Sisyphus confrater Kolbe, 1914  

Kolbe 1914: 317; Haaf 1955: 376;

Type local: Bukoba ( Tanzania)

Size: Male: length: 9.0–5.0 mm; width: 4.8–3.0 mm. Female: length: 9.2–5.0 mm; width: 4.5–3.0 mm

Diagnosis: N. setiger   is distinguished from other members of the barbarossa   speciesgroup, by a combination of the following features: a triangular protrusion on the midposterior edge of the metafemur in males. Additionally, the projected metatrochanter is relatively short, comprising ¼ of the total length of the metafemur in males.

Examined non-type material: See Supplementary information.

Distribution: As defined by Montreuil (2015b), N. setiger   is distributed in moist lowland and upland vegetation from northeast to southern Africa ( Fig. 19 View Fig ).

Remarks: We have compared Kenyan specimens identified as N. setiger   with southeast African specimens identified as N. confrater   by Paschalidis (1974). Females of N. confrater   and N. setiger   are close morphologically making it difficult to separate them into species. However, we have observed that males of southern Africa “ N. confrater   ” bear a short blunt triangular projection on the mid-posterior edge of the metafemur and a short projecting metatrochanter. By contrast, males of east African “ N. setiger   ” have a sharp projecting spine on the mid-posterior edge of the metafemur and a metatrochanter as large as in Neosisyphus jossoi Montreuil, 2015   .

Montreuil (2015b) synonymized N. confrater   with Neosisyphus setiger (Roth 1851)   . The synonymy seems to be based on the holotype female of N. setiger   from Ethiopia and a lectotype male of N. confrater   from Tanzania. This is questionable as females are often difficult to separate into species as stated above. Furthermore, although the photograph of a major male of N. setiger ( Montreuil 2015b)   closely resembles “ N. confrater   ”, there is no indication of where the individual was collected. Nevertheless, we have retained the name N. setiger   for southern African material as we have not been able to compare it with the type and non-type material used in Montreuil’s study (2015b).
