Description of <i>Cypturus zappii</i> n. sp. from Sri Lanka (Coleoptera: Histeridae)

Abstract

A new species of the Indo-Malayan genus Cypturus Erichson 1834 is described and compared with the other five congeneric species currently known. Male genitalia and a peculiar sexual dimorphism of female pygidium are illustrated in detail. Holotype ♂ and allotype ♀ are housed in the collection of the Civic Museum of Natural History of Milan (Italy). It is the third species reported for Sri Lanka after Cypturus aenescens Erichson 1834 and Cypturus thugi Lewis 1894.
