Abstract
A new species of crane fly, Helius (Helius) darlingtonae, is described from Aripo Caves, Trinidad. Both sexes possess a single segmented ant ennal flagellum, a feature unique within the Tipulidae, and of rare oc currence within the Diptera in general. Helius darlingtonae n. sp. is apparently an obligate cave dweller, the first noted in this habitat f or this genus in the New World and the first species in the genus reco rded from Trinidad. Based on characteristics of the male genitalia, H. darlingtonae n. sp. appears most similar to H. distinervis Alexander from Panama.
