Etymology

The species is named after Gerhard Prinsloo, a famous expert on South African Chalcidoidea, who collected part of the type series and also first noticed and sorted out the SANC specimens as unusual tetracampids.

Description

Female

LENGTH. 1.4–1.6 mm.

COLOUR. Body with yellow and blue-green markings: head mostly yellow apart from black scrobal depression and green metallic occiput and vertex; meso- and metasoma mostly metallic green, except for yellow pronotum, prepectus, acropleuron, tegulae and shoulders of mesoscutum; legs and antennae yellow-brown, except for green metallic anterior parts of hind coxae and black pretarsi ( Figs 2, 3A–C, 4A–B). Wings transparent, veins pale brown, dorsal bristles pale ( Fig. 4C).

HEAD. In dorsal view about 2.0 × as long as broad, vertex smoothly transits to occiput, so occipital margin not traceable ( Fig. 2D). POL about 2.0× OOL, OOL about 2.3× MDO. Head in frontal view 1.2× as wide as high; eye approximately 2.3× as high as broad; ventral margin of torulus situated slightly above virtual line connecting lower margins of eye orbits ( Fig. 2B). Minimum distance between inner orbits about 0.6× width of head. Face smooth, width of scrobal depression about 0.3× that of face ( Fig. 2B). Mouth opening about 1.3 × as wide as malar space (malar space about 0.7–0.8 × as long as mouth opening, Fig. 3F). Inner margins of eyes slightly diverging. Genae nearly straight. Mandibles oriented downwards, bidentate ( Fig. 3F). Malar suture sulcate, complete. Antenna ( Fig. 3E) with scape about 4.8 × as long as wide, pedicel 1.7 × as long as broad. F1 1.5–1.6 × as long as broad, F2 1.2× as long as broad, F3 1.3× as long as broad, F4 and F5 slightly longer than wide, club slightly more than 2.0 × as long as broad, club 3.0 × as long as F5, its segments separated by sutures, terminal spine very short.

MESOSOMA. About 1.5 × as long as broad, weakly alutaceous ( Fig. 2D–F). Pronotum short, conical, about 0.2× as long as mesoscutum. Mesoscutum about 1.8 × as broad as long; mesoscutellum slightly wider than long and slightly longer than mesoscutum, with 2 pairs of strong bristles, its surface alutaceous, posterior ¼ smoother ( Fig. 2D–F). Axilla with two strong bristles. Mesopleuron smooth and flat, mesopleural suture present as a very shallow groove ( Fig. 3A, D). Propodeum as narrow stripe, smooth, without sculpture ( Fig. 3C), its callus with 10 setae.

METANOTUM. With relatively wide, smooth dorsellum, about 0.15 × as long as mesoscutellum ( Fig. 3C). Metapleuron subrectangular, with alutaceous sculpture, nearly flat ( Fig. 3A, D).

FORE WING. Approximately 2.4–2.5× as long as broad ( Fig. 4C), slightly longer than body ( Figs 2A, C, E, 4A). Subcosta of SMV tapering, but not broken when transiting to parastigma, with 5 dorsal bristles ( Fig. 4C), MV slightly longer (about 1.1×) than costal cell, about 0.6× wing width, STV with short petiole, nearly perpendicular to MV, with subtriangular or spherical stigma and short, relatively wide uncus, PMV about 3.4–3.8 × as long as STV ( Fig. 4C). Marginal fringe long, as long as STV, about 2.0–2.5 × as long as width of MV at its broadest part ( Fig. 4C).

LEG. Front leg with a short calcar, about as long as width of its tibia, evenly acute and nearly straight; midtibial spur about 2.0× as long as width of its tibia; hindtibial spur 1.2× as long as width of its tibia.

METASOMA. 1.1–1.2 × as long as mesosoma ( Figs 2A, E, 4A); petiole rather transverse, lightly sculptured ( Figs 2A, C, E, 4A). Gaster about 1.5 × as long as wide in dorsal view ( Fig. 3B–C). Gt2–5 with posterior margins straight ( Fig. 3C); Gt6 nearly straight posteriorly, bearing gastral spiracles ( Figs 3C, 4B); syntergum with a pair of short cerci (each with three long, straight setae) and with a membranous lobe at its posterior end ( Figs 3C, 4B).

Male

Length about 0.9 mm. Very similar to female ( Fig. 4D), but with somewhat longer flagellar segments ( Fig. 4E), 4-segmented tarsi and shorter gaster.

Biology

Unknown.

Distribution

South Africa: Eastern and Western Cape.
