Purpose To describe a new genus and two new species of chewing lice from Southeast Asian trogons (Trogoniformes). These lice belong in the Philopterus-complex.
Methods Slide-mounted lice were examined in a light microscope, illustrated by means of a drawing tube, and described using standard procedures.
Results The new genus and species were successfully described.
Conclusions The genus Vinceopterus n. gen. is described from two species of Southeast Asian trogons (Trogoniformes: Harpactes). It presently comprises two species: Vinceopterus erythrocephali n. sp. from three subspecies of the Red-headed Trogon Harpactes erythrocephalus (Gould, 1834), and Vinceopterus mindanensis n. sp. from two subspecies of the Philippine Trogon Harpactes ardens (Temminck, 1826). Vinceopterus belongs to the Philopterus-complex, and thus likely constitutes a genus of head lice. Vinceopterus is the second new genus of chewing lice discovered on Southeast Asian trogons in recent years, the first genus of presumed head lice on trogons worldwide, and the fifth genus of chewing lice known from trogons globally. A translated and revised key to the Philopterus-complex is provided, as well as notes on the various chewing lice genera known from trogons.
