Abstract	A new species, Homalomena giamensis L.S.Tung, S.Y.Wong & P.C.Boyce, is de scribed and illustrated from karst limestone formations at Kampung Giam, Kuching Division, SW Sarawak, to where it is locally endemic. As part of an ongoing project to investigate triggers and barriers in specia tion processes in Homalomena, observa tions of the pollination of Homalomena giamensis were undertaken to record inflorescence mechanics, interactions with insect visitors, and determine the pollina tor. Five insect genera visited during anthesis-Diptera: Drosophilidae (Coloca siomyia); Coeleoptera: Chrysomelidae: (Chaloenus & Dercetina sp.); Nitidulidae (genus undetermined), and Scarabaeidae: Rutelinae (Par astasia bimaculata Guerin). The pollinator was determined to be the ruteline scarab. Parastasia bimaculata is a rather widespread species in tropical Asia, and has previously recorded as a pollinat ing agent for one Bornean Homalomena. A review of pollination studies of tropical Asian aroids to date is given.
