A new subgenus and three new species of parasitic lice (Phthiraptera: Ischnocera) in the Oxylipeurus-complex are described and illustrated. Forcipurellus new subgenus is part of the genus Reticulipeurus Kéler, 1958, and only includes species parasitic on partridges of the genus Arborophila Hodgson, 1837. The new species are: Reticulipeurus (Forcipurellus) diki new species ex Arborophila rubrirostris (Salvadori, 1879); Reticulipeurus (Forcipurellus) bracatus new species ex Arborophila atrogularis (Blyth, 1849); Reticulipeurus (Forcipurellus) longistylus new species ex Arborophila rufogularis guttata Delacour & Jabouille, 1928 and two other host subspecies. In addition, we redescribe the species Reticulipeurus (Forcipurellus) formosanus (Uchida, 1917) ex Arborophila crudigularis (Swinhoe, 1864) and Reticulipeurus (Forcipurellus) nitzschi Kéler, 1958 ex Arborophila torqueola torqueola (Valenciennes, 1825) and Arborophila torqueola millardi (Baker, 1921). Also, we briefly discuss four additional species that could not be described based on the specimens examined. A key to identify all species in the subgenus Forcipurellus is provided, as well as an emendation to include Forcipurellus in a previously published key to the Oxylipeurus-complex.
