Griphomyia (Diptera, Dolichopodidae, Peloropeodinae) a new genus from southern Thailand

Griphomyia gen. nov. with G, gravicaudata sp. nov. as type species, is described from rainforest in southern Thailand. Although it possesses a stalked hypopygium which is considered as an ancestral feature, the presence of symmetrically sclerotized pseudotracheae, denticulate epipharyngeal prongs, and a wing boss, all indicate that the new genus is quite derived. The morphology of the male genitalia places it rather in the Peloropeodinae with encapsulated hypopygium than in the Sympycninae with an apical, sessile hypopygium.
