Description. Holotype FEMALE. Fore wing length 7.10 mm.

Clypeus 1.76 as wide as high, subrectangular, minutely strigulate, apically smooth; apex 1.76 as long as base, truncate; apical margin blunt, medially straight. Supraclypeal area medially strigate, laterally finely punctate, moderately pilose, medially slightly prominent; between antennal foramens without V-shaped carina; radicle foveolate. Antenna with 28 flagellomeres; white band starting at flagellomere 5, reaching flagellomere 15; flagellum slender; subapical flagellomeres as wide as basal flagellomeres, not flattened. Supra-antennal area with stout, median, transversally arched, medially interrupted carina, medially with slightly longitudinal elevation, near antennal sockets not striate; dorsal half medially rugulose. Paraocular area finely strigulate. Vertex rugulose around ocelli, without sulcus; gena and vertex behind ocelli with scarce punctures, sparsely pilose; gena in lateral view at level of dorsal portion of occipital carina narrow, ventrally wide; occipital carina faint, dorsally absent, ventrally markedly projected as crest, reaching hypostomal carina at mandible base or nearly so; hypostomal carina projected as crest; malar space 0.81 as long as basal width of mandible.

Mesosoma . Mesosoma in dorsal view 2.00 as long as wide; in lateral view, mesosoma middle width 0.23 mm. Pronotum centrally corrugated, latero-ventrally markedly strigate behind collar, margin near mesopleuron ventrally markedly corrugated; pronotal swelling strigulate; 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 sparse coarse punctures, central lobe with faint longitudinal carina; notaulus moderately impressed, posteriorly abruptly curved, U-shaped. Scutoscutellar groove faintly corrugated; scutellum 1.03 as long as wide, scarcely punctate; scutellar carina incomplete, restricted approximately to anterior 0.3; postscutellum 0.28 as long as wide; hind margin of metanotum without teeth or carinae. Subalar ridge somewhat elongate; mesopleuron entirely markedly strigate; mesopleural groove corrugated; epicnemial carina stout, dorsally straight; dorsal end of epicnemial carina reaching 0.2 of posterior margin of pronotum, behind epicnemial carina without rounded confused-rugulose area; sternaulus medially shallow, interrupted, reaching base of mid coxa, markedly sinuate, deeply impressed; faintly corrugated; scrobe deeply impressed, forming pit. Mesothoracic venter coarsely punctate; median portion of posterior transverse carina of mesothoracic venter long and straight, regularly shaped, without projections. Transverse furrow at base of propodeum laterally 0.15 as long as anterior portion of propodeum deep and narrow, medially wide, closely corrugated, medially some carinae distinctly stouter; propodeum 1.14 as long as wide medially; anterior margin of propodeum without teeth; anterior portion of propodeum strigate or with sparse coarse punctures, medially without longitudinal carinae; lateral longitudinal carina of propodeum represented by subcircular carina; posterior portion of propodeum confused-rugose, medially without distinctly stout longitudinal carina; behind posterior transverse carina with two divergent longitudinal carinae; anterior transverse carina of propodeum complete, stout, medially arched backwards; posterior transverse carina absent; propodeal spiracle 1.89 as long as wide; pleural carina of propodeum irregular, fused with sculpture of lower division of metapleuron and propodeum; lower division of metapleuron strigate or sparsely punctate, sparsely pilose, juxtacoxal carina short and stout.

Wings. Fore wing: vein 2+3Rs almost straight; ramellus absent; vein 1M+Rs uniformly curved; vein 1cu-a posteriorly slightly curved, arising far from vein 1M+Rs base, angle with vein M+Cu distinctly obtuse; vein 2Cu 0.64 as long as vein 2cu-a; vein 4Rs 1.02 as long as vein 4M, uniformly slightly convex; cell 1+2Rs 0.96 as high as pterostigma, rectangular; vein 2M distinctly longer than vein 3M; vein 3M distinct, 0.67 as long as vein 2M. Hind wing: vein 1Cu 1.85 as long as vein cu-a; vein 2-1A reaching 0.85 of distance to posterior margin.

Legs. Tibia with very sparse short bristles; hind coxa globose.

Metasoma. T1 0.47 as long as hind femur, with faint basolateral tooth; minutely coriarious; spiracle at anterior 0.56, slightly prominent; postpetiole dorso-anteriorly flat; T2–8 minutely coriarious; almost glabrous; T2 1.02 as long as wide at apex; apex of T2 1.89 as wide as base. Dorsal valve of ovipositor with nodus indistinct; apex of lower valve with series of teeth; notch present.

Color. Head, mesosoma and metasoma black with yellow marks (244,223,107). Head: black; mouthparts, malar space dorsally, clypeus laterally, supraclypeal area laterally, paraocular area interrupted centrally, and genal orbit dorsally, bright yellow (240,222,135); mandible, clypeus apically, scape, pedicel and flagellum, dark brown (097,055,030); flagellum dorsally entirely whitish at f5–11, partially at f12–14. Mesosoma : black; lateral small mark at collar, pronotal swelling, longitudinal lanceolate mark at posterior 0.3 of central lobe of mesoscutum, axillary carina, scutellum, postscutellum, tegula basally, upper division of metapleuron, large mark at dorsal half of lower division of metapleuron, and hind margin of metanotum, bright yellow; mesopleuron with three small bright yellow spots: at subalar ridge, dorsal half of hypoepimeron, and dorsally to epicnemial carina; posterior portion of propodeum with two lateral longitudinal large yellow stripes. Legs: all coxae dark brown with yellow (225,165,099) spots; fore and mid coxae with small dorsal yellow spot; hind coxa with two yellow spots, the large one dorsal, at basal 0.7, the small one lateral, at basal 0.2; first trochanter of all legs apically yellow; fore and mid femora dark yellow, ventrally brown (118,093,074); hind femur dark brown, with dorsal narrow yellow stripe; all tibiae and tarsi yellow, except for all t5, apical 0.3 of hind tibia, and basal 0.3 of t1, dark brown. Metasoma: black; T1–T8 bright yellow at posterior 0.2.

Comments. Very similar to T. teutonius sp. nov., from which it is isolated by having sternaulus medially shallow, interrupted (vs. complete in T. teutonius sp. nov.); anterior transverse carina of propodeum medially arched backwards (vs. straight; Fig. 145 View FIGURES 145–150 ); hind femur dorsally with narrow yellow stripe (vs. entirely black); apical 0.3 of hind tibia dark brown (vs. hind tibia entirely yellow); metasoma striped (vs. entirely black).

Male. Unknown. Distribution. Known only from Suriname ( Fig. 231 View FIGURES 224–231 ). Biology. Unknown. Material examined. Holotype ♀, SURINAME: 45 Km S Paramaribo, 29.IX.1963, D.C. Geijskes leg. ( AEIC). Left antenna tip, and right fore leg beyond coxa, missing; mesoscutum somewhat damaged by pin; otherwise in good shape.
