Stethorrhagus limbatus Simon, 1896: 421, ♂ ♀.

Stethorrhagus abrahami Mello-Leitão, 1948: 183, fig. 24, ♂ (synonymized with Stethorrhagus limbatus by Bonaldo & Brescovit 1994: 39, figs 8a–b, 9a–e).

Diagnosis

Males of Stethorrhagus limbatus differ from those of all other species with deep sternal excavations by the VL entire and the dVL absent (Fig. 10A–D; Bonaldo & Brescovit 1994: fig. 9a–c) (VL bifid, composed of vVL and dVL in all other species – Figs 3E, 7E–F, 13A–B); they are similar to those of S. penai by the SePP indistinguishable from the embolar base; absence of TP1 and presence of TP2 (Bonaldo & Brescovit 1994: fig. 15a–b) but may be recognized by the absence of the dVL and by the median sector of the spermophore coiling on the prolatero-basal region of the tegulum (Figs 10A–D; Bonaldo & Brescovit 1994: figs 9b–c) (dVL present, median sector of the spermatophore coiling on the ventral region of tegulum in S. penai – Bonaldo & Brescovit 1994: fig. 15b). Females differ from those of other species with the CO disposed anteriorly in relation to the SI and without VEP ( S. nigrinus, S. hyula and S. roraimae) by the CO composed of a large transversal excavation (nearly four times as wide as long) (Fig. 11C–E; Bonaldo & Brescovit 1994: fig. 9v) and by the wide longitudinal rods on the CD wall (Fig. 11D; Bonaldo & Brescovit 1994: fig. 9e) (CO narrower and rods inconspicuous in S. nigrinus and S. hyula; not observed in S. roraimae – Bonaldo & Brescovit 1994: figs 19c–d, 21b–c, 23a–b).
