COMMENTS. Bianor piratus was described from the holotype female and four paratype females collected from Dhupjhora, Gorumara National Park, West Bengal [Sen et al., 2015]. A detailed examination of the female specimen recently collected from West Bengal and its comparison with the images of presumably one of the paratypes provided to JC by Prof. Dinendra Raychaudhuri has revealed that B. piratus actually belongs to the genus Carrhotus . The epigyne with longitudinal depressions separated by a septum and the internal structures with long insemination ducts rising anteriorly and looping before entering the anterior region of the elongated spermathecae are identical to those of C. sannio (cf. Figs 28–30 with Figs 25, 26, 27 and figs 67–70 in Żabka [1985]). Thus it is safe to conclude that this species is to be a member of Carrhotus and be considered a junior synonym of C. sannio .
