 Leioproctus (Excolletes) impatellatus * Michener 1965: 251   
 Types   
 Leioproctus (Excolletes) impatellatus — NEW SOUTH WALES: holotype ♀, 95 miles (152k) N Tibooburra, 3.xi.1949, S.J. Paramonov (ANIC); " allotype " (= paratype), ♂, same data as holotype (ANIC), paratype, 1♂, Clifton Downs, 31.x.1949, S.J. Paramonov (ANIC).   
The species name on the labels of the types is incorrect—it is written as "apatellus" not "impatellatus" (the published name). Many more specimens are now known.  
 Additional material examined: 30♀, 2♂ Queensland: 15km W Windorah. Northern Territory: 34km E Curtin Springs.   
 Months collected: September, October, November, December.   
 Floral visitations: Proteaceae: Grevillea; Myrtaceae: Corymbia terminalia.   
  Female —  Length ca 7mm; integument dark brown to black with white hair; Small, dark, non-metallic bees; antennal bases on lower half of the face. Head —Vertex rounded above ocelli; facial foveae vaguely indicated by change in surface texture, usually totally obscured by hair; frons flat with dense, small strong punctures and polished interspaces; inner eye margins converging at ocellar level and at malar area; antennal sockets on lower half of face depressed; frontal line carinate on lower half; scape not reaching median ocellus; flagellar segments all the same length; supraclypeal area not raised, medially glabrous; epistomal suture and subantennal suture absent, anterior tentorial pit only vaguely indicated; central half of clypeus sparsely haired and punctate ventral margin with 1–2 long, thick hairs; labrum polished convex subrectangular area; malar space absent; mandibles with large apical tooth and distinct pollex; apical three segments of maxillary palps extending beyond the apex of extended glossa; apex of glossa truncate, with long apical fringe; basal labial palp segment flattened, apical 2 segments shorter than basal 2 segments, not extending beyond the apex of extended glossa; gena narrower than eye width when head viewed laterally. Mesosoma —Scutum and scutellum polished with a few sparse punctures and laterally with short, dense marginal fringe; metanotum very narrow, convex, polished with a few, sparse hairs; propodeal triangle polished, basal area twice length of metanotum and longer than vertical area; area immediately lateral to propodeal triangle polished with a few sparse hairs; lateral margins of propodeal triangle foveolate. Fore wing with large pterostigma, more than 0.5 x length of costal margin of marginal cell; apex of marginal cell strongly divergent from costa for at least 0.2 x length of the costal marginal cell; first recurrent vein enters second submarginal cell towards the apex; wings almost hairless in veined area; membrane clear; jugal lobe of hind wing reaching beyond cu-a. Legs with paler brown apical segments; fore tibia spur with apex of malus almost as long as velum and a few fine teeth at base of spine; tarsomeres with long, fine, simple hairs dorsally; midtibial spur very long, fine and poorly sclerotised; hind basitarsus with long, posterior, simple fringe; hind basitibial plate lacking marginal carina, covered by pale brown hair; hind basitibial plate absent, hair of dorsal surface of tibial scopa almost palmate with 4, long, branches from median shaft of the hair; inner hind tibial spur without large teeth, ciliate; claws with or without an inner ramus. Metasoma —Integument brown T1–4 with dense, small, weak punctures with minutely granular interspaces; T2–3 with dense, apical band of hair broadly interrupted medially; T5 completely covered by a dense, pale brown prepygidial fimbria; pygidial plate constricted just above the base to a narrow, somewhat spatulate plate, bluntly rounded apically; T6 with dense pale yellow hair either side of the plate; S2 with broad apical band of moderate length hair that is weakly branched; S3–6 with narrow, apical band of simple hair.  Male —  As for female except as follows: Length ca 5mm. Head— All flagellar segments with length about equal to width; dorsal tooth broadly separated from apical tooth (resembling a can opener). Mesosoma —Hind bastibial plate small, but clearly defined; all claws with an inner ramus. Metasoma— Apical bands absent; covered in mostly short appressed hair; apical margins vaguely translucent; T7 denudate; apical lobes of S7 broadly joined; S8 strongly protuberant; sterna covered in fine, sparse hair; for S7–8 and genitalia see figs 115–117.
