The new genus Neoholothele
is herein described based on the results of a recent phylogenetic analysis. This phylogeny, which included representatives of all Theraphosidae
subfamilies, showed that the genus Holothele
, as hitherto defined, does not comprise a monophyletic group. Neoholothele
gen. nov. is diagnosed by the following features: males and females with dark carapace and golden cephalic region; females with striped color pattern on the abdomen dorsum and long and slender spermathecae receptacula; males with retrolateral branch of male tibial spur with apical end wider than proximal end (synapomorphy), with two apical spines. It comprises two species: N. incei
(F. O. Pickard-Cambridge, 1898) comb. nov. and N. fasciaaurinigra
sp. nov., both from northern South America.
The genus Euthycaelus Simon 1889 is diagnosed based on the examination of type-material and additional material from Venezuela and Colombia. The genus now includes: Euthycaelus colonicus Simon 1889, E. norae sp. nov., E. amandae sp. nov.; Euthycaelus steini Simon 1889 is transferred to Psalistops comb. nov. The genus Schismatothele Karsch 1879 is considered a senior synonym of Hemiercus Simon 1903. Schismatothele includes S. lineata Karsch 1879, S. inflata (Simon 1889) comb. nov., S. modesta (Simon 1889) comb. nov, and S. benedettii Panzera et al. 2011. Hemiercus proximus Mello-Leitão 1923, from Cubatão, São Paulo, Brazil, is transferred to Acanthoscurria proxima (Mello-Leitão 1923) comb. nov. Hemiercus kastoni Caporiacco 1955 is considered a species inquirenda pending the examination of the type material.
