Abstract

A total of 233 voucher specimens of weevils (subfamily Rhynchophorinae) at the Sarawak Museum and the Unimas Museum were evaluated in this study. These specimens were collected over a period of 113 years from 1891 to 2004. Results from this study reveals that the rhynchophorine weevils of Sarawak are represented by three tribes, 11 genera and 27 species. The tribe Rhynchophorini consists of four genera (36.4%) and eight species (29.6%), Ommatolampini, represented by a single genus (9.1 %) with two species (7.4%) and Sphenophorini, with six genera (54.5%) and 17 species (63%). Rhynchophorus schach seems to be the most abundant species representing 12.4% of the total individuals in voucher collections. Cyrtotrachelus bipartilus, Rhynchophorus ferrugineus, Cosmopolites sordidus and Poteriophorus bouringi are among the less abundant, represented by 0.4 %. Distribution mapping of these weevils shows that the rhynchophorine weevils were distributed throughout Sarawak. Cyrtotrachelus bipartilus is considered rare and also confined to montane areas ofMt. Murud and Mt. Kinabalu.
