A new species of Dendrelaphis (Serpentes: Colubridae) from Java, Indonesia

A new species of the colubrid snake genus Dendrelaphis Boulenger, 1890, Dendrelaphis underwoodi, new species is described herein. Dendrelaphis underwoodi is endemic to Java, Indonesia. Univariate and multivariate analyses of the differences between D. underwoodi and the congeneric taxa D. cyanochloris (Wall, 1921), D. formosus (Boie, 1827), D. humayuni Tiwara & Biswas, 1973, D. kopsteini Vogel & Van Rooijen, 2007, and D. pictus (Gmelin, 1789) demonstrate that D. underwoodi constitutes a distinct insular lineage. The available data on the three known specimens suggest that D. underwoodi is an inhabitant of hilly or mountainous habitat. An updated key tot the Dendrelaphis species of the Sunda region is provided.
