description: <i>Sisyphus bicuariensis</i> Daniel &amp; Davis sp. n. (Fig. 3A). ZooBank: http://zoobank.org/ E02CDE50-8BB1-45D9-87A9-610A7C3713A0 <b>Diagnosis</b>: <i>S. bicuariensis</i> <b>sp. n</b>. resembles <i>S. trichodichromicus</i> Montreuil, 2015. Both bear bicoloured setae. However, <i>S. trichodichromicus</i> bears a shallow notch separating the medial teeth from the blunt lateral teeth; the clypeo-genal suture shows an obtusely angled cleft; and the genae are simple and arcuate. This differs to <i>S. bicuariensis</i> <b>sp. n.</b>, where a markedly deep notch separates the medial teeth from the sharp lateral teeth; the clypeo-genal suture shows a rectangular cleft; and the genae are long and virtually parallel. Additionally, the shapes of the parameres are different in both species. <b>Description</b>: Male holotype: <b>Size</b>. Length: 4.2 mm; width: 2.2 mm. <b>Colour</b>. Black body with grey and black setae (Fig. 5G); clypeus shiny brown antero-laterally; meso- and metasternum black with brown and white setae; antennal club brown. <b>Head</b>. Clypeus upcurved antero-laterally; margin between medial teeth straight; a deep notch between medial and lateral teeth. Clypeo-genal suture with a rectangular cleft; genae long and virtually straight. Frons and vertex with dorsal ocellate punctation and setation. Frons declivous dorso-medially; epicranial suture visible; vertex with a few granules antero-medially. <b>Pronotum</b>. Convex with maximum width longer than maximum length; disc bearing three depressions and ocellate punctation; setae black and grey medially on the central disc, grey laterally; setae on pro-episternum grey, well-developed antero-laterally. A complete lateral prothoracic ridge between the pronotal disc and pro-episternum. <b>Elytra</b>. Narrow posteriorly bearing thicker black setae alternating with thin and thick grey setae either in equal proportion (1:1) or with less grey setae; weakly developed tufts of setae protrude from the epipleurae below the edge of the elytra (&lt;5) (Fig. 5H); elytral surface crenulate with distinct double crenulate line, which is interrupted by fine, ocellate strial punctures; elytral striae with minute punctation; granulation and depressions basally on elytral striae 1–4. <b>Hind wing</b>. Wing and venation fully developed. <b>Pygidium</b>. Bearing scattered setae and ocellate punctation; narrow basally. <b>Sternites</b>. Margin between abdominal sternites finely crenulate; setation well-developed laterally, less so medially; punctation dense laterally and sparse medially; meso-metasternal suture visible; meso- and metasternum densely punctate with matted setae antero-laterally; metasternum with a punctate depression postero-medially. Mesepimerum and metepisternum finely punctate and setose. <b>Legs</b>. In ventral view, profemur punctate and pubescent, carinate antero-laterally with a lateral row of fine and well-developed setae; in lateral view, meso- and metafemur with granulation, also densely punctate and setose; meso- and metatrochanter contiguous with femur, metatrochanter larger and slightly projected backwards; metacoxa punctate and shagreened ventro-anteriorly; protibia with three teeth and a single terminal spine; mesotibia punctate and setose with two terminal spines; metatibia densely setose, serrated laterally with two spurs; pro-, meso- and metatarsus five-segmented, with two claws, setose laterally; first tarsal segment of meso- and metathoracic legs with a row of dense setae on the external margin. <b>Aedeagus</b>. Phallobase slightly curved. Median lobe clearly visible. Parameres (Fig. 6A). <b>Morphological variation</b> <b>Size</b>: Male: length: 5.0–4.0 mm; width: 2.6–2.0 mm; Female: length: 4.9– 4.1 mm, width 2.7–2.0 mm. <b>Male</b>. Meta- and mesotibia curved; with a carina on the dorso-posterior edge of the meta- and mesofemur; last abdominal sternite narrowed medially (Fig. 1A). <b>Female</b>. Meta- and mesotibia almost straight; lacking a carina on the dorso-posterior margin of the meta- and mesofemur; last visible abdominal sternite two times wider than in males (Fig. 1B). <b>Examined type material</b> Holotype: (&amp;male; SANC) ANGOLA, Bicuari NP (15.375173°S 14.752320°E) (2 km N Camp); 18.xii.1974; leg: Davis &amp; Temby /1671/, / Ex coll.

(1&amp;male;, 1&amp;female; SANC) ANGOLA, Huila; 22.xii.1974, leg: Davis &amp; Temby /1683/, / Ex coll. CSIRO, Div. Entomology, South Africa Station /. <b>Additional examined type and</b> <b>non-type material</b>: <i>S. trichodichromicus</i> (Holotype: MHNH, through photograph without locality data); (3&amp;male;, 4&amp;female; TMSA) ZAMBIA, Liuwa Plains; 14.643259°S 22.626423°E, 29–30.xi.2003, 1050 m, leg: Deschodt &amp; Groenewald. (2&amp;male;, 4&amp;female; SANC) ZAMBIA, idem; (2&amp;male;, 2&amp;female; UPSA) ZAMBIA, with the same data. <b>Etymology</b>: Patronym is a noun in apposition, which reflects the name of the area in which the majority of type specimens were collected: Bicuari National Park, South Angola. <b>Distribution</b>: The new species may be associated with unshaded vegetation and open woodland in southern Angola (Fig. 7).
