Lycodon mackinnoni is a poorly known Himalayan endemic snake known from Western Himalaya. Since the original description of L. mackinnoni almost 112 years ago, this species was not reported from its type locality and its phylogenetic position remain unknown. We herein, provide detail morphological description, comparison with type material, phylogenetic relationship with its congeners and new natural history information.

We report the rediscovery of Oligodon melaneus 112 years after its original description and document the third, and only non-type, specimen for the species. The new specimen was found 267 km east of the type locality (Tindharia, West Bengal state) from Assam state, India. We designate a lectotype for the species, and provide an extended description of a freshly collected male specimen. Phylogenetic analyses of 16s and cytb mitochondrial genes provide support for O. melaneus being closely related to the widespread South Asian endemic O. arnensis.

Redescription and geographic distribution of Raorchestes shillongensis (Anura: Rhacophoridae) from Meghalaya, Northeast India. Raorchestes shillongensis is a threatened rhacophorid frog endemic to Northeast India. The species is poorly known and systematic information is lacking. We redescribe here the morphology of the species from topotypic material and compare with other Bush Frogs of the region. The locality records from the state of Meghalaya are new. We describe its advertisement call and discuss its phylogenetic position.Keywords: advertisement call, conservation, morphology, phylogeny, Rhacophorinae. ResumoRedescrição e distribuição geográfica de Raorchestes shillongensis (Anura: Rhacophoridae) de Meghalaya, nordeste da Índia. Raorchestes shillongensis é um anuro racoforídeo ameaçado e endêmico do nordeste da Índia. A espécie é pouco conhecida, não havendo informação sistemática. Redescrevemos aqui a morfologia da espécie a partir de material topotípico e a comparamos com outros racoforídeos da região. O registro da localidade no estado de Meghalaya é novo. Descrevemos ainda seu canto nupcial e discutimos sua posição filogenética.

A new species of natricine snake of the genus Rhabdophis is described from Northeast India. Morphologically the new species is similar to Rhabdophis himalayanus but it can be distinguished from it by lacking a nuchal groove and nuchal glands, being relatively smaller, and having a distinct neck, ventral, and subcaudal coloration. In overall coloration it resembles R. chrysargos, from which it is distinguished by several aspects of its morphology and genetic differences. The discovery of Rhabdophis bindi sp. nov. reveals that forested regions in the northeastern part of India needs further biological exploration.
