Males are narrower and more cylindrical than Psilonychus deridens and Psilonychus eckloni and clothed like P. eckloni with whitish or slightly flavescent scales which form on each elytron four uninterrupted bands separated by three narrow denuded lines. The hairs along the margins of the pronotum, the base especially, are plainly flavous. The clypeus is more sharply emarginate in the centre and narrower than in P. eckloni.
