Description. Holotype. ♂. Fore wing length 6.40 mm.

Head. Mandible 1.47 as long as basal width, moderately pilose; ventral margin projected as crest; dorsal tooth distinctly longer than ventral tooth. Clypeus 1.57 as wide as high, subrectangular, finely punctate; apex 1.60 as long as base, truncate; apical margin sharp, medially slightly concave. Supraclypeal area entirely strigate, with scarce punctures, densely pilose, medially with longitudinal subrectangular prominent area; between antennal foramens without V-shaped carina; radicle foveolate. White band starting at flagellomere 8, reaching flagellomere 19; flagellum slender; subapical flagellomeres slightly flattened. Supra-antennal area with stout, median, longitudinal carina, medially without longitudinal elevation, near antennal sockets not striate; dorsal half medially punctulate, or rugulose. Paraocular area finely punctulate. Vertex rugulose around ocelli or with very coarse punctures around ocelli, without sulcus; gena and vertex behind ocelli smooth, sparsely pilose; gena in lateral view at level of dorsal portion of occipital carina narrow, ventrally wide; occipital carina stout, dorsally absent, ventrally markedly projected as crest, reaching hypostomal carina far from mandible base; hypostomal carina projected as crest; malar space 1.03 as long as basal width of mandible.

Mesosoma . Mesosoma in dorsal view 2.05 as long as wide; in lateral view, mesosoma middle width 0.20 mm. Pronotum centrally smooth, latero-ventrally markedly strigate behind collar, margin near mesopleuron ventrally markedly corrugated; pronotal swelling striate; collar dorso-laterally rounded, distinctly swollen, anteriorly punctate; epomia stout, restricted to space between posterior margin of collar and pronotal swelling. Mesoscutum sparsely pilose, lobes dorsally punctulate, laterally markedly corrugated, central lobe with faint longitudinal carina; notaulus moderately impressed, posteriorly abruptly curved, U-shaped. Scutoscutellar groove smooth, polished; scutellum 1.04 as long as wide, smooth; scutellar carina incomplete, restricted approximately to anterior 0.6; postscutellum 0.35 as long as wide; hind margin of metanotum with two lateral teeth. Subalar ridge somewhat rounded; mesopleuron dorsally medially markedly strigate, ventrally strigulate; mesopleural groove corrugated; epicnemial carina faint, dorsally curving backwards; dorsal end of epicnemial carina reaching 0.2 of posterior margin of pronotum, behind epicnemial carina without rounded confused-rugulose area; sternaulus complete, reaching base of mid coxa, markedly sinuate, moderately impressed; faintly corrugated; scrobe very shallow, forming sulcus. Mesothoracic venter punctate and strigulate; median portion of posterior transverse carina of mesothoracic venter short and straight, regularly shaped, without projections. Transverse furrow at base of propodeum laterally 0.16 as long as anterior portion of propodeum deep and narrow, very faintly corrugated, almost smooth, medially some carinae stouter; propodeum 1.11 as long as wide medially; anterior margin of propodeum without teeth; anterior portion of propodeum finely strigulate or with sparse coarse punctures, medially with two parallel longitudinal carinae; lateral longitudinal carina of propodeum indistinct; posterior portion of propodeum entirely markedly strigate, medially with swollen longitudinal carina; anterior transverse carina of propodeum complete, stout, straight; posterior transverse carina absent; propodeal spiracle 2.00 as long as wide; pleural carina of propodeum irregular, fused with sculpture of lower division of metapleuron and propodeum; lower division of metapleuron strigulate, sparsely pilose, juxtacoxal carina short and stout.

Wings. Fore wing: vein 2+3Rs almost straight, apically slightly curved; ramellus absent; vein 1M+Rs entirely sinuous; vein 1cu-a straight, arising far from vein 1M+Rs base, angle with vein M+Cu about 90°; vein 2Cu 0.74 as long as vein 2cu-a; vein 4Rs 0.93 as long as vein 4M, uniformly slightly convex; cell 1+2Rs 0.81 as high as pterostigma, rectangular; vein 2M distinctly longer than vein 3M; vein 3M indistinct. Hind wing: vein 1Cu 1.18 as long as vein cu-a; vein 2-1A reaching 0.77 of distance to posterior margin.

Legs. Tibia with dense short bristles; hind coxa globose.

Metasoma. T1 0.51 as long as hind femur, with basolateral tooth; minutely coriarious; spiracle at anterior 0.53, prominent; postpetiole dorso-anteriorly convex; T2–8 minutely coriarious; centrally almost glabrous, laterally pilose; T2 1.29 as long as wide at apex; apex of T2 2.00 as wide as base.

Color. Head, mesosoma and metasoma black and bright yellow (243,233,146). Head: yellow; mandible apex, clypeal apex centrally, two longitudinal marks extending from anterior tentorial pit to supraclypeal area around medial rectangular swelling, supra-antennal area, interocellar area, vertex and gena, except complete large orbital band, and occiput dorsally, black; scape ventrally yellow, dorsally brown; pedicel and flagellum, brown; flagellum completely whitish at f11–16, partially at f8–10 and f17–19. Mesosoma : mostly bright yellow; pronotum black except collar laterally and pronotal swelling, bright yellow; mesoscutum black, except longitudinal lanceolate mark at posterior 0.9 of central lobe; mesopleuron with three black marks: anteriorly around hypoepimeron, rounded spot just behind epicnemial carina, and at mesopleural groove; remainder of mesosoma bright yellow, except for the following black areas: both axillary trough of mesonotum and metanotum, carinal triangle, anterior portion of propodeum, and three lateral longitudinal marks at propodeum: medially and along pleural carinae. Legs: bright yellow; all t5 dark brown; all femora and hind trochanters, anteriorly and posteriorly, hind tibia, and basal 0.1 of hind t1, brown (124,078,049); fore and mid t1–4 pale brown; mid coxa dorsally with apical lanceolate brown mark; hind coxa with two black marks: posteriorly, reaching basal 0.6, and dorsally, slightly anchor–shaped, reaching apex. Metasoma: black and yellow; T1 laterally bright yellow, dorsally black with posterior 0.2 bright yellow; T2 with lateral and posterior 0.3 bright yellow; T3–8 black with posterior 0.4 bright yellow; S1 bright yellow; S2–8 brownish.

Comments. Color pattern similar to T. coaracius sp. nov. from which it can be readily separated by having anterior transverse carina of propodeum straight (vs. medially markedly arched forwards in T. coaracius sp. nov., Fig. 155 View FIGURES 151–156 ); hind femur entirely brown (vs. yellowish with 0.2 apical black); T1 with basolateral tooth, as in Fig. 53 View FIGURES 45–54. 45 (vs. without basolateral tooth, as in Fig. 54 View FIGURES 45–54. 45 ).

Female. Unknown.

Distribution. Known only from Guyana ( Fig. 218 View FIGURES 216–223 ).

Biology. Unknown.

Material examined. Holotype ♂, GUYANA: Bartica , Kartabo , 5.XI.1920, Tropical Research Station , New York Zoological Society, no. 20972 ( AMNH). Antennae tip missing, mesoscutum somewhat damaged by pin; otherwise in good shape.
