Description of Hydrodynastes melanogigas


Franco et al. (2007) describe a new species of Hydrodynastes  from the state of Tocantins, Central Brazil. The new species differs from H. gigas and H. bicinctus primarily through its melanism, the lack of a postocular stripe and ventral coloration. Like the other species of the genus, it is a large (~2 metres), semi-aquatic snake.
