New species of the harvestmen Hutamaia (Laniatores: Gonyleptidae: Ampycinae) and generic diagnosis

Tourinho, Ana LúciaMendes, Amanda Cruz

We add three new species to the formerly monotypic Amazonian Hutamaia, Hutamaia maceta sp. nov. , Hutamaia plei sp. nov. and Hutamaia trompsonica sp. nov. and compare them with the type species, Hutamaia caramaschii Soares & Soares, 1977. Hutamaia was known only from two localities: Humaitá, Amazonas, Brazil (type locality of the type species), and Madre de Dios, Peru. Herein we record species from the following additional localities, all in Brazil: Coari, Codajás, Juruá, Jutaí, Manacapuru, Tefé (state of Amazonas) and Gurupá (state of Pará), indicating that the genus has a widespread distribution in the Brazilian and Peruvian Amazon. Hutamaia is newly diagnosed by having yellowish granules on dorsal scutum, armature of coxa IV of males, metatarsi with yellow rings, ventral plate of penis trapezoid with V-shaped cleft, bearing two pairs of longitudinal rows of setae, and glans without dorsal or ventral processes. The genus is likely closely related to Licornus Roewer, 1932, from which it differs by the shape of the ventral plate of the penis and lack of dorsal process of glans.(AU)
