Description.
Holotype (Female). Head. Head in dorsal view much wider than long (12:7), subequal to width of mesosoma (Fig. 12A, D); POL: 5; LOL: 3; OOL: 5 (Fig. 12A); ocelli large, LOL slightly longer than diameter of lateral ocellus (9:7); vertex behind ocelli nearly flat in lateral view; eye large and without setae; inner orbits, frons and temple with few sparse setae; above antennal sockets, face and cheek with few long setae; antenna slightly shorter than body length (10:13); scape and pedicel with scattered setae; A3-A15 with dense and short setae; antennal segments in following proportions (length:width): 12:3; 6:3; 9:2; 10:2; 6:2; 5:3; 4:3; 4:3; 4:3; 4:3; 4:3; 4:3; 4:3; 4:3; 8:3 (Fig. 12A).
Mesosoma. Pronotum in dorsal view punctate with whitish long setae; pronotal shoulders angled; upper part of lateral pronotum smooth and concave in the middle, lower part of lateral pronotum punctate; mesoscutum smooth and convex with pairs of long setae in front of scutellar pit; notauli present with 6 very small pits on anterior margin (Fig. 12E); humeral sulcus deep and short, as long as length of tegula; scutellum smooth and slightly convex, posterior rim rounded (Fig. 12E); anterior scutellar pit small and deep, much shorter than remaining scutellar disc, distinctly crenulate at bottom, median keel absent (Fig. 12E); mesopleuron smooth with deep crenulate line along posterior margin; metapleuron rugose and covered with dense whitish long setae.
Wings. Radial cell completely closed, 1.6 × as long as wide and 0.6 × as long as marginal vein (Fig. 12A).
Legs. Fore and mid legs slender; hind tibiae incrassate posteriorly, its maximum width slightly wider than hind femora (11:10).
Metasoma. Petiole short and expanded (9:10), with strong costae dorsally; tergites smooth, with scattered setigerous punctures; base of second tergite with several short costae basally and very short median furrow, subequal to lateral costae; sutures between T2 and T3, T3 and T4 obsolete, remaining sutures deeply impressed.
Colour. Head dark brown except mandibles yellow with reddish tips and antennae yellowish-brown basally gradually darkened towards apex; mesosoma dark brown except tegulae yellow and lower margin of lateral pronotum brown; metasoma brown except petiole dark brown, apical margin of S2 to S6 yellow and T7 and T8 yellowish-brown; legs yellow except hind tibiae and tarsi brown; wings hyaline, covered with brown setae.
Measurements. Head length 0.28 mm, width 0.48 mm; mesosoma length 0.55 mm, width 0.49 mm; metasoma length 0.74 mm; fore wing length 1.48 mm; body length 1.57 mm.
Male (Allotype). Body length 1.56 mm. Similar to female, POL: 7; LOL: 4; OOL: 6; lateral pronotum completely dark brown, metasoma brown except petiole dark brown; median furrow almost absent to extending 0.20 × length of second tergite; radial cell completely closed, 0.6 × as long as length of marginal vein; blade-like carina on A4 percurrent (Fig. 12C); antennal segments in following proportions: 10:3; 5:3; 7:2.5; 7:2.5; 5:2.5; 5:2.5; 4:2.5; 4:2.5; 4:2.5; 4:3; 4:3; 4:3; 4:3; 7:3 (Fig. 12B).
Variation.
Body length 1.31-2.2 mm in both sexes. Paratypes with median furrow very short, subequal to lateral costae to extending 0.20 × length of second tergite in both sexes; colour of T2 brown to partly yellow.
Distribution.
Kenya, Malawi.
