Maximum Likelihood and Bayesian phylogenetic trees were constructed. Phylogenetic results suggest that Oriocalotes is part of the widespread South and Southeast Asian radiation of Calotes. Comparative morphological studies (including external morphology, hemipenis and osteology) between Oriocalotes and related genera further support this systematic placement. Oriocalotes is herein regarded as a junior subjective synonym of Calotes. Calotes paulus comb. nov. is also assigned a lectotype and given a detailed redescription based on the lectotype, paralectotypes and additional topotypic material. Furthermore, the specimens collected from Mizoram populations are found to be morphologically and genetically distinct from Calotes paulus comb. nov., and are described herein as a new species, Calotes zolaiking sp. nov.

RESUMO

An integrative taxonomic analysis of the Ptychozoon lionotum group across its range in Indochina and Sundaland recovers P. lionotum sensu lato Annandale, 1905 as paraphyletic with respect to P. popaense Grismer, Wood, Thura, Grismer, Brown, Stuart, 2018a and composed of four allopatric, genetically divergent, ND2 mitochondrial lineages. Multivariate and univariate analyses of continuous and discrete morphological and color pattern characters statistically and discretely diagnose each lineage from one another and together, with maximum likelihood and Bayesian inference analyses, provide the foundation for the recognition of each lineage as a new species-hypotheses corroborated with a Generalized Mixed Yule Coalescent species delimitation analysis. Ptychozoon cicakterbang sp. nov. ranges throughout Peninsular Malaysia to Pulau Natuna Besar, Indonesia; P. kabkaebin sp. nov. is endemic to northern and central Laos; and P. tokehos sp. nov. ranges from southern Thailand south of the Isthmus of Kra northward to Chiang Mai, fringing the Chao Phraya Basin and ranging southward through Cambodia to southern Vietnam. Ptychozoon lionotum sensu stricto ranges from northwestern Laos through southern Myanmar to eastern India. The phylogeographic structure within each species varies considerably with P. lionotum s.s. showing no genetic divergence across its 1,100 km range compared to P. cicakterbang sp. nov. showing upwards of 8.2% sequence divergence between syntopic individuals. Significant phylogeographic structure exists within P. tokehos sp. nov. and increased sampling throughout Thailand may require additional taxonomic changes within this species.

RESUMO

Mexico contains a large number of amphibian and reptile species, and the states in the southeastern part of the country are the richest and most diverse. Although the study of species richness within Mexico's individual states has been increasing over the last two decades, herpetofaunal species lists for several states in the central region are incomplete. Herein, we provide a list of the herpetofauna of the state of Querétaro, a state that remains relatively unexplored. We also indicate the conservation status of the component species in the state, based on the national and international categorizations, as well as their Environmental Vulnerability Scores (EVS). Based on a review of literature and specimens in scientific collections, our results show that the herpetofauna of Querétaro currently is composed of 138 species, of which 34 are amphibians (27 anurans and seven caudates) and 104 are reptiles (three turtles, 34 lizards, and 67 snakes). The number of Mexican endemic species occurring in the state consists of 19 amphibians and 50 reptiles, representing 55.9% and 48.1%, respectively, of the total numbers in these groups. A total of 61 species (13 species of amphibians and 48 of reptiles) are listed in NOM-059-SEMARNAT-2010, within the categories of Special Protection (Pr) and Threatened (A). According to the International Union for Conservation of Nature (IUCN 2019), 34 species of amphibians (100% of species) and 87 species of reptiles (83.65% of a total of 104) have been placed within a risk category, i.e., except for the DD and NE categories. The EVS results show that nine species of amphibians have high environmental vulnerability, 11 species medium vulnerability, and 14 low vulnerability, whereas among the reptiles, 22 species have high vulnerability, 43 medium vulnerability, and 37 species low vulnerability. The herpetofauna of Querétaro illustrates a high level of species richness, which is typical of central Mexico, as well as diverse groupings associated with the arid, temperate, and tropical environments found in the state. These types of studies are necessary for increasing our knowledge of the herpetofauna in the various states of Mexico, as well as for evaluating the conservation status and implementing management plans for species in both herpetofaunal groups.

RESUMO

Several recent papers have reviewed the life and work of French herpetologist Louis Amédée Lantz. They have detailed the composition of his collections deposited in several museums. However, since then, several other important specimens from his collections deposited at the Natural History Museum (NHM, UK) have come to light and we here present all of them in detail. We discovered paralectotypes of Lacerta saxicola obscura Lantz Cyrén (BMNH 1918.11.21.5-7), syntypes of Lacerta boemica Sukhov (BMNH 1960.1.4.26-30, BMNH 1965.337-342) and Lacerta viridis media Lantz Cyrén (BMNH 1960.1.4.25, 1966.512). We also identified numerous specimens from the French Mediterranean islands in Lantz's collection deposited at the NHM, some of which represent the first reported specimens of their species from certain islands. We here provide data on all these specimens. We also place the Mediterranean island specimens from the Lantz collection in their historical context and emphasize the historical and taxonomic value of these collections.
