Sisyphus inconspicuus Daniel & Davis  sp. n. ( Figs. 11View Fig, 12DView Fig).

ZooBank: http://zoobank.org/ A8C95127-D39B-4DC7-A564-0F77CCA4AB14

Diagnosis: Sisyphus inconspicuus  sp. n. is similar to S. costatus  ; both bear inconspicuous ocellate punctation on the dorsal surface of the clypeus and frons, however, the vertex bears scattered ocellate punctures in S. costatus  and dense ocellate points in the new species. Sisyphus inconspicuus  sp. n. has a straight margin between the medial clypeal teeth and the anterior margins of the genae are arcuate. In S. costatus  , the dorsal clypeal margin is distinctly concave and curved upwards between medial teeth whereas the genal margin is virtually straight ( Figs. 11G, IView Fig). Additionally, the new species bears setae that are uniformly arranged on the elytra whereas, in S. costatus  , the setae on the elytral interstriae alternate between rows that are dense or less dense.

Description: Male holotype: Size. Length: 7 mm; width: 3.9 mm. Colour. Body and setae brown; meso- and metasternum black; antennae brown. Head. Medial teeth on the clypeus separated by a straight margin; shallowly notched edge between medial and lateral teeth; genal margin arcuate anteriorly. Dorsal surface of the clypeus and frons inconspicuously punctate ( Fig. 11IView Fig); epicranial suture clearly visible; vertex setigerous with dense ocellate punctation. Pronotum. Convex; maximum length equal to maximum width; dorsal surface finely setose with ocellate punctation; setae on the antero-lateral projection well-developed. Complete lateral prothoracic ridge between the prothoracic disc and prothoracic episternum. Elytra. Wider and ovoid proximally, narrow posteriorly; elytral striae minutely punctate and crenulate, characterized by a distinct crenulate double line, which is interrupted by fine, ocellate strial puctures. Granulation and notches basally on elytral striae 1–4; setae evenly distributed on the interstriae. Hind wings and venation fully developed. Pygidium. Setigerous with ocellate punctation arranged in a U-shape. Sternites. Abdominal sternites finely crenulate, setigerous with ocellate punctation; setae arranged in rows laterally; meso-metasternal suture visible, acute laterally; meso- and metasternum densely punctate and setose; a punctate depression present on the postero-medial surface of the metasternum. Legs. In ventral view, antero-lateral carina of profemur punctate, internally pubescent with a lateral row of fine and well developed setae; meso- and metafemur with granulation, densely punctate and setose; meso- and metatrochanter contiguous with femur, metatrochanter slightly projected backwards; metacoxa punctate and shagreened ventroanteriorly; protibia with three teeth and single terminal spine; mesotibia punctate and setose with two terminal spines; metatibia densely setose, serrated laterally with two spurs; pro- meso- and metatarsi five segmented with two claws, setose laterally; first tarsal segment of the meso- and meta-thoracic legs with a row of strong setae on the external edge. Aedeagus. Paremeres simple, symmetric; truncated basally ( Fig. 12DView Fig).

Morphological variation

Size: Male: length: 8.2–6.0 mm; width: 3.8–4.1 mm; Female: 8.0–6.0 mm; width: 3.0– 3.6 mm. Head: In some populations, mainly from the Eastern Cape (The Haven): lateral side of the clypeus is completely smooth as far as the clypeo-genal suture in some specimens; the lateral margin of the genae tends to be less convex; the surface of the clypeus is less setigerous. Colour: Inland populations are black and brown whilst the majority of the coastal population is black although two specimens from Pomene ( Mozambique) are brown. Male: Meta- and mesotibia curved ( Fig. 1HView Fig); last abdominal sternite narrowed medially ( Fig. 1AView Fig). Female: Meta- and mesotibia almost straight ( Fig. 1GView Fig); last visible abdominal sternite not constricted medially ( Fig. 1BView Fig).

Etymology: The species name reflects the inconspicuous punctures on the frons.

Distribution: Sisyphus inconspicuus  sp. n. occurs in South Africa and Mozambique. It has been recorded from moist savanna or dense woodland and riverine vegetation. It has also been collected in dry shaded vegetation along the coastline, in sand forest, and

in dry, dense savanna from KwaZulu Natal ( South Africa) to Sofala Bay ( Mozambique) ( Fig. 13View Fig).
