Remarks. The lectotype of Sciaphilus dividuus is 3.25 mm long. The lectotype of Sciaphilus pruinosus is 3.38 mm long. Both lectotypes are conspecific with the type of Sciaphilus pennatus, thus Sciaphilus dividuus is a subjective junior synonym. We also confirm synonymy of Sciaphilus pruinosus . Chiloneus pennatus is easy to distinguish from all other Chiloneus species by appressed scales on elytra trifid, deeply divided into three piliform lobes apically.
