Thrasychiroides brasilicus Soares & Soares, 1947a

( Figs 5 A–C; 6A–B)

Diagnosis. Ocularium with 20 small setae, with white patch between eyes (according to Soares & Soares 1947a). Chelicera massive, second segment inflated and covered with setae except in lateral surface, movable finger with median large tooth followed by 13 small teeth, fixed finger with 12 small teeth on distal half. Pedipalpal claws with 14 teeth. Penis with posterior portion of glans two times larger than the anterior part, base concave, shoulders slightly narrower than the arms area, with angular laterals not bearing spines ( Fig. 5 B–C). Inflated glans with a pair of dorso-lateral setae with acuminate tips ( Fig. 5 A). Ventral arms long and slightly S-shaped, with swollen and knob-like tips. Distal end of stylus with hook-like spine, mostly covered by a membranous sac ( Fig. 6 A–B).
