Abstract


Umbyquyra gen. nov., a new Theraphosinae genus with stridulatory bristles on the palpal trocanther of pedipalp trochanter and first leg, is proposed. The genus differs from the other genera with stridulatory bristles on the same segments, Acanthoscurria Ausserer, 1871, Cyrtopholis Simon, 1892, Longilyra Gabriel, 2014 and Nesipelma Schmidt & Kovarik, 1996, by having a palpal bulb with a very short and acuminate embolus and four short keels; separated tibial apophysis; and female spermathecae resembling those of Cyrtopholis, with two seminal receptacles with elongated ducts emerging from a common area. Cyrtopholis palmarum Schiapelli & Gerschman, 1945 and C. schmidti Rudloff, 1996 from Brazil and Acanthoscurria acuminata Schmidt & Tesmoingt in Schmidt, 2005 from Bolivia are transferred to the new genus. The female of Umbyquyra palmarum (Schiapelli & Gerschman, 1945) gen. et comb. nov. and the male of U. schmidti (Rudloff, 1996) gen. et comb. nov. are described for the first time. Cyrtopholis zorodes Mello-Leitão, 1923 is considered a junior synonym of Acanthoscurria gomesiana Mello-Leitão, 1923 and Cyrtopholis meridionalis (Keyserling, 1891) is considered a nomen dubium. Eight new species from Brazil are described: Umbyquyra paranaiba gen. et sp. nov., U. cuiaba gen. et sp. nov., U. araguaia gen. et sp. nov., U. sapezal gen. et sp. nov., U. belterra gen. et sp. nov., U. caxiuana gen. et sp. nov., U. tucurui gen. et sp. nov. and U. tapajos gen. et sp. nov. Data and maps on the geographic distribution are provided.
