Resumen

ABSTRACT – We propose establishing a new genus of mygalomorph spiders in the family Theraphosidae Thorell, 1869, from the Province Calca, Department of Cusco, Peru. The monotypic genus Allpamayu n. gen. with its type species Allpamayu suyuwixsa n. gen, n. sp. is described. Allpamayu n. gen. differs from the known Ischnocolinae Simon, 1892 by the following unique combination of characters: abdomen with stripes, labium with a low number of cuspules, and clavate trichobothria on tarsi forming two parallel rows along half of tarsus length. Additional characters are palpal bulb of males with two keels, metatarsal ventral tumescence on the first pair of legs, cymbium with long erected setae, spermathecae of females with large subquadrate receptacles and a short wide duct oriented laterally and pointing upwards carrying two to three rounded lobes. © BioOne
