Stethorrhagus roraimae Gertsch 1942

Stethorrhagus roraimae Gertsch, 1942 Figs 7A–C, 49 Stethorrhagus roraimae Gertsch, 1942: 13, fig. 36, ♀. Stethorrhagus roraimae – 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, 23C–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. 7C; 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, 45C–F; 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, 45C–F). Type material Holotype BRAZIL • ♀; Roraima, Ireng River; [3°45′31.45″ N, 59°40′47.02″ W]; 15 Aug. 1911; AMNH (re-examined from photos). Description Female, see Bonaldo & Brescovit (1994: 61); male unknown. Additional documentation of the female holotype in Fig. 7A–C. Distribution Known only from the type locality (Fig. 49).

Abstract

Stethorrhagus roraimae Gertsch, 1942 Figs 7A–C, 49 Stethorrhagus roraimae Gertsch, 1942: 13, fig. 36, ♀. Stethorrhagus roraimae – 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, 23C–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. 7C; 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, 45C–F; 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, 45C–F). Type material Holotype BRAZIL • ♀; Roraima, Ireng River; [3°45′31.45″ N, 59°40′47.02″ W]; 15 Aug. 1911; AMNH (re-examined from photos).
