Abstract
The second known specimen of Perulibatrachus aquilonarius from India is compared to the holotype and new information on fresh color is presented. A mitochondrial COI barcode also was generated for the specimen. The genus Perulibatrachus is representedby four species (Greenfield et al, 2008). One of these, P. aquilonarius Greenfield, was described from a single specimen collected by A.W.C.T. Herre in 1941 in India (Greenfield, 2005). The specimen had been misidentified as Chatrabus damaranus and deposited in the ichthyological collections of Stanford University, and later was transferred to the California Academy pf Sciences. Because of the age of the specimen, its color pattern was badly faded. In February 2010 the first author collected the secondknown specimen of P. aquilonarius from off Tuticorin, India and was able to photograph its fresh coloration. The species is rede-scribed here.
