Stethorrhagus nigrinus View in CoL – Bonaldo & Brescovit 1994: 59, fig. 21b–c (transferred from Corinna View in CoL ).

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 View Fig , 23B–D View Fig , 44C–D View Fig , 45C–F View Fig ; 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 View Fig ; 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 View Fig ) (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 View Fig ; Bonaldo & Brescovit 1994: fig. 21b) (posterior border of CO straight; CD’s dorsal reinforcement rods surpassing CO anteriorly in S. papillio – Fig. 45C–F View Fig ).
