The subgenus Tripteroides of the genus Tripteroides Giles is a complex group of about 50 species occurring from India and Ceylon, through Thailand and Viet-Nam, north to China, Taiwan and Japan, and south through the Philippines, Malaysia, Indonesia, New Guinea, the Solomon Islands, and Australia. Pending a revision of the subgenus we are describing three new species from Malaya and Thailand. We feel that these species draw attention to certain diagnostic characters in this subgenus. We are following the classification proposed by Belkin 1962 who recognized three subgenera as follows Tripteroides for the ornamented species, Rachisoura for nonornamented species with predaceous larvae with incomplete, widely separated maxillary sutures, and Rachionotomyia for all the other nonornamented species. The larval and pupal chaetotaxy and terminology used is also that of Belkin 1962 for the most part. Following Knight 1968, we are labeling the larval basal maxillary hair bmh, having found it to be of some taxonomic value.
