Taxonomic re-evaluation of New World Eptesicus and Histiotus (Chiroptera: Vespertilionidae), with the description of a new genus

Eptesicus Rafinesque, 1820 is widely distributed in the Old and New World (26 species), and Histiotus Gervais, 1856 is a South American endemic (11 species). Molecular phylogenies have recovered Eptesicus (sensu lato) as polyphyletic, with New World Eptesicus and the sister genus Histiotus in a paraphyletic American clade sister to Old World Eptesicus. Based on these phylogenetic reconstructions, authors have treated Histiotus as either a subgenus of Eptesicus or restricted Eptesicus to the New World species, treating Histiotus as a full genus, and using the name Cnephaeus Kaup, 1829 at the generic rank to comprise Old World Eptesicus. Based on recently published molecular studies, and on novel qualitative and quantitative morphological comparisons of representatives of Histiotus and New and Old World Eptesicus, we provide evidence for restricting the name Eptesicus to the species E. fuscus (Palisot de Beauvois, 1796) and E. guadeloupensis Genoways & Baker, 1975, allocating the remaining New World species under a new genus, keeping Histiotus as a full genus, and raising Cnephaeus to generic rank to comprise all Old World taxa currently under Eptesicus. This arrangement resolves the paraphyly of New World Eptesicus, and promotes taxonomic stability for Histiotus, which is a well-established genus of easily recognizable Neotropical bats and treated separate from Eptesicus by most authorities.

Did Azara discover Myotis simus or Myotis midastacus (Mammalia: Chiroptera: Vespertilionidae) at least a century before their formal description?

The true identity of the "Chauve-Souris Onzieme ou Chauve-Souris Cannelle" of Azara (1801) and the "LXXXII Murcielago Acanelado" of Azara (1802) has never been clarified. Though it has historically been associated with the Red Myotis, Myotis ruber (É. Geoffroy St.-Hilaire, 1806), there are clear inconsistencies with that species. Unusual features of the description such as the position of the attachment of the wing membrane to the limbs confirm that the species described by Azara belongs to the Myotis simus Thomas, 1901 group. Two members of that group occur in Paraguay, from where Azara described his specimen: Myotis cf. simus and the recently described Myotis midastacus Moratelli & Wilson, 2014. Measurements and collection locality slightly favour its identity as the former, but it is not possible to conclusively state which of these species Azara had in his possession.(AU)

Physiological and biochemical changes induced by Qiangdi nano-863 biological assistant growth apparatus during rice seed priming under temperature stress

Abstract A huge amount of rice cultivation and consumption occur in Asia particularly in Pakistan and China. However, multiple abiotic stresses especially high and low-temperature proved to be a substantial threat for rice production ultimately risks for food security. To overcome various types of abiotic stress; seed priming is among the effective approaches to improve the rice seed germination and growth vigor. Therefore, the present study was planned to evaluate physiological and biochemical modifications in Chinese and Pakistani rice varieties by Qiangdi 863 biological assistant growth apparatus nano treated water (NTW), Osmopriming Calcium chloride (CaCl2), redox priming hydrogen peroxide (H2O2) and hormonal priming by Salicylic acid (SA) under temperature stress conditions. The experiment was performed with completely randomize design conditions. Five rice varieties, nomenclature as Zhongzoa 39, (Chinese rice variety) KSK 133, KS 282, Super basmati and PK 1121 aromatic (Pakistani rice variety) were sown under low temperature (LT) (17ºC), optimal temperature (OT) 27ºC and high temperature (HT) 37ºC conditions. The present study indicated that nanopriming were the most effective treatments increased Germination Energy Percentage (GEP) (96.1, 100, 100%), Speed of Germination (SG) (27.2, 35.45, 37.1), Final Germination Percentage (FGP) (98.2, 99.1, 99.4%), Seedling Dry Weight Biomass (DWB) (0.1, 0.137, 0.14g), Total Chlorophyll Content (0.502, 13.74, 15.21), antioxidant enzymes Superoxide Dismutase (SOD)(3145, 2559, 3345 µg-1FWh-1), Catalase (CAT) (300, 366, 3243 µg-1FWh-1) and decreased Malondialdehyde (MDA) (6.5, 12.2, 6.5 µmol g-1 FW) for Zhongzao 39 and KSK 133 rice varieties under low (LT+NTW), optimal temperature (OP+NTW) and high temperature (HT+NTW) stress., Therefore, nano-priming is recommended to cope with the high and low-temperature stress conditions along with improved productivity of rice.

Resumo Cultivo e consumo de arroz ocorrem em grandes quantidades na Ásia, particularmente no Paquistão e na China. No entanto, vários estresses abióticos, especialmente de alta e baixa temperatura, provaram ser uma ameaça considerável para a produção de arroz, em última análise, riscos para a segurança alimentar. Para superar vários tipos de estresse abiótico, o priming de sementes está entre as abordagens eficazes que melhoram a germinação e o vigor de crescimento das sementes de arroz. Portanto, o presente estudo foi planejado para avaliar as modificações fisiológicas e bioquímicas em variedades de arroz chinês e paquistanês por Qiangdi 863, aparelho assistente biológico de crescimento com água nanotratada (NTW), Osmopriming cloreto de cálcio (CaCl2), peróxido de hidrogênio redox (H2O2) e priming hormonal por ácido salicílico (SA) em condições de estresse de temperatura. O experimento foi realizado em condições de delineamento inteiramente ao acaso. Cinco variedades de arroz, nomenclaturas como Zhongzoa 39 (variedade de arroz chinês), KSK 133, KS 282, Super basmati e PK 1121 aromático (variedade de arroz do Paquistão) foram semeadas sob baixa temperatura (LT) (17 ºC), temperatura ótima (OT) 27 ºC e condições de alta temperatura (HT) 37 ºC. O presente estudo indicou que nanocondicionamento foi o tratamento mais eficaz: aumento da porcentagem de energia de germinação (GEP) (96,1%, 100%, 100%), velocidade de germinação (SG) (27,2, 35,45, 37,1), porcentagem de germinação final (FGP) (98,2%, 99,1%, 99,4%), biomassa de peso seco de mudas (DWB) (0,1 g, 0,137 g, 0,14 g), conteúdo total de clorofila (0,502, 13,74, 15,21), enzimas antioxidantes superóxido dismutase (SOD) (3145, 2559, 3345 µg-1FWh- 1), catalase (CAT) (300, 366, 3243 µg-1FWh-1) e malondialdeído diminuído (MDA) (6,5, 12,2, 6,5 µmol g-1 FW) para as variedades de arroz Zhongzao 39 e KSK 133 sob baixo (LT + NTW), temperatura ótima (OP + NTW) e estresse de alta temperatura (HT + NTW). Portanto, o nanopriming é recomendado para lidar com as condições de estresse de alta e baixa temperatura, juntamente com a produtividade aprimorada do arroz.

A study on the etymology of the scientific names given to planarians (Platyhelminthes, Tricladida) by Ernest Marcus school

Abstract Leading zoologist and taxonomist Ernest Marcus (1893-1968) and his school described numerous new invertebrate taxa, including planarians, or triclads (Platyhelminthes). These authors rarely provided the etymology of names for the new taxa. In this paper, the etymology of 149 names of genera and specific epithets of planarians lacking etymology (or honoring people) is investigated. The etymology of most names was retrieved from original descriptive papers and from Eudóxia Maria Froehlichs recollections, a fellow of Marcus school. It was discovered that the names were usually freely derived from words of the language spoken in the country where the species was found. Some names were motivated by an aspect of the biology of the species. Other names honored people or are arbitrary. The etymology of 19 names could not be retrieved and are only suggested. The origin of another 19 names could not be discovered, nor even their meaning. Knowing the etymology makes it easier to memorize a name and it is a way to preserve the historical and emotional aspects of the authors. Through the retrieved etymologies, the personality of Marcus can also be glimpsed.

Phyllanthus chacoensis (Phyllanthaceae): new record for the Brazilian Amazon and its lectotypification / Phyllanthus chacoensis (Phyllanthaceae): novo registro para a Amazônia brasileira e sua lectotipificação

The first record of Phyllanthus chacoensis for the Brazilian Amazon is presented, based on a specimen from Rondônia state. The species can be recognized by its cauliflorous inflorescence, staminate and pistillate flowers with 4 sepals, devoid of a floral disk, 4 stamens, 2-carpellary ovary, drupaceous, ellipsoidal fruits, with one seed per locule. The species was previously known only from the central-western and northeastern regions of the Caatinga and Pantanal domains in Brazil. We provide a list of synonyms, a detailed description, an updated geographic distribution map in Brazil, data on habitat and conservation status, illustrations of its reproductive characters, and detailed photographs. We also propose a lectotype for the species.(AU)

Notes on Stenhelmoides and description of the true male genitalia of S. strictifrons Grouvelle, 1908 (Coleoptera: Elmidae) / Notas sobre Stenhelmoides e descrição da genitália verdadeira do macho de S. strictifrons Grouvelle, 1908 (Coleoptera: Elmidae)

The genus Stenhelmoides comprises 15 species spread over all Central and South America and its greatest species richness is clearly associated with Amazonian regions. Based on examination of type specimens and additional material, we describe and illustrate the true male genitalia of Stenhelmoides strictifrons, which had until now been incorrectly illustrated in the literature. We also report new records of the genus Stenhelmoides from Brazil and Guyana. In addition to pictures of the species habitus, we provide pictures of the type specimens of Stenhelmoides grandis, S. grouvellei, S. guyanensis; S. strictifrons and S. submaculus. Based on the International Code of Zoological Nomenclature, we recognize additional paralectotypes for S. guyanensis and for S. grouvellei(AU)

Com base no estudo de espécimes-tipo e material adicional, nós descrevemos e ilustramos a genitália verdadeira do macho de Stenhelmoides strictifrons, que, até então, estava representada de maneira equivocada na literatura. Nós também reportamos novos registros de Stenhelmoides para o Brasil e Guiana. Além de imagens do habitus das espécies, fornecemos fotografias dos espécimes-tipo de Stenhelmoides grandis, S. grouvellei, S. guyanensis; S. strictifrons e S. submaculus. De acordo com as regras e recomendações do Código Internacional de Nomenclatura Zoológica, reconhecemos paralectótipos adicionais das espécies S. guyanensis e S. grouvellei(AU)

Ovários policisticos epidermóides e hipoplasia uterina em uma vaca bovina / Epidermoid polycystic ovaries and uterine hypoplasia in a cow

Background: Ovarian cysts originate from mature follicles that do not ovulate within the predicted time according to the oestrous cycle. Dermoid cysts are structures lined by keratinized stratified squamous epithelium, without adjacent epidermal structures, filled by keratinic debris and amorphous proteinaceus material. They are small, located below the cortex, near the hilus. There is controversy regarding the teratogenicity of the dermoid cyst. Some authors use the nomenclature of benign cystic ovarian teratoma, others, reports that although the fibrous wall and histological features are similar to teratomas, it is not associated with this germ cell-derived neoplasia. Case: Ovaries and uterus were received from a female, adult bovine, Nelore, from a slaughterhouse. The left ovary measured 6.5x5.0x3.9 cm and weighed 80 g; the right ovary measured 5.7x3.7x3.0 cm and weighed 60 g. Grossly, the ovaries were similar, presenting floating consistency, multilobulated and pointed aspect, and at the cut surface, there was extravasation of mucopurulent content of whitish colour. Regarding to the uterus, macroscopically, the uterine horns were infantile and decrease in the diameter. Fragments of the tissues were collected and fixed in 10% buffered formalin for histopathological examination and the staining of the slides was done with hematoxylin and eosin. Microscopically, in the ovaries, it was observed rare vestigial elements of ovary identifying an atresic follicle. Polycystic formation with cysts exhibiting partial or total coating of a keratinized squamous epithelium was also observed. In the lumen abundant keratinous material was present. The uterine microscopy revealed compact endometrium with areas variably infiltrated by lymphocytes, plasmocytes and occasional neutrophils. Areas devoid of endometrial glands were observed
