Large frog, females 48.8-110mm SVL, males 25-59.7mm SVL (Narayan et al. 2008). Discs of fingers are small, only slightly larger than toe discs. Maxillary and vomerine teeth present. Colour variable, dorsal surface varies from light brown, reddish brown, greenish brown to dark brown. There is usually an X marking on the shoulders, nearly always a white spot on each shoulder, and if no white spot, a white vertebral stripe running the length of the body. Ventral surface whitish sometimes with traces of brown. Hind limbs have dark crossbars. Males lack nuptial pads.
Taxonomy: Many people have noticed that the spelling of this taxon has changed from Platymantis vitianus to P. vitiana. Here are some comments on this subject by David Wake: "The species described by Dumeril in 1853 as Hylodes vitianus is a valid species, but through the course of time it has been shifted about taxonomically from Hylodes to Platymantis by Gunther in 1858. Linguistic analysis has since revealed that there is a gender error in Latin syntax. The species name does not agree with the generic name, necessitating a change to vitiana. It is unclear exactly who made this spelling change but it was not AWeb. Frost 1985 uses vitianus but in his current on-line Amphibian Species of the World (Feb 2006) he uses vitiana and so I believe it is Frost who has made the change. At AmphibiaWeb we generally defer to Frost who is very careful to get his Latin right."
