Stethorrhagus roraimae View in CoL – Bonaldo & Brescovit 1994: 61, fig. 23a–b, ♀.

Diagnosis

Females are similar to those of S. hyula , S. nigrinus and S. papilio sp. nov. by the epigynal plate without VEP and with the CO disposed anteriorly in relation to SI ( Figs 7B–C View Fig , 23C–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. 7C View Fig ; Bonaldo & Brescovit 1994: fig. 23a) (present in S. hyula – Bonaldo & Brescovit 1994: fig. 19c); from those of S. nigrinus and S. papillio by the small CO, with its width nearly 12 times smaller than the distance between the CO and the posterior margin of the epigynal plate ( Figs 44C–D View Fig , 45C–F View Fig ; Bonaldo & Brescovit 1994: fig. 23a) (relatively large CO, with width four times smaller than the distance between the CO and the posterior margin of epigynal plate in S. nigrinus and S. papillio – Figs 44C–D View Fig , 45C–F View Fig ).
