Recently Described Snakes
Two interesting snakes have been described recently in Zootaxa.
The first is a new species of false water cobra, called Hydrodynastes melanogigas. (At present, I've only seen the abstract, not the full paper.) From the abstract:
"A new species of Hydrodynastes is described from the State of Tocantins, Central Brazil. The new species is distinguished from all congeners by having a melanistic color pattern, with head and dorsum of the body mostly dark-brown to black; absence of postocular stripe; venter grayish-brown, with dark rounded blotches outlining two lateral stripes which become gradually paler towards the posterior region of the belly, disappearing after midbody."
The second is a species of Pseudoboa, a group of nocturnal prey-constricting colubrids. Pseudoboa martinsi is a "brightly colored species" in the Amazon basin of Brazil. (abstract)
