Diagnosis The female of S. fuscipennis can be separated from that of all other species of this group by the following character combination: T3 anterior of premarginal line impunctate ( Fig. 24F ); propodeum with coarse carinae, not smooth ( Fig. 24E ); anterior margin of apical depression straight ( Fig. 24F ); punctation on discs of T1–T4 fine and shallow ( Fig. 24F ). The male is unknown. Additional material examined No additional material examined. Description Female BODY LENGTH . 5.5 mm . HEAD . Wider than long. Integument black, mandibles dark brownish. Face irregularly and sparsely covered with greyish hair, more densely around basis of antennae and laterally. Clypeus medially with shallow longitudinal depression; coarse punctation, apically sparse (i = 2–4 d), laterally dense (i = 1–2 d). Surface between punctures smooth and shiny ( Fig. 24C ). Malar area medially narrow, slightly curved. Antennal flagella ventrally yellow, dorsally black. Supraclypeal area at upper margin distinctly emarginated and edges slightly extended. Fig. 24. Scrapter fuscipennis ( Friese, 1912 ) , ♀. A . Lateral view. B . Head (dorsal view). C . Scutum and scutellum (dorsal view). D . Metanotum and propodeum (dorsal view). E . Metasoma (dorsal view). F . Terga 1–2 (dorsal view). MESOSOMA . Integument black, pronotal lobe dark brownish to black. Scutum coarsely and irregularly punctate (i = 1–2 d) ( Fig. 24D ). Metanotum about half as long as scutellum. Propodeum anterior wide and coarse longitudinal carinae and posterior finer transverse carinae ( Fig. 24E ). Scutum, scutellum, metanotum, mesepisternum and propodeum sparsely covered with short, brownish to greyish, erect hair. WINGS . Yellowish-brown, stigma and wing venation dark brownish ( Fig. 24A–B ). LEGS . Integument black, fore tibia with yellow spot. Vestiture brown, scopa brownish, partly black ( Fig. 24A–B ). METASOMA . Integument black, marginal zone brownish, generally darkening apically. No basal hair bands on T2–T4, laterally small patches of white, short, erect hair. Prepygidial and pygidial fimbriae dark brownish to black ( Fig. 24F ). Disc of T1 sparsely, shallowly, and finely punctate; punctation on discs of T2–T4 shallower and finer than on T1. Surface between punctures matt. T3–T4 anterior of premarginal line with row of hairs; no row of points anterior of premarginal line ( Fig. 24F ). Male Unknown. Distribution Only known from the type that was collected at an unspecified place in the Cape Province (“Kapland”). Floral hosts Unknown. Seasonal activity September. Remarks Eardley (1996) synonymised this species with S. nitidus .
