Abstract
Philautus hoffmanni is considered the sister species of P. asankai. According to published literature the dorsal color of P. hoffmanni is usually pale green with reddish brown, ash and brown spots. White coloration in these frogs has not been reported previously even P. asankai shows ashy white. This white coloration of P. hoffmanni highlights again the close relation of this species with P. asankai. This is the second known case of white body coloration in this genus. This coloration is related to nycthemeral cycle, the same specimen being whitish at day, and pale green or brown at night.
