description: <i>Sisyphus auricomus</i> Daniel &amp; Davis sp. n. (Figs. 14D, F; 15C) ZooBank: http://zoobank.org/ B1E48C14-84C3-487F-AC44-E1728AAA1C7D <b>Diagnosis</b>: <i>Sisyphus auricomus</i> <b>sp. n.</b> is close in appearance to <i>S. oralensis</i>. However, the new species differs by bearing thick and short golden setae on the pronotum. The directional projection of setae is well-defined (Fig. 14F). Furthemore, the genitalia differ from those of <i>S. oralensis</i> by lacking a dorso-tranverse notch on the apex of the parameres (Fig. 15C). <b>Description</b>: Male holotype: <b>Size</b>. Length: 4.2 mm; width: 2.2 mm. <b>Colour</b>. Body brown with golden setae; antennal club and setae brown. <b>Head</b>. Long setae on dorsal surface; anterior edge of clypeus cleft between medial teeth, convex lateral sinuosity extending to clypeo-genal suture; no indentation at the clypeo-genal suture; rounded protrusion antero-laterally on genae. Surface of frons and vertex setose with ocellate punctation. <b>Pronotum</b>. Maximum width as long as maximum length; golden setae arranged evenly between punctation, setae absent from the distinct rounded bald spots on central disc (Fig. 14F); coarse ocellate punctation. Complete lateral prothoracic ridge separating pronotal disc and prothoracic episternum. <b>Elytra</b>. Ovoid, interstriae with evenly distributed setae; striae with distinct crenulate double line, which is interrupted by fine, minute and ocellate punctures; granulation and depressions basally on elytral striae 1–4. Hind wing and venation fully developed. <b>Pygidium</b>. Narrow basally; densely setose with ocellate punctation. <b>Sternites</b>. Edges between abdominal sternites finely crenulate with setigerous punctures; setae arranged in rows laterally; meso-metasternal suture visible; meso- and metasternum densely punctate and setose. Mesepimerum and metepisternum finely punctate and setose. <b>Legs</b>. In ventral view, profemur carinate antero-laterally, punctate and internally pubescent with a lateral row of fine and well-developed setae; meso- and metafemur densely punctate and setose; meso- and metatrochanter contiguous with femur, metatrochanter projected slightly backwards; metacoxa punctate and shagreened ventro-anteriorly; 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 metatarsus five-segmented, with two claws, setose laterally; first tarsal segment of meso- and metathoracic legs with a row of strong setae on the external edge. <b>Aedeagus</b>. Phallobase weakly sclerotized; parameres simple, lacking dorso-transversal excavation; apex relatively truncated (Fig. 15C). <b>Morphological variation</b> <b>Size:</b> Male: Length: 3.9–5.0 mm; width: 2.0– 2.5 mm; Female: Length: 3.7–5.0 mm; width: − 1.9–2.6 mm <b>Male</b>. Meta- and mesotibia curved; last abdominal sternite narrowed medially (Fig. 1A). <b>Female</b>. Meta- and mesotibia almost straight; last visible abdominal sternite not constricted medially (Fig. 1B). <b>Examined type material</b> Holotype: (&amp;male; TMSA) MOZAMBIQUE, Sofala, Gorongosa National Park (near Chitengo) Sandforest 18°57’24”S 34°20’24”E, 26 m, 14.vi.2014, pitfall, h. dung, leg: GM Daniel Paratypes: (23&amp;male;, 20&amp;female; TMSA; 25&amp;male;, 18&amp;female; SANC; 18&amp;male;, 25&amp;female; UPSA) with the same data as the holotype.

(1&amp;male;, 1&amp;female; HNHM) <b>TANZANIA</b>: Usambaras Mts, Mafi Hills Plateau, 1200 m, 26.xii.1985, Usambara rain Forest Project. Peregovits <b>Distribution</b>: <i>S. auricomus</i> <b>sp. n.</b> may be restricted to Central Mozambique (Beira, Cheringoma, Dondo and Gorongosa) where it is associated with shaded vegetation between the Zambeze and Púnguè rivers (Fig. 16). It was recorded from sandforest and dense woodland in Gorongosa National Park (10 km from northern Chitengo), but was completely absent from surrounding grassland of the same area (Daniel, 2014, unpublished data). In Cheringoma, it has been collected in dense riverine forest (de Medeiros, <i>pers. communication</i>). <b>Etymology</b>: The species name refers to the setae, which are distinctly golden-coloured. <b>Remarks</b>: It should be noted that <i>S. auricomus</i> <b>sp. n.</b> is similar to the eastern African species <i>Sisyphus werneri</i> Montreuil, 2017. However, they can be easily separated by the presence of yellow setae and strong serration on the mid-internal margin of the metatibia in <i>S. werneri</i> whereas, in <i>S. auricomus</i> <b>sp. n.</b>, the internal margins of the metatibiae are weakly dentate with golden setae. Furthermore, <i>S. werneri</i> differs by the two distinct patterns of punctation on the pronotum, smaller medially and larger laterally, unlike in <i>S. auricomus</i> <b>sp. n.</b> where punctures are roughly of the same size. In addition, the genitalia in <i>S. werneri</i> are markedly different compared to <i>S. auricomus</i> <b>sp. n</b>.
