On the identity of Chironius flavolineatus (Serpentes: Colubridae).
The snake genus Chironius Fitzinger, 1826 is endemic to the Neotropical region, occurring from Honduras to Uruguay and northeastern Argentina. Some species of the genus have taxonomic and/or nomenclatural problems, such as C. flavolineatus which lacks agreement in the literature about its authorship and type locality. Some researchers have been suggesting Jan (1863) as the author of the species...
متن کاملTaxonomic revision of Chironius flavolineatus (Jan, 1863) with description of a new species (Serpentes: Colubridae).
We conducted a taxonomic review of Chironius flavolineatus on the basis of continuous and discrete morphological characters. We recognize a new species which is distinguished from all currently recognized congeners by the following unique combination of characters: first third of body black or dark gray; vertebral stripe yellowish or creamish white distinct from dorsals of nape and extending th...
متن کاملComplex evolution in the Neotropics: the origin and diversification of the widespread genus Leptodeira (Serpentes: Colubridae).
Lineage diversification in the Neotropics is an interesting topic in evolutionary biology but is also one of the least understood. The abiotic and biotic complexity of the region precludes generalizations that can be drawn regarding the historical evolutionary processes responsible for the diversity observed. The snake genus Leptodeira provides an excellent opportunity to investigate such proce...
متن کاملA new species of the Southeast Asian genus Opisthotropis (Serpentes: Colubridae: Natricinae) from western Hunan, China
A new species of natricine snake of the Southeast Asian genus Opisthotropis Gü nther, 1872 is described from western Hunan Province of China based on both mitochondrial DNA and morphological data. The new species is morphologically most similar and genetically most closely related to O. cheni Zhao, 1999 and O. latouchii (Boulenger, 1899), but possesses considerable genetic divergence (p-distanc...
متن کاملTaxonomic revision of Drymoluber Amaral, 1930 (Serpentes: Colubridae).
The present study is a taxonomic revision of the genus Drymoluber Amaral, 1930, using meristic and morphometric characters, aspects of external hemipenial morphology and body coloration. Sexual dimorphism occurs in D. dichrous and D. brazili but was not detected in D. apurimacensis. Morphological variation within D. dichrous is related to geographic distance between populations. Furthermore, va...
