Sisyphus fortuitus Péringuey, 1901

Péringuey 1901: 103; Arrow 1927: 464; Gillet 1911: 23; Haaf 1955: 371; Ferreira 1972: 819; Montreuil 2015b: 9.

Type locality: Durban, Natal (South Africa)

Size: Male: length: 11.1–9.0 mm; width: 5.7–5.0 mm. Female: length: 11.5–9.0 mm; width: 6.0– 4.4 mm.

Diagnosis: Neosisyphus fortuitus is distinguished from other members of the spinipes species group in southern Africa by lacking a spine or projection on the mid-posterior edge of the metafemur. In addition, the projecting metatrochanter is almost ½ of the length of the metafemur in major males. The parameres are distinctly different to those of the other two species within the group (Fig. 21A).
