Leposoma percarinatum is one of the two recognized parthenogenetic species in the lizard family Gymnophthalmidae, and only females have been reported to date. Here we report and describe the first known males attributed to the species from two localities of north- western Amazonia. We compare the morphological variation (15 meristic and 10 discrete characters, all relevant to species identification in Leposoma) of males and females from these populations with that of specimens from unisexual populations to test the hypothesis that they belong to the same species. We did not find significant morphological differences between unisexual and bisexual populations, except for those associated with sexual dimorphism. Additionally, we reviewed literature dealing with the origin of parthenogenesis in L. percarinatum and we provide some insights into this subject, in view of the discovery of males in this species. Keywords. Amazonia; Hybridization; Lizards; Unisexuality. Resumo. Leposoma percarinatum é uma das duas espécies de lagartos partenogenéticas da familia Gymnophthalmidae, onde apenas fêmeas são conhecidas até o momento. Neste artigo reportamos e descrevemos os primeiros machos encontrados da espécie, pertencentes a duas populações no noroeste da América do Sul. Com o intuito de testar a hipótese de que os machos encontrados pertencem à espécie L. perca‑ rinatum, comparamos a variação morfológica (15 caracteres merísticos e 10 categóricos, todos relevantes para a identificação de espécies do gênero Leposoma) encontrada em machos e fêmeas das duas populações bissexuais com exemplares de populações unissexuais ao longo da Amazônia. Não encontramos diferenças significativas na morfologia entre populações uni e bissexuais, a não ser aquelas decorrentes de dimorfismo sexual tradicionalmente conhecidas em lagartos. Adicionalmente, revisamos a literatura referente à origem da partenogênese em L. percarinatum e fornecemos algumas reflexões sobre este tópico, fruto do aparecimento de machos na espécie.

  • Density, Population Size, and Habitat Use by Ameivula Nativo (Teiidae) in a Remnant of Atlantic Forest in Brazil

Bairro Maracanã, 20550-013 Rio de Janeiro, Rio de Janeiro, Brazil 1Corresponding author: [email protected] Abstract.—We estimated the population density, size, occupancy, and detectability of the lizard Ameivula nativo (no English common name), an endemic and endangered species, in one of the largest remnants of the Atlantic Forest in Espirito Santo, Brazil, by using methods that consider imperfect detectability. We used linear transect surveys to estimate density and abundance. We also used transect data to estimate large and small-scale species occupancy using six covariates (sampled region, the proportion of exposed soil, the proportion of shrub cover, the proportion of herbaceous cover, air temperature, and relative humidity). The estimated overall density for A. nativo in the Vale Natural Reserve (VNR) was 11.03 ± 2.07 (standard error) individuals/ha with an estimated population size of 7,258 ± 1,365 individuals. At large scales, A. nativo occupancy probability was influenced by region, and local scale occupancy was influenced by proportion of exposed soil. Detectability was affected only by the air temperature, which may be a result of the species physiology because it is an active forager.

  • Xenosaurus Tzacualtipantecus. the Zacualtipán Knob-Scaled Lizard Is Endemic to the Sierra Madre Oriental of Eastern Mexico
    Xenosaurus tzacualtipantecus. The Zacualtipán knob-scaled lizard is endemic to the Sierra Madre Oriental of eastern Mexico. This medium-large lizard (female holotype measures 188 mm in total length) is known only from the vicinity of the type locality in eastern Hidalgo, at an elevation of 1,900 m in pine-oak forest, and a nearby locality at 2,000 m in northern Veracruz (Woolrich- Piña and Smith 2012). Xenosaurus tzacualtipantecus is thought to belong to the northern clade of the genus, which also contains X. newmanorum and X. platyceps (Bhullar 2011). As with its congeners, X. tzacualtipantecus is an inhabitant of crevices in limestone rocks. This species consumes beetles and lepidopteran larvae and gives birth to living young. The habitat of this lizard in the vicinity of the type locality is being deforested, and people in nearby towns have created an open garbage dump in this area. We determined its EVS as 17, in the middle of the high vulnerability category (see text for explanation), and its status by the IUCN and SEMAR- NAT presently are undetermined. This newly described endemic species is one of nine known species in the monogeneric family Xenosauridae, which is endemic to northern Mesoamerica (Mexico from Tamaulipas to Chiapas and into the montane portions of Alta Verapaz, Guatemala). All but one of these nine species is endemic to Mexico.

Only one species, the nematode Spauligodon saxicolae (Pharyngodonidae), was found. The extremely low infection and diversity parameters, falling among the lowest within the Pal- aearctic saurians, support depauperate helminth communities for these parthenogenetic lacertid lizards. Our results suggest that parthenogenetic Darevskia follow a pattern of parasitism similar to other unisexual lizards (i.e. Aspidocelis). The low rates of infection and diversity may be explained by the decreasing opportunities for interchanging helminths rather than factors of susceptibility of unisexual hosts.

A new cryptic species of lizard (Sauria: Teiidae: Gymnophthalmus) from Venezuela. Zool. Med. Leiden 66 (1), 31.vii. 1992:1-18, figs. 1-7, tables 1-2.— ISSN 0024-0672. Key words: Gymnophthalmus; Teiidae; biogeography; Guianan Region; Venezuela. Gymnophthalmus cryptus spec. nov. is described and illustrated on the basis of males and females collected in the Territorio Federal Amazonas, southern Venezuela. Some details on ecology and distri• bution are also presented. The females of G. cryptus are very similar to the unisexual Gymnophthalmus underwoodi, which also occurs in the Guianan Region. In fact, G. cryptus is one of the best candidates for future genetic research to determine whether it is the missing ancestor of G. underwoodi, a parthenogenetic species of hybrid origin (G. speciosus x G. spec.?). Two other series of previously unre• ported species of Gymnophthalmus from Venezuela are also discussed. Marinus S.
