This species is distinguished from other species in this genus by males with black metasoma, simple orange legs with brown coxae and trochanters, scape black, pubescence on T1 as long as on T2 and S8 with evenly and openly placed long radiating setae. Females with propodeal triangle gradually sloping downwards, horizontal area not defined by a sharp carina.


Holotype: Male (SAMA 32-032610), body length 8.8 mm, head width 2.6 mm.

Relative head measurements. HW 50, HL 42, UID 30, UFW 33, LID 27, DMA 28, HVO 0, WOC 15, MOD 4, OOD 8, IAD 8, ASD 3, AOD 7, ML 21, BMW 8, MSL 1, SL 13, SW 3, FL 52.

Structure. Head: face longer than wide, clearly converging below; malar space circa 0.13 × basal mandibular width; clypeus protuberant; vertex not elevated; gena about 0.8 × eye width viewed laterally; flagellum as long as head width; flagellomeres 3-11 1.4 × as long as wide. Legs not modified: hind tarsus longer than hind tibia; hind basitarsus 7 × as long as wide; hind coxa without posterior ventral procession; S7 (Fig. 3C), inner lobes almost straight broadly rounded proximally; S8 (Fig. 3D) with evenly and openly placed long radiating setae, apparent in un-dissected specimens; genital capsule (Fig. 3AB), penis valves suddenly broadened at level of mid gonocoxite.

Coloration. Integument black, apart from antenna ventrally brown, legs orange, apart from basis of femur of front and middle legs, all coxae and trochanters brown, tegula translucent orange; 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 transverse 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 eye margin whitish. Hairs on face erect, dense and long; hairs on T1 longer than on T2-4; sternites almost bare, apart from S3-4 with narrow, dense posterior fringes.

Female (SAMA 32-033291), body length circa 11 mm, head width 3.2 mm.

Relative head measurements. HW 50, HL 40, UID 28, UFW 34, LID 29, DMA 27, HVO 1, WOC 16, MOD 4, OOD 6, IAD 8, ASD 3, AOD 8, ML 21, BMW 7, MSL 2, SL 15, SW 3, FL 33.

Structure: Head: inner eye margin straight, converging below; scape reaching median ocellus, tapering basally; malar space smooth length about 0.16 width; labial palps and maxillary palps just reaching apex of extended glossa; clypeus below supraclypeal level; epistomal suture distinct, almost straight; labrum basally strongly produced, apically flat; F1,3-10 length equal to, or less than width, F2 shorter than width; antennal sockets depressed; supraclypeal area strongly raised above frons level; midtibial spur long, slender; inner hind tibial spur with 6 long, slender teeth (other examined specimens with 7 teeth); Metasoma: postgradular area with weaker sculpture than pregradular area; pygidial plate broadly rounded apically, flat, dull; T2-4 anteriorly fine reticulate striated, posteriorly open to close punctated.

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

Sculpture: Scutum and scutellum posteriomedially smooth with strong open punctation; metanotum dull and rugose; propodeal triangle with several fine transverse carina, anterior area narrower than metanotum; anterior area almost smooth. Clypeus flat, shiny with open large punctures; supraclypeal area polished, flat.

Pubescence: Head: hair white, dense on lower paraocular area; mesosomal hair white; hind basitibial plate with dense, branched hairs, obscuring marginal carina; hind basitarsus with posterior open fringe of long, branched grey hairs. Metasomal hair dorsally short, sparse, white; prepygidial fimbria dark brown; T2-4 posteriorly with fringes of long white hair.


A redescription of this species was necessary because the specimens examined under Maynard’s (2013) original description of Goniocolletes comatus , appear to belong to more than one species. The male holotype and the female are redescribed for comparative reasons.
