José P.L. Guadanucci, Sylvia M. Lucas, Rafael P. Indicatti & Flávio U. Yamamoto (2007) Description of Guyruita gen. nov nov. and two new species (Ischnocolinae, Theraphosidae). Revista Brasileira de Zoologia 24 (4): 991–996.
The genus Guyruita gen. nov nov. and two new species from Brazil are described. Holothele waikoshiemi (Bertani & Araújo, 2005) from Venezuela is transferred here to the new genus. Guyruita gen. nov. differs from the remaining Ischnocolinae by the following features: labium densely occupied by a lot of cuspules (more than 100), intercheliceral intumescence absent, posterior sternal sigilla remote from margin, tarsal claws without teeth, tarsal scopula I-II undivided (tarsus II with a line of sparse setae, which does not divide the scopula), III-IV divided.
