Phylogeography of cliff racer (Platyceps rhodorachis Jan, 1865) from Punjab, Pakistan

Abstract The present study reports the existence of cliff racer, Platyceps rhodorachis from the plains of Punjab, Pakistan. A total of 10 specimens were captured during the field surveys from June to September, 2018 from different sites of Punjab. Platyceps rhodorachis was identify on the basis of morphology and confirmed through COI gene sequences. The obtained DNA sequences have shown reliable and exact species identification. Newly produced DNA sequences of Platyceps rhodorachis were submitted to GenBank and accession numbers were obtained (MK936174.1, MK941839.1 and MT790210.1). N-J tree based on COI sequences of Platyceps rhodorachis clearly separated as out-group with other members of family Colubridae based on p-distance. The intra-specific genetic variation ranges from 12% to 18%. The DNA sequences of Platyceps rhodorachis kashmirensis, Platyceps rhodorachis ladacensis, Platyceps ventromaculatus, Platyceps ventromaculatus bengalensis and Platyceps ventromaculatus indusai are not available at NCBI to validate their taxonomic positions. In our recommendations, a large scale molecular based identification of Pakistans herpetofauna is required to report more new or subspecies from country.

Mycoplasma spp. in captive snakes (Boa constrictor and Bothrops atrox) from Brazil / Mycoplasma spp. em cobras de cativeiro (Boa constrictor e Bothrops atrox) do Brasil

Although rare, mycoplasmas are included among the causes of respiratory diseases in reptiles and, in the order Squamata, three reports of these microorganisms causing diseases in pythons have already been reported. This study aimed to evaluate the occurrence of Mycoplasma species in captive snakes. A total of 26 snakes of the families Pythonidae (13), Boidae (7), Viperidae (5) and Colubridae (1) from RioZoo, Brazil, were evaluated. Animals were examined to determine clinical signs consistent with any infectious disease. Tracheal swab samples from snakes were collected in Frey medium and analyzed for the presence of Mycoplasma spp.by isolation and a genus-specific PCR. DNA sequencing analyses of six positive samples by PCR were carried out to identify the species. Using isolation 19.23% (5/26) was positive, while 65.38% (17/26) of the animals were positive by PCR. Based on the analyses of the six sequences obtained, there was similarity with a Mycoplasma spp. previously described in a phyton and, M. agassizii and M. testudineum reported in chelonians. This is the first report of Mycoplasma spp. in animals of the families Boidae and Viperidae. Mycoplasma spp. were detected in snakes with and without clinical signs. The mycoplasmas reported resented identity (range, 95% to 100%) to others already described in reptiles. There was no relationship between the presence of Mycoplasma spp. and clinical signs.(AU)

Embora raros, os micoplasmas estão incluídos entre as causas de doenças respiratórias em répteis e, na ordem Squamata, já foram realizados três relatos destes microrganismos causando doença em pítons. Este estudo teve como objetivo avaliar a ocorrência de espécies de Mycoplasma em serpentes em cativeiro. Foram avaliadas 26 serpentes das famílias Pythonidae (13), Boidae (7), Viperidae (5) e Colubridae (1) do RioZoo, Brasil. Os animais foram examinados para determinar sinais clínicos consistentes com qualquer doença infecciosa. Amostras de swab traqueal de cobras foram coletadas em meio Frey e analisadas por isolamento microbiológico e pela técnica da PCR para identificar Mycoplasma spp. As amostras positivas para o gênero Mycoplasma spp. foram submetidas ao sequenciamento genético para identificação das espécies. No isolamento, 19,23% (5/26) foram positivos, enquanto 65,38% (17/26) dos animais foram positivos por PCR. Com base nas análises das seis sequências obtidas, houve similaridade com o Mycoplasma spp. descrito anteriormente em um píton e M. agassizii e M. testudineum encontrados em quelônios. Este é o primeiro relato de Mycoplasma spp. em animais das famílias Boidae e Viperidae. Mycoplasma spp. foi detectado em serpentes com e sem sinais clínicos. Os micoplasmas encontrados apresentaram semelhança genética com outros já descritos em répteis. Não houve relação entre a presença de Mycoplasma spp. e sinais clínicos.(AU)

A new species of burrowing snake (Serpentes: Dipsadidae: Apostolepis ) from the state of Mato Grosso, Central-West region of Brazil

During a faunal rescue conducted at a hydroelectric power station constructed in a Cerrado savanna area in the state of Mato Grosso, a sample of five small stripe-patterned individuals of snakes of the genus Apostolepis Cope, 1862 document the existence of an undescribed species, which is named herein. The new species can be distinguished from its congeners by a combination of scale counts, number of maxillary teeth and color pattern. The new species is most similar to Apostolepis borellii Peracca, 1904, A. lineata Cope, 1887, A. nelsonjorgei Lema & Renner, 2004, A. nigroterminata Boulenger, 1896, A. serrana Lema & Renner, 2006 and A. underwoodi Lema & Campbell, 2017 in its coloration pattern. However, it is distinguished from these species by having a pair of triangular blotches covering portions of the third to sixth supralabials, a white nuchal collar, the shape of the fourth supralabial and the shape of the tip of tail, the number of supralabials in contact with parietals, the size of the anterior chinshields, the color pattern of the paraventral side, parietal and terminal scales, the width of dorsal stripes, and a distinct number of subcaudals. The new species occurs in areas within the Cerrado biome.(AU)

Prenatal development of the sound transmitting apparatus in different embryonic stages of Malpolon monsspesulanus (squamata-serpentes) / Desenvolvimento pré-natal do aparelho transmissor de som em diferentes estágios embrionários de Malpolon monsspesulanus (Squamata-serpentes)

The developmental investigation of sound transmitting apparatus is important in understanding the ontogenetic processes behind morphological diversity. The development of sound conducting apparatus was studied in Montpellier snake; Malpolon monspessulanus at 6.5, 7.2, 8.3 and 9.3 cm total body lengths using light microscopy study. The columella auris firstly appeared as undifferentiated rod shape mesenchymal cells. As the growth proceeded, it chondrified and differentiates into two main parts. In addition, the viscerocranium components which participate in formation of sound transmitting apparatus undergo critical organization. In more advanced stages, procartilagenous stylohyal chondrified and fuse with the well organized quadrate. These data considered as a base for functional and molecular mechanisms of sound transmitting apparatus studies and identification of diseases that may infect them.(AU)

O auris columelar em primeiro lugar apareceu como células mesenquimais forma haste indiferenciada. Como o crescimento passou, ele chondrified e diferencia em duas partes principais. Além disso, os componentes viscerocrânio que participam na formação do aparelho de transmissão de som submeter a organização crítico. Em estágios mais avançados, stylohyal procartilagenous chondrified e se fundem com o quadrado bem organizado. Estes dados considerados como uma base para os mecanismos funcionais e estudos moleculares do aparelho de transmissão de som e identificação de doenças que podem infectar-los.(AU)

Ecology of the snake Atractus paraguayensis (Dipsadidae) in southern Brazil

Knowledge of snake ecology is important to support conservation strategies. Atractus paraguayensis Werner, 1924 is a dipsadidae with semi fossorial habits distributed throughout southern Brazil. We analyzed the morphology, seasonality and reproductive biology of this species in a subtropical area in southern Brazil by combining material from scientific collections and field data. We found that females have a larger body size than males and that the reproductive cycle of females is seasonal, with vitellogenesis occurring in the warmer months of the year. Males exhibited no differences in testicle volume throughout the year; however, mating likely occurs in the spring when males are more active. Recruitment of newborns occurs in late summer. The number of individuals collected during the hottest months (September through February) was significantly higher than the number of individuals collected during the colder months. Our results, which reveal sexual dimorphism in the species and seasonal breeding restricted to warm months, contribute important information about this species biology.

The herpetofauna of the serra do urubu mountain range: a key biodiversity area for conservation in the brazilian atlantic forest

ABSTRACT The Serra do Urubu mountain range is considered a key biodiversity area. It is situated in the Pernambuco Endemism Center, one of the most threatened regions of the Brazilian Atlantic Forest. However, despite the high importance of this area little research on its herpetofauna has been performed. The present study presents an inventory of the herpetofauna of the region, through bibliographic review, searches in museum collections and field expeditions to the RPPNs Frei Caneca and Pedra DAntas, in the municipalities of Jaqueira and Lagoa dos Gatos. The conservation status of the amphibians of the region is discussed. Five expeditions, between 2012 and 2013 were made. The methods employed were visual transect surveys, acoustic census and pitfall traps. We recorded a total of 46 amphibian species, belonging to nine families: Craugastoridae (3 spp.), Bufonidae (3 spp.), Ranidae (1 sp.), Hylidae (25 spp.), Leptodactylidae (8 spp.), Odontophrynidae (1 sp.), Hemiphractidae (2 spp.), Phyllomedusidae (2 spp.) and Microhylidae (1 sp.). We recorded 42 species of squamates: 16 species of lizards families Phyllodactylidae (1 sp.), Gekkonidae (1 sp.), Gymnophthalmidae (1 sp.), Polychrotidae (1 sp.), Leiosauridae (1 sp.), Tropiduridae (3 spp.), Dactyloidae (2 spp.), Diploglossidae (2 spp.), Teiidae (2 spp.), Scincidae (1 sp.), and Iguanidae (1 sp.); and 24 species of snakes: Boidae (3 spp.), Colubridae (2 spp.), Dipsadidae (13 spp.), Elapidae (2 spp.), Typhlopidae (1 sp.), and Viperidae (3 spp.). The occurrence of rare and/or threatened species such as the snakes Dipsas sazimai, Lachesis muta and Sibynomorphus sp. and the amphibians Hylomantis granulosa, Chiasmocleis alagoana, Boana freicanecae and Phyllodytes gyrinaethes reinforces the need for conservation measures at this highly threatened region of the Atlantic Forest.

RESUMO O complexo da Serra do Urubu é considerado uma área chave para a conservação da biodiversidade, estando inserida no Centro de Endemismo de Pernambuco, uma das sub-regiões mais ameaçadas da Mata atlântica brasileira. Porém, apesar da alta importância dessa área, estudos relacionados com a herpetofauna local ainda são escassos. Para a elaboração da lista da herpetofauna da Serra do Urubu, foram feitas consultas na bibliografia, buscas em coleções herpetológicas e expedições de campo para a RPPN de Pedra DAntas e RPPN Frei Caneca, localizadas nos municípios de Jaqueira e Lagoa dos Gatos. Uma discussão sobre o status de conservação dos anfíbios da região também foi realizada. Foram feitas cinco expedições entre os anos de 2012 e 2013, utilizando as metodologias de busca ativa em transectos lineares, censo auditivo e armadilhas de interceptação e queda. No total foram registrados 46 espécies de anfíbios anuros, pertencentes a nove famílias: Craugastoridae (3 spp.), Bufonidae (3 spp.), Ranidae (1 sp.), Hylidae (25 spp.), Leptodactylidae (8 spp.), Odontophrynidae (1 sp.), Hemiphractidae (2 spp.), Phyllomedusidae (2 spp.) e Microhylidae (1 sp.).Com relação aos répteis foram registradas 42 espécies, sendo 16 de lagartos: Phyllodactylidae (1 sp.), Gekkonidae (1 sp.), Gymnophthalmidae (1 sp.), Polychrotidae (1 sp.), Leiosauridae (1 sp.), Tropiduridae (3 spp.), Dactyloidae (2 spp.), Diploglossidae (2 spp.), Teiidae (2 spp.), Scincidae (1 sp.), Iguanidae (1 sp.); e 24 de serpentes: Boidae (3 spp.), Colubridae (2 spp.), Dipsadidae (13 spp.), Elapidae (2 spp.), Typhlopidae (1 sp.), Viperidae (3 spp.).

We recorded 42 species of squamates: 16 species of lizards families Phyllodactylidae (1 sp.), Gekkonidae (1 sp.), Gymnophthalmidae (1 sp.), Polychrotidae (1 sp.), Leiosauridae (1 sp.), Tropiduridae (3 spp.), Dactyloidae (2 spp.), Diploglossidae (2 spp.), Teiidae (2 spp.), Scincidae (1 sp.), and Iguanidae (1 sp.); and 24 species of snakes: Boidae (3 spp.), Colubridae (2 spp.), Dipsadidae (13 spp.), Elapidae (2 spp.), Typhlopidae (1 sp.), and Viperidae (3 spp.). The occurrence of rare and/or threatened species such as the snakes Dipsas sazimai, Lachesis muta and Sibynomorphus sp. and the amphibians Hylomantis granulosa, Chiasmocleis alagoana, Boana freicanecae and Phyllodytes gyrinaethes reinforces the need for conservation measures at this highly threatened region of the Atlantic Forest.(AU)

O complexo da Serra do Urubu é considerado uma área chave para a conservação da biodiversidade, estando inserida no Centro de Endemismo de Pernambuco, uma das subregiões mais ameaçadas da Mata atlântica brasileira. Porém, apesar da alta importância dessa área, estudos relacionados com a herpetofauna local ainda são escassos. Para a elaboração da lista da herpetofauna da Serra do Urubu, foram feitas consultas na bibliografia, buscas em coleções herpetológicas e expedições de campo para a RPPN de Pedra DAntas e RPPN Frei Caneca, localizadas nos municípios de Jaqueira e Lagoa dos Gatos. Uma discussão sobre o status de conservação dos anfíbios da região também foi realizada. Foram feitas cinco expedições entre os anos de 2012 e 2013, utilizando as metodologias de busca ativa em transectos lineares, censo auditivo e armadilhas de interceptação e queda. No total foram registrados 46 espécies de anfíbios anuros, pertencentes a nove famílias: Craugastoridae (3 spp.), Bufonidae (3 spp.), Ranidae (1 sp.), Hylidae (25 spp.), Leptodactylidae (8 spp.), Odontophrynidae (1 sp.), Hemiphractidae (2 spp.), Phyllomedusidae (2 spp.) e Microhylidae (1 sp.).Com relação aos répteis foram registradas 42 espécies, sendo 16 de lagartos: Phyllodactylidae (1 sp.), Gekkonidae (1 sp.), Gymnophthalmidae (1 sp.), Polychrotidae (1 sp.), Leiosauridae (1 sp.), Tropiduridae (3 spp.), Dactyloidae (2 spp.), Diploglossidae (2 spp.), Teiidae (2 spp.), Scincidae (1 sp.), Iguanidae (1 sp.); e 24 de serpentes: Boidae (3 spp.), Colubridae (2 spp.), Dipsadidae (13 spp.), Elapidae (2 spp.), Typhlopidae (1 sp.), Viperidae (3 spp.). Espécies consideradas raras e/ou ameaçadas de extinção como as serpentes Dipsassazimai, Lachesis muta e Sibynomorphussp. e os anfíbios Hylomantis granulosa, Chiasmocleis alagoana, Boana freicanecae e Phyllodytes gyrinaethes,reforçam a necessidade de conservação dessa região de Mata Atlântica extremamente ameaçada.(AU)

Serologic survey for ophidian paramyxovirus in captive snakes / Inquérito sorológico para paramixovirus ofídico em serpentes cativas

The captivity maintenance of snakes is a challenge for the breeders, especially in diseases control. The most common diseases in serpentarium and private collections are the parasites, gastrointestinal problems and respiratory viruses. The biggest concern is the ophidian paramyxovirosis caused by ophidian paramyxovirus (OPMV), which primarily affects the respiratory system and may also involve the nervous system. Often fatal, it was described in Colubridae, Elapidae, Viperidae, Boidae and Pitonidae. This virus is transmitted by aerosols, respiratory secretions, contaminated utensils, ectoparasites such as ticks and digestive excreta. There is no specific treatment or vaccine available. The diagnostic methods are: virus isolation in cell culture; electron microscopy; immunohistochemical; polymerase chain reaction (PCR); hemagglutination-inhibition (HI) and liquid-phase blocking ELISA (Enzyme Linked Immuno Sorbent Assay). This study aimed to make a serological survey, by liquid-phase blocking ELISA, searching to the presence of the anti-OPMV antibodies in 42 snakes (36 poisonous and six, not poisonous) maintained in the Center for the Study of Venoms and Venomous Animals (CEVAP) - UNESP. The serum was collected from caudal ventral vein and sent to the Virology Laboratory of the Biosciences Institute of Botucatu - UNESP for evaluation of antibodies titers.

O manejo de serpentes em cativeiro é um desafio permanente para os criadores, principalmente no que tange ao controle de doenças. Parasitoses, problemas gastrointestinais e viroses respiratórias têm sido as principais enfermidades registradas em serpentários e coleções particulares. A maior preocupação é a paramixovirose ofídica, causada pelo Ophidian paramyxovirus (OPMV), que acomete primariamente o sistema respiratório podendo envolver também o nervoso, sendo muitas vezes fatal e que já foi descrita em colubrídeos, elapídeos, viperídeos, boídeos e pitonídeos. O OPMV é transmitido por aerossóis e pelo contato direto com secreções respiratórias, fômites, ectoparasitas tais como os carrapatos e as excretas digestivas. Não há tratamento específico nem vacinas disponíveis para esta virose. Os procedimentos laboratoriais utilizados para o diagnóstico da infecção incluem: isolamento viral em cultivo celular; microscopia eletrônica; imunoistoquímica; reação em cadeia da polimerase (PCR); ou pode-se ainda trabalhar com a quantificação de anticorpos pelo teste de inibição de hemaglutinação (HI) e pelo teste de ELISA (Enzyme Linked Immuno Sorbent Assay) com bloqueio na fase líquida. O presente estudo empregou a técnica de ELISA com bloqueio de fase líquida para investigar a presença de anticorpos anti-OPMV em 42 serpentes, das quais 36 peçonhentas

Reproduction and diet of Imantodes cenchoa (Dipsadidae: Dipsadinae) from the Brazilian Amazon

Imantodes cenchoa (Linnaeus, 1758) is distributed from the east coast of Mexico to Argentina. In Brazil, it occurs in the north, central-west and northeast regions. We present information on the reproductive biology and diet of I. cenchoa from analysis of 314 specimens deposited in the Herpetological Collection of the Museu Paraense Emílio Goeldi (MPEG). Imantodes cenchoa displays sexual dimorphism in the snout-vent length, where sexually mature females are larger than mature males (t = 4.02, p 0.01; N males = 150, N females = 71), head length (f1.218 = 98.29, p 0.01; N males = 150, N females = 71), and head width (f1.218 = 112.77, p 0.01, N males = 150; N females = 71). Bi-sexual maturity is observed, with males becoming sexually mature earlier than females. Females with eggs were recorded from November to January (rainy season) and from April to July (dry season), suggesting two reproductive peaks throughout the year, with recruitment occurring mainly during the rainy season, when there is a greater supply of food. Imantodes cenchoa is a nocturnal active forager, capturing prey that are asleep on the vegetation. In 32.80% of the analyzed specimens, food contents were present, of which 84.11% were lizards of the genera Norops (69.16%, N = 74) and Gonatodes (14.95%, N = 16). The other 15.89% of the contents were made up of items in an advanced state of digestion, preventing their identification. Some specimens had more than one food item in their digestive tract, accounting for 107 prey items in total. There was no ontogenetic variation in the diet of I. cenchoa, and the predominant direction of prey ingestion was antero-posterior (71.96%). Larger snakes tended to feed on larger prey, although these did not exclude small prey from their diet.

Philodryas chamissonis (Reptilia: Squamata: Colubridae) preys on the arboreal marsupial Dromiciops gliroides (Mammalia: Microbiotheria: Microbiotheriidae) / Philodryas chamissonis (Reptilia: Squamata: Dipsadidae) predando o marsupial arborícola Dromiciops gliroides (Mammalia: Microbiotheria: Microbiotheriidae)

Philodryas chamissonis, the Chilean long-tailed snake, is a diurnal predator mainly of Liolaemus lizards, but also of amphibians, birds, rodents and juvenile rabbits. Dromiciops gliroides (Colocolo opossum) is an arboreal marsupial endemic of temperate rainforest of southern South America. Little information is available about this marsupial's biology and ecology. Here we report the predation of one Colocolo opossum by an adult female P. chamissonis in a mixed Nothofagus forest, composed mainly by N. dombeyi, N. glauca and N. alpina trees, in the "Huemules de Niblinto" National Reserve, Nevados de Chillán, Chile. Since these two species have different activity and habitat use patterns, we discuss how this encounter may have occurred. Although it could just have been an opportunistic event, this finding provides insights into the different components of food chains in forest ecosystems of Chile.(AU)

Philodryas chamissonis, cobra de cauda comprida ("Culebra de cola larga"), é uma cobra diurna, predadora principalmente de lagartos do gênero Liolaemus, mas também de anfíbios, aves, roedores e coelhos jovens. Dromiciops gliroides (colocolo) é um marsupial arborícola endêmico das florestas temperadas do sul da América do Sul. Há pouca informação disponível sobre a biologia e a ecologia deste marsulpial. É reportada, neste estudo, a predação de um colocolo por uma fêmea adulta de P. chamissonis, em uma floresta mista de Nothofagus, composta principalmente por árvores N. dombeyi, N. glauca e N. alpina, na Reserva Nacional de Huemules de Niblinto, Nevados de Chillán, Chile. Uma vez que estas duas espécies possuem diferentes padrões de atividade e de uso de habitat, discute-se como este evento poder ter ocorrido. Embora este possa ter sido apenas um evento oportunístico, o achado fornece novas informações sobre os diferentes componentes da cadeia alimentar nos ecossistemas florestais do Chile.(AU)

Geographical variation in the reproduction and sexual dimorphism of the Boddaert's tropical racer, Mastigodryas boddaerti (Serpentes: Colubridae)

We obtained data on time of sexual maturity, dimorphism, fecundity and on the reproductive cycle of Mastigodryas boddaerti (Sentzen, 1796) through the examination of 321 preserved specimens, of which 221 were collected in the Brazilian Amazon region and 100 in the Cerrado savannas of Central Brazil. The degree of sexual size dimorphism (snout-vent length, SVL) was significantly greater in the specimens from the Cerrado in comparison with those from the Amazon. Females had a significantly larger number of ventral scales, on average, whereas males had more sub-caudal scales. However, there was no intersexual difference in tail length or head width, although the heads of the males were significantly longer, which may reflect dietary differences. Breeding females from the Amazon region contained between one and six eggs (N = 12, mean = 3.0), whereas two females from the Cerrado had four to six eggs (N = 10, mean = 5.0). No relationship was found between the SVL of the Amazonian females and the number of eggs or vitellogenic follicles they contained (Cerrado females were not analyzed here due to small sample size). Males are smaller than their female counterpart when they reach sexual maturity. Even though females from the Amazon reproduce throughout the year, females from the Cerrado breed seasonality.
