Sisyphus gazanus Arrow, 1909 (Figs. 11, 12C).

Arrow 1909: 518; Gillet 1911: 23; Arrow 1927: 461; Haaf 1955: 361; Ferreira 1972: 799; Schäfer & Fischer 1992: 129.

Type locality: Chirinda, Mashonaland (Zimbabwe)

Size: Male: length: 5– 4.5 mm; width: 3.1– 2.5 mm; Female: length: 5– 4.4 mm, width 3.1– 2.4 mm.

Diagnosis: S. gazanus is relatively close in appearance to S. inconspicuus sp. n. However, it is easily distinguished by a combination of features as follows: S. gazanus has a somewhat shallow depression dorsally on the genae; the dorsal surface of the head (vertex and frons) is entirely covered by distinct ocellate punctures (Fig. 11J); the pronotal disc shows a patchwork of bald areas and sparse short setae. In addition, the parameres of both species are distinctly different (Figs. 12 C–D).

Distribution: Sisyphus gazanus is associated with cooler conditions in highland forest in Zimbabwe and Malawi. It was described from Mount Chirinda (Zimbabwe) at the southern end of the Inyanga Highlands and Chimanimani Mountains. This range may have acted as a corridor into Malawi where the species has also been recorded from Mount Mulanje and Mount Gomoloti (Fig. 13). So far, it has not been recorded under cooler, shaded conditions on the intervening Muchinga Mountains (Manica, Mozambique) or Mount Binga (19.78°S 33.30°E).
