RESUMO

Leptodiranycthemera Werner, 1901, was described from a specimen collected in Ecuador. No information on the holotype was published after its description. In the most recent review of Leptodeira, Leptodiranycthemera was considered to be a synonym of Leptodeiraannulataannulata, although the author emphasized that the holotype was lost and did not include the pholidotic data from the original description in his account of Leptodeiraannulataannulata. Since this review, a number of authors have accepted this synonymy. Recently, analyzing specimens of Leptodeira in the Museum für Naturkunde, Berlin, Germany, we discovered the holotype of Leptodiranycthemera. This holotype is re-described here, and its correct identity is determined. Based on the analysis of meristic characters and the color of the holotype, we recognize Leptodiranycthemera as a junior synonym of Oxyrhopuspetolarius.

RESUMO

Elapotinus picteti Jan, 1862 is an enigmatic snake taxon that has been described without locality data. Genus and species, both based on the unique holotype, were considered to belong to the venomous African Aparallactinae for more than a century, but although this taxon was never rediscovered it was accepted as a valid species until present. To clarify the taxonomic status of E. picteti its characters were compared with literature and determination keys for the whole world. This literature survey and the subsequent study of type specimens revealed that the monotypic Elapotinus is a subjective senior synonym of the monotypic Malagasy pseudoxyrhophiine snake genus Exallodontophis Cadle, 1999 which is characterized by its unique aglyphous dentition. We therefore transfer Elapotinus from the lamprophiid subfamily Aparallactinae to the subfamily Pseudoxyrhophiinae. Furthermore, Elapotinus picteti strongly resembles the Malagasy species Exallodontophis albignaci (Domergue, 1984) in external morphology, coloration and dentition. As a consequence we consider Elapotinus picteti a subjective senior synonym of Exallodontophis albignaci.

RESUMO

Herpetological surveys in the dry forests of the limestone massif Montagne des Français in the far north of Madagascar have recently yielded a number of undescribed reptile species. Here we describe an additional new and potentially microendemic species of the snake genus Madagascarophis (Squamata: Serpentes: Pseudoxyrhophiinae) which lives in this massif syntopically with M. colubrinus septentrionalis and differs distinctly from M. colubrinus and M. meridionalis in its mitochondrial and nuclear DNA sequences. Morphologically Madagascarophis fuchsi sp. nov. is characterized by a broad contact between the posterior inframaxillaries (genials), 25 dorsal scale rows at midbody, and a low number of ventrals (171-172). We redescribe the holotype of M. ocellatus and present new data on the morphological variation of the northern subspecies M. c. septentrionalis and M. c. citrinus. Although Montagne des Français has recently been included into the network of nature reserves in Madagascar, continuous deforestation is strongly threatening this important center of reptile endemism. In line with the assessment of other microendemic reptiles of this massif we suggest to consider the new species as Critically Endangered according to the IUCN criteria and encourage new efforts to protect this area more efficiently.
