Diagnosis.

Large (4.5-5.3 mm). Fore wing with Cu1a and 2 m-cu complete and as thick as other veins. Tegula with posterior inner corner inwardly produced. Both sexes black marked with various shades of ferruginous. Male with sternum VII raised postero-medially to form a postero-ventrally directed tubercle.

Description.

Female ( Figs 11, 13, 15 ): Black. The following are yellowish ferruginous: underside of pedicel and flagellomeres (most noticeably underside of antennal club); tegula anteriorly and posteriorly; scutellar lamella laterally; apex of all femora; dorsal and anterior aspects of fore tibia; anterior aspect of middle and hind tibiae; proximal four tarsomeres of fore leg. Ferruginous are: mandible (except base); labrum; upperside of antenna; narrow and short band medially on pronotal dorsum; tegula medially; posterior bands (reaching sides and progressively narrower) on terga I - V; narrow posterior bands on sterna II - V (in some specimens); tibia and tarsomeres (other than for parts listed above) of all legs. Wings lightly browned; veins brown.

Length: 5.0-5.3 mm (average of 3: 5.1 mm); length of fore wing 3.0-3.2 mm (average of 3: 3.1 mm); hamuli 5.

Head in front view 1.3 × as wide as long; finely microreticulate (shagreened), moderately shiny, with shallow, indistinct punctures (more discernable on frons and vertex than on clypeus); POL: OOL = 1: 0.82. Clypeus 1.5 × as wide as long; anterior margin evenly emarginate; antero-lateral angles rounded.

Mesosoma microreticulate (shagreened), moderately shiny, with close punctures much larger than those on head.

Gaster very finely microreticulate, moderately shiny, with a few punctures (smaller than those on mesosoma) postero-medially on terga I and II.

Setae short and fine throughout.

Male ( Figs 12, 14, 16-18 ): Black. Nature and distribution of markings very similar to those of female. Labrum of some specimens (including holotype) yellowish-ferruginous rather than ferruginous and therefore contrasting markedly with black clypeus. Tergum VI with a narrow ferruginous posterior band. Surface sculpture and setation as in female.

Length: 4.5-4.8 mm (average of 3: 4.6 mm); length of fore wing 2.8-3.1 mm (average of 3: 2.95 mm); hamuli 5-6.

Head in front view 1.3 × as wide as long; POL: OOL = 1: 0.82. Clypeus 1.5 × as wide as long.

Tergum VII with disc in proximal third slightly depressed, apico-medially with a narrow, subparallel-sided slit, and with lobes flanking slit rounded. Sternum VII raised postero-medially to form a postero-ventrally directed tubercle.

Etymology.

Named for Caroline Mayer of BIOTA-Southern Africa, Hamburg University, who collected the material during her studies in Namaqualand.

Geographic distribution.

Known only from two contiguous localities situated in the Macchia (Fynbos) of the Kamiesberg.
