Abstract

The 'Cephennomicrus group' of Cephenniini includes nine genera distributed mostly in SE Asia (but with some species known also from other continents, except for the Americas). Four new Oriental species are described: Cephennococcus penangensis sp. n. (W Malaysia), Cephennomicrus matangensis sp. n. (E Malaysia), Cephennomicrus selangorensis sp. n. (E Malaysia), and Trurlia nova sp. n. (E Malaysia). Cephennomicrus selangorensis is unique in having the pronotum in both sexes with broad lateral impressions demarcated from the disc by a sharp ridge, a modification slightly similar to that of only one (Australian) congener.
