( Figure 13 )

Material examined

Holotype. Female , South Africa, “E. Cape Prov., Katberg, xii.1932, 4000ft ” ( BMNH).

Morphology

Length of body 7.3 mm, and of fore wing 7.8 mm. Head. Antenna with 61 flagellomeres; terminal flagellomere acuminate; head transverse, 1.5 times wider than maximally long in dorsal view; width of head 2.6 times shortest distance between eyes; face with fine transverse striation laterally and with mid-longitudinal striation medially; height of eye 1.7 times shortest distance between eyes; frons weakly depressed, smooth and shiny without pit in front of anterior ocellus; posterior ocellar line: transverse diameter of posterior ocellus: shortest distance between posterior ocellus and eye = 2.6: 4.4: 1.0. Area between stematicum and eyes crenulated; occiput coriaceous-rugulose; occipital carina broadly obliterated medially.

Mesosoma . Mesoscutum coarsely coriaceous becoming rugulose-coriaceous posteriorly and densely short-setose and with conspicuous punctures at bases of setae; notauli weak, margined on inner side by fine ridge and with distinct line of crenulae; mesopleuron densely setose and smooth and shiny between setae, without depression; prepectal carina complete; scutellar sulcus with six carinae between the outer ones; scutellum finely aciculate and with large, ovoid punctures at bases of setae; median area of metanotum virtually smooth and shiny; propodeum largely irregularly foveate-rugulose with complete mid-longitudinal carina.

Fore wing. Subbasal cell setose on basal 0.8, weakly narrowed before largely glabrous distal part which contains a setose sclerome connected by band of setae to basal setose area but not to vein cu-a; vein 1-1A with a broad, tranverse, posteriorly-directed spur approximately at its mid-point; vein 1-CU1 0.31 times length of 2-CU1; vein cu-a approximately vertical, hardly curved, weakly expanded posteriorly; length of veins r: 3-SR: SR1 = 1.0: 2.6: 5.0; vein 2-M 2.8 times length of r-m; vein m-cu 1.7 times length of 2-SR+M, forming angle of 100 ◦ with 3-CU1.

Hind wing. Vein M+CU 1.05 times length of vein 1-M; vein 2-SC+R distinctly longitudinal; basal and subbasal cells and basal part of discal+subdiscal cell evenly setose.

Claws. With pecten of four strong teeth reaching just beyond middle of basal lobe.

Metasoma. Tergites 1, 2 and basal half of tergite 3 finely longitudinally striate with irregular punctures between the striae; 2nd tergite 1.1 times wider than medially long, 1.55 times longer than 3rd.

Colouration

Antenna black. Head including palps yellow with face brown and frons, vertex and occiput brown-black. Mesosoma black with tegulae, sides of scutellum, metanotum and most of propodeum yellow. Fore and middle legs yellow except mid tibia and tarsus brown-black; hind leg black except trochanter and trochantellus yellow. Wings yellow with apex of fore wing beyond pterostigma brown with a large clear window distal to vein r-m, and hind wing with brown-grey apex with pale patch at middle of apex.

Etymology

Named after the junior author’s friend Lorna Fadden.
