Descriptions

Male.— Head width 1.9 mm, body length 5.6 mm. Relative measurements: HW 50, HL 41, UID 32, UFW 32, LID 23, HVO 1, WOC 20, OOD 7, IAD 10, AOD 6, SL 13, SW 4, FL 34. Inner orbits strongly convergent ventrally; face convex, antennal sockets in front of eye viewed laterally; clypeus transversely convex; basal part of labrum convex with small medial depression, apical part concave, less than half as long as basal part; flagellum 0.68× as long as head width; metanotum with weak tubercle; propodeal triangle subhorizontal basally, vertical apically with a sharp change of slope but no carina. Hind tibia slender ( Fig. 13), maximum width 0.22× length, with 6 stiff setae; hind tibial spurs large, almost straight, outer 0.85× as long as inner; hind basitarsus dished, width 0.30× length, with small, spathulate, projection from distal end. Metasomal T2 with postgradular area depressed; S6 with very weak medial ridge; S7,8 and genitalia as in Figs. 27–29 .— Integument black except flagellum brown, mandibles orange-brown with dark red tips, labrum dark brown basally, orange-brown apically, metasomal terga with posterior margins translucent brown, sterna dark brown, anterior face fore tibia and fore tarsi yellow-brown, mid and hind tarsi brown.— Clypeus densely punctate; supraclypeal area dull, punctate; frons with strong, dense, medium punctures, fovea obscured by tomentum; scutum and scutellum polished, closely to openly punctate; mesepisternum densely punctate; metanotum with fine contiguous punctures; propodeal triangle coarsely rugose basally, laterally propodeum densely punctate; metasomal terga densely punctate except for wide impunctate apical margins.— Face densely covered with adpressed, silverwhite pubescence; vertex with close, erect, plumose, white hair; gena with similar hair; scutum and scutellum openly covered with long, finely plumose, white hair, longer and denser around margins; metasomal T1 with open, long, white hair on basal half, T1,2 with dense, white hair apicolaterally, T3,4 with sparse, white apical hair bands, T2–4 with bands of close white hair basally; S3,4 with long apical fringes; S6 with weak apical hair tuft.

Female— Head width 2.3 mm, body length 7.5 mm. Relative measurements: HW 50, HL 42, UID 34, UFW 35, LID 25, HVO 1, WOC 21, OOD 7, IAD 9, AOD 8, SL 14, SW 3, FL 25.— Inner orbits convergent ventrally; face convex, antennal sockets in front of eyes viewed laterally; clypeus convex with convex apical margin; labrum strongly carinate, basally convex with a large medial depression, apically concave; mandible narrow with preapical tooth and weak, rounded outer ridge; flagellum ½ as long as head width; metanotum and propodeum as for male. Hind basitibial plate strongly carinate, apically rounded; inner hind tibial spur gently curved with 5 well-spaced teeth; pygidial plate striolate, apex rounded, entire.— Integument black except flagellum brown, mandibles amber with dark red tips, labrum brown basally, apically amber; metasomal terga with posterior margins translucent brown, sterna black or dark brown, anterior face fore tibia yellow-brown.— Clypeus, interantennal area, frons and vertex densely punctate; fovea strongly impressed, impunctate, ca ⅔ width of scape basally, curving towards but not reaching lateral ocellus; scutum and scutellum densely punctate; metanotum with fine contiguous punctures; propodeal triangle irregularly rugose basally, propodeum laterally densely punctate; metasomal terga polished and densely punctate except on posterior margins; sterna with punctures sparse basally becoming dense apically; pygidial plate striolate.— Face with dense, adpressed, white pubescence in paraocular areas almost reaching top of eye; vertex with a row of ca 12 pale orange, erect, curved setae ( Fig. 7); frons and clypeus openly covered with finer, unbranched setae; scutum and scutellum closely covered with short, densely-branched, erect, white hair, becoming dense around margins; metanotum with slightly longer hair near tubercle; hind tibial scopa white, sparsely branched; hind basitarsus with open fringe of long white plumose hair on posterior margin; metasomal T1,2 with dense white hair apicolaterally, T3,4 with broad, dense white apical hair bands, T2–4 basally with close white hair bands, usually obscured by preceding tergum; prepygidial fimbria pale brown; S5 with dense, white apical fringe.

Remarks. The sexes were associated by coincident collection and the convex face.

Etymology. The species is named after Alex Gurney, creator of the comic strip “Bluey and Curley”.
