Stethorrhagus nigrinus

Stethorrhagus nigrinus (Berland, 1913) Figs 44, 50 Corinna nigrina Berland, 1913: 99, ♀. Stethorrhagus nigrinus – Bonaldo & Brescovit 1994: 59, fig. 21b–c (transferred from Corinna). Diagnosis Females are similar to those of S. hyula, S. roraimae and S. papilio sp. nov. by the epigynal plate without VEP, with CO disposed anteriorly in relation to SI (Figs 7B–C, 23B–D, 44C–D, 45C–F; Bonaldo & Brescovit 1994: figs 19c–d, 21b–c, 23a). They differ from those of S. hyula by the epigynal plate without a posterior median half-moon-shaped sclerotization (Fig. 44C–D; Bonaldo & Brescovit 1994: fig. 21b–c) (present in S. hyula – Bonaldo & Brescovit 1994: fig. 19c); from those of S. roraimae by the relatively large CO, with width four times smaller than the distance between the CO and the posterior margin of epigynal plate (Fig. 44C–D) (small CO, with width nearly 12 times smaller than the distance between the CO and the posterior margin of the epigynal plate in S. roraimae (Bonaldo & Brescovit 1994: fig. 23a); and from those of S. papillio by the posterior border of the CO sinuous; CD’s dorsal reinforcement rods not surpassing CO anteriorly (Fig. 44C–D; Bonaldo & Brescovit 1994: fig. 21b) (posterior border of CO straight; CD’s dorsal reinforcement rods surpassing CO anteriorly in S. papillio – Fig. 45C–F).
