Diagnosis.

This species is distinguished from other species in this genus by males with pubescence twice as long on T1 as on T2 and S8 on both sides with conspicuous bristle of dense, thick, long setae. Females with horizontal part of propodeal triangle defined by sharp transverse carina.

Description.

Holotype. ♂ (SAMA 32-032979), body length 12 mm, head width 3.3 mm.

Relative head measurements. HW 50, HL 42, UID 31, UFW 34, LID 28, DMA 30, HVO 2, WOC 17, MOD 3, OOD 7, IAD 8, ASD 3, AOD 8, ML 21, BMW 6, MSL 1, SL 14, SW 3, FL 61,

Structure. Head: face longer than wide, clearly converging below; malar space circa 0.16 × basal mandibular width; clypeus protuberant, vertex not elevated; gena little wider than 0.7 eye width viewed laterally; flagellum 1.22 × head width; flagellomeres 2-5 1.6 × as long as wide; flagellomere 11 2.3 × as long as wide. Legs not modified: hind tarsus about as long as hind tibia; hind basitarsus 5.5 × as long as wide; hind coxa with posterior ventral procession; S7 (Fig. 4C), inner lobes almost straight; S8 (Fig. 4D) bare at apex, both sides with conspicuous bristle of dense thick long setae, apparent in un-dissected specimens; genital capsule (Fig. 4 A–B): penis valves progressively broadened from mid of gonocoxite to base of gonostylus.

Coloration. Integument black, apart from antenna ventrally, legs orange, apart from femur of front leg and posterior part of femur of middle leg black, tegula brown, marginal zone of T1-6 transparent.

Sculpture. Scutum, propodeum and tergites with close pit-reticulation, vertical part of propodeal triangle dull with fine irregular reticulation, horizontal part with radial striae, lateral rim coarsely areolate.

Pubescence. Eyes with tiny dispersed hairs. Pubescence orange, apart from posterior margin of T6 and whole of T6-7 black, genae near margin of eye pale orange. Hairs on face erect dense and long, hairs on T1 dense, much longer than on T2-4. Sternites almost bare, apart from S3-4 with narrow dense posterior fringes.

Paratype. ♀ (SAMA 32-033292), body length 13 mm, head width 3.8mm.

Relative head measurements. HW 50, HL 45, UID 29, UFW 35, LID 30, DMA 29, HVO 2, WOC 16, MOD 3, OOD 6, IAD 8, ASD 3, AOD 9, ML 23, BMW 8, MSL 3, SL 16, SW 3, FL 32.

Structure. Head: inner eye margin straight converging below; scape over reaching median ocellus, tapering basally; malar space smooth length about 0.16x width; labial palps reaching beyond apex of extended glossa; maxillary palps reaching beyond apex of extended glossa; clypeus below level of supraclypeus; epistomal suture distinct, almost straight; labrum basally strongly produced, apically flat and smooth; F3-10 length equal to, or less than width, F1 longer than F3; antennal sockets depressed; supraclypeal area strongly raised above frons level; midtibial spur long, robust; inner hind tibial spur with 7 long, slender teeth. Metasoma: marginal zones of tergites with weaker sculpture than on disc; pygidial plate broadly rounded apically, flat, dull; T2-4 almost entirely close punctated.

Coloration. Head: integument black with dark brown to black clypeus; mandibles black, brown and smooth medially; scape almost naked, black; flagellum; light brown beneath, dark brown above. Mesosomal integument black. Metasomal integument orange.

Sculpture. Scutum and scutellum medially smooth with strong open punctation; metanotum dull and rugose; propodeal triangle with several transverse sharp carinae, basal area narrower than metanotum; Vertex closely and medium size punctated over entire width; clypeus flat, shiny with open large punctures; supraclypeal area polished, flat.

Pubescence. Head - hair white, densest on the lower paraocular area; mesosomal hair white; hind basitibial plate with dense, fine hair apparently not branched, not obscuring marginal carina; hind basitarsus with posterior fringe of dense long branched white hair widest anteriorly. Metasomal hair dorsally short, sparse; prepygidial fimbria black; T2-4 with fringes of long white hair.

Months collected.

January, March, November.

Floral visitations.

Eucalyptus ( Myrtaceae ), Melaleuca ( Myrtaceae ), Myoporum ( Myoporaceae ).

Distribution.

Known from seven localities in southern Australia, east and west of the Nullarbor Plain.

Etymology.

The species is named after Stan Wann, the grandfather of the co-collector, Beth Tully. Stan Wann grew up in the bush on the north coast of NSW, and had a profound knowledge of the birds and trees in the area.
