Scrapter carysomus Davies View in CoL in Davies et al., 2005: 149 View Cited Treatment (in key), 155–158, figs 9–12, holotype ♂ (type locality: Farm Glen Lyon, Nieuwoudtville, South Africa) (SANC), examined.

Diagnosis

The female of S. carysomus is described here for the first time. It can be separated from that of all other species in this group by the following character combination: propodeum dorsolaterally (lateral to the matt propodeal triangle) very finely shagreened and matt ( Fig. 4D View Fig ), foreleg blackish-brown, sometimes femur apically slightly dark yellowish-brown, disc of T2 finely and sparsely punctate or without punctation, apical tergal depressions broad, yellowish translucent with the adjacent apical area of the disc crescent-shaped dark reddish ( Fig. 4B View Fig ).

The male is characterized by foreleg with medio- and distitarsi completely bright yellow, basitarsus and tibia predominantly yellow ( Figs 3 View Fig , 5A View Fig ), mid and hind leg with tarsi predominantly dark yellowish-brown to blackish ( Fig. 5A View Fig ); hind tibia apically on inner side with hairs relatively short ( Fig. 6A View Fig ), genitalia as in Fig. 6B View Fig . The male was described in detail by Davies et al. (2005), so the description is not repeated here but images ( Figs 3 View Fig , 5–6 View Fig View Fig ) are provided to facilitate its identification.

Mesoscutal disc between punctures strongly reticulate and slightly matt; disc relatively densely (i= 1–2d) and distinctly but relatively shallowly punctate ( Fig. 4C View Fig ). Metanotum slightly shorter than basal area of propodeum, apically with broad and distinct carinate depression ( Fig. 4D View Fig ). Propodeum on basal half relatively indistinctly and finely carinate ( Fig. 4D View Fig ).
