Diagnosis

Males with flagellum longer than head width, hind basitarsus with large apical projection and hind tibia with weak setae. Female frons and clypeus closely covered with erect, weaklybranched, curly hair. The labrum of both sexes smoothly convex.

Descriptions

Male.— Head width 2.1 mm, body length 6.8 mm. Relative dimensions: HW 50, HL 46, UID 39, UFW 36, LID 30, HVO 3, WOC 21, OOD 10, IAD 8, ASD 5, AOD 7, SL 18, SW 5, FL 71.— Inner orbits strongly convergent ventrally; clypeus transversely convex, longitudinally almost flat; labrum smoothly convex; flagellum longer than head width; metanotum with weak nodule; propodeal triangle subhorizontal basally, rounding smoothly onto vertical half. Hind tibia slender, maximum width 0.22× length, bearing 7 stiff setae, weaker than those of other species and inclined apically; hind tibial spurs large, weakly recurved, outer 0.83× as long as inner; hind basitarsus flat, narrow, width 0.25× length, with large distal projection on anterior margin ( Fig. 11). Metasomal T2 with postgradular area weakly depressed; S6 with polished medial ridge; S7,8 and genitalia as in Figs. 21–23 .— Integument black except flagellum brown becoming orange-brown towards apex, mandible orange-brown with dark red tip, anterior faces of fore and mid tibia and inner faces fore and mid tarsi yellowbrown, tarsi with outer faces brown, metasomal terga with posterior margins translucent brown, sterna dark brown.— Clypeus densely punctate, supraclypeal area impunctate, polished; frons with strong, dense, medium punctures, fovea not impressed; scutum, scutellum and mesepisternum strongly and densely punctate, polished; metanotum with fine contiguous punctures; propodeal triangle coarsely rugose basally, propodeum laterally with large, contiguous punctures; metasomal terga strongly punctate except wide apical margins.— Face below mid frons densely covered with adpressed, silver-white pubescence; vertex with close, pale brown, erect, plumose hair; gena with similar white hair; scutal hair long, open, white and finely plumose; scutellum and metanotum with long, sparse, pale brown, finely plumose hair, denser around margins; metasomal T1 with long, open, white hair on basal half, T1,2 with white hair apicolaterally, T2–4 with broad basal bands of close white hair; S3,4 with long apical fringes, slightly shorter medially, S6 with weak fringe around apex but no apical tuft.

Female.— Head width 2.3 mm, body length 7.5 mm. Relative measurements: HW 50, HL 46, UID 38, UFW 40, LID 33, HVO 2, WOC 19, OOD 10, IAD 9, ASD 4, AOD 9, SL 16, SW 4, FL 27.— Inner orbits convergent ventrally; clypeus transversely convex, base protruding in front of eye viewed laterally; labrum uniformly convex, smooth and polished ( Fig. 5); mandible narrow with weak, rounded outer ridge; flagellum 0.54× as long as head width; metanotum with weak nodule; propodeum subhorizontal basally, rounding smoothly onto vertical half. Hind basitibial plate carinate, apically rounded; inner hind tibial spur with ca 5 wellspaced teeth; pygidial plate emarginate.— Integument black except flagellum brown, mandible amber with dark red tip, tibiae and tarsi with interior faces brown, metasomal terga with posterior margins translucent brown.— Clypeus polished, densely punctured except apically and along medial line; supraclypeal area impunctate, polished; frons with smaller contiguous punctures; fovea weakly impressed with indistinct margins, impunctate and dull, reaching lateral ocellus, as wide as basal width scape; scutum and scutellum densely punctate; metanotum with fine contiguous punctures; propodeal triangle coarsely rugose basally, propodeum laterally with dense, round punctures; metasomal terga polished, densely punctate except on broad posterior margins; sterna with punctures sparse basally becoming dense apically; pygidial plate not striate, but with fine, whorled lineolation like a fingerprint.— Face with small area of dense, plumose, white pubescence between antennal socket and eye margin; frons and clypeus closely covered with weakly-branched, erect, fine, curly hair ( Fig. 5); vertex sparsely covered with weakly-branched, straight hair; scutum and scutellum closely to densely covered with very short, tightly-branched brown hair, becoming paler and longer around margins; mesepisternum closely covered with long, white, plumose hair; hind tibial scopa white; hind basitarsus with fringe of long white plumose hair on posterior margin; metasomal T1 with dense white hair apicolaterally, T2–4 with close white hair bands basally (usually obscured by preceding tergum) and broad, dense, white, apical hair bands, interrupted medially on T2; prepygidial fimbria brown; S5 with dense, pale brown apical fringe.

Remarks. The sexes were associated by the shape of the labrum. A male and 3 females were taken in a single pan trap left in place for six hours, and specimens from the Charleville area were collected within days and a few kilometres of each other.

Etymology. The specific name is a Latin adjective meaning curly, referring to the facial hair of the female.
