GORCZYCA Abstract: The genus Peritropis UHLER from the Oriental Region is revised. Six new species of the genus are described from Brunei, Indonesia, India, Malaysia, Thailand and Vietnam. All type material, except P. lugubris POPPIUS, has been examined. All known species from the Oriental Region are redescribed. Photos of the dorsal habitus of all species are presented and keys to the Oriental species are provided. Key words: Cylapinae, Heteroptera, new species, Oriental Region, Peritropis, taxonomy. Introduction I do not include the illustrations of male genitalia because several species are known The genus Peritropis UHLER is one of the only from females and some only as holo- most numerous genera within the subfamily types; most species can be distinguished on Cylapinae.
