Diagnosis

Female with large protuberance on vertex and stiff, pale orange setae across frons ( Fig. 6). Male with slight projection on vertex, hind tibia with two large, almost straight spurs. Both sexes have mandibles with a prominent outer ridge and no preapical tooth.

Descriptions

Male.— Head width 1.9 mm, body length 5.7 mm. Relative measurements: HW 50, HL 44, UID 34, UFW 30, LID 23, HVO 0.7, WOC 19, OOD 9, IAD 8, AOD 6, SL 14, SW 4, FL 34. Vertex of head weakly elevated medially; inner orbits strongly convergent ventrally; clypeus almost flat basally, gently convex on apical quarter; antennal sockets level with front of eye viewed laterally; mandible simple with prominent outer ridge; labrum basally, convex with medial depression, apically concave; flagellum 0.68× as long as head width; metanotum with weak nodule; propodeal triangle subhorizontal basally, separated abruptly from vertical half but not carinate. Hind femur almost flat ventrally; hind tibia moderately broad, maximum width 0.27× length, bearing 8 stiff, apically bent setae, the most distal being particularly large and flattened ( Fig. 12); hind tibial spurs large, almost straight, inner distinctly pectinate, outer 0.75× as long as inner; hind basitarsus dished, width 0.40× length, with small apical extension of anterior margin. Metasomal T2 with postgradular area weakly depressed; S6 with polished medial ridge; S7,8 and genitalia as in Figs. 24–26 View Figures 21–35 .— Integument black except flagellum brown, mandibles orange-brown with dark red tips, anterior face fore tibia and fore tarsus yellow-brown, mid and hind tarsi dark brown, metasomal terga dark brown or black with posterior margins translucent brown, sterna dark brown or black.— Clypeus densely punctate, supraclypeal area medially impunctate and polished; frons with strong, dense, medium punctures, fovea obscured by tomentum; scutum and scutellum polished and closely 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, white setae between ocelli, weakly branched laterally; gena with open, white, plumose hair; scutum and scutellum openly covered with white, finely plumose hair, longer around margin of scutellum; metanotum with similar long hair medially; metasomal T1 with open, long, white hair on basal half, T1,2 with white hair apicolaterally (possible basal hair bands hidden), hair sparse elsewhere; S3,4 with long apical fringes, S6 with dense apical tuft.

Female— Head width 2.3 mm, body length 7.2 mm. Relative measurements: HW 50, HL 43, UID 36, UFW 34, LID 26, HVO 4, WOC 17, OOD 10, IAD 8, AOD 8, SL 16, SW 3, FL 23. Vertex of head with large medial protuberance ( Fig. 6), inner orbits convergent ventrally; clypeus flat except at extreme ventrolateral corners, apical margin straight with minute medial projection; mandible with prominent outer ridge and no preapical tooth; labrum strongly carinate, basally and apically concave; flagellum less than ½ as long as head width; metanotum and propodeum as for male. Hind basitibial plate carinate, apex bluntly acute; inner hind tibial spur gently curved with ca 10 strong teeth; pygidial plate emarginate.— Integument black except labrum and flagellum brown, mandibles amber with dark red tips, metasomal terga with posterior margins translucent brown; sterna dark brown.— Clypeus dull, densely punctate, except ventrolateral corner impunctate and polished; interantennal area with small impunctate region; frons and vertex densely punctate; fovea slightly narrower than base of scape not reaching lateral ocellus; scutum and scutellum densely punctate; metanotum with fine contiguous punctures; propodeal triangle irregularly rugose basally, propodeum laterally with dense round punctures; metasomal terga polished and densely punctate except on posterior margins; sterna with punctures sparse basally becoming dense apically; pygidial plate coarsely striate.— Face with small area of dense, white pubescence in paraocular area to just above antennal sockets; vertex and frons with close, stiff, pale orange setae; clypeus with close, fine simple hair; scutum and scutellum closely covered with short, densely-branched, cream hair, becoming dense around margins; metanotum with slightly longer hair near tubercle; hind tibial scopa white; hind basitarsus with open fringe of long white plumose hair on posterior margin; metasomal T1 with dense white hair apicolaterally, T2–4 with close white hair bands basally and broad, dense white hair bands apically, interrupted medially on T2; prepygidial fimbria white; S5 with dense, white apical fringe.

Remarks. The sexes were associated by the protruding vertex and coincident collection.

Etymology. The specific name is a Latin noun in apposition meaning hump, referring to the vertex of the female.
