ABSTRACT

We describe a new species of naked-toed gecko of the genus Cyrtopodion Fitzinger, 1843, from the Dahod and Panchmahal districts of Gujarat state, India. The new species is diagnosable by the following suite of characters: a medium-sized Cyrtopodion (adult, snout to vent length up to 50 mm); dorsal scalation on trunk granular, intermixed with enlarged, regularly arranged transverse rows of 15 trihedral tubercles; 6 transverse rows of tubercles on the second segment of the tail; midbody scale rows across belly 20-22; midventral scales 89-97; males with a continuous series of 29-33 precloacal-femoral pores. The new species, Cyrtopodion vindhya sp. nov. is the fifth endemic species of reptile described in the last 15 years from the state of Gujarat that highlights the rich and unique diversity of this understudied region.

ABSTRACT

The colubrid snake genus Dendrelaphis comprises of 45 species (Uetz et al. 2018) of which eleven currently occurs in India (Aengals et al. 2018). A member of this genus, Dendrelaphis caudolineatus (Gray, 1834), was once considered a wide-ranging species in Southeast Asia, the Philippines and the Indo-Australian Archipelago, until Van Rooijen Vogel (2012) resolved taxonomy of this species complex. Now its range is restricted from southern Thailand to Sundaland (Peninsular Malaysia, Sumatra, Billiton and Borneo; presence doubtful in Java of Indonesia) (Van Rooijen Vogel 2012).

ABSTRACT

Hemidactylus Oken, 1817 is one of the most speciose genera of the family Gekkonidae with more than 140 described species (Uetz et al. 2016). While this genus naturally occurs across the tropics and subtropics, a substantial part of its distribution also results from human-mediated dispersal. Carranza Arnold (2006) retrieved five broad clades in a global phylogeny of Hemidactylus, one of which has species distributed in tropical Asia. Subsequent work by Bauer et al. (2010) and Bansal Karanth (2010) revealed that the species from tropical Asia fell into two deeply divergent and potentially non-sister sub-clades-one comprising a large radiation confined to peninsular India and Sri Lanka (the Indian radiation, IR), and the other comprising species largely distributed in Southeast (SE) Asia.

ABSTRACT

A distinctive early Miocene-divergent lineage of Old world racer snakes is described as a new genus and species based on three specimens collected from the western Indian state of Gujarat. Wallaceophis gen. et. gujaratenesis sp. nov. is a members of a clade of old world racers. The monotypic genus represents a distinct lineage among old world racers is recovered as a sister taxa to Lytorhynchus based on ~3047bp of combined nuclear (cmos) and mitochondrial molecular data (cytb, ND4, 12s, 16s). The snake is distinct morphologically in having a unique dorsal scale reduction formula not reported from any known colubrid snake genus. Uncorrected pairwise sequence divergence for nuclear gene cmos between Wallaceophis gen. et. gujaratenesis sp. nov. other members of the clade containing old world racers and whip snake is 21-36%.
