Polylopha cassiicola is recorded from Hong Kong. Adults and genitalia are illustrated. Key words: taxonomy, Oriental fauna, Southeast Asia, China, genitalia Introduction The tribe Polyorthini (Tortricidae, Chlidanotinae) is distributed in the Palaearctic, Oriental, and Neotropical regions; 22 genera and 148 species are known (Brown et al., 2005). Adults usually have a dark brown forewing with raised scale tufts (Acleris-like), and the male genitalia have a membranous valva with a longitudinal split containing a hairpencil arising from the eighth segment. Diakonoff (1974) reviewed the tribe in South Asia, treating six genera and 28 species. The fauna of the tribe has received little attention in the area since then. An examination of material from Thailand and Hong Kong revealed a new species of the genus Lopharcha and a new record of Polylopha cassiicola Liu & Kawabe, 1993. I describe the former as new to science and record the latter from Hong Kong, with illustrations of adults and genitalia.
