Description. Holotype FEMALE. Fore wing length 6.32 mm.  
 Head. Mandible 1.63 as long as basal width, almost glabrous; ventral margin projected as crest; dorsal tooth distinctly longer than ventral tooth. Clypeus 1.95 as wide as high, rectangular, finely punctate, apically smooth; apex 1.54 as long as base, truncate; apical margin sharp, medially slightly concave. Supraclypeal area entirely strigulate, also densely punctate, moderately pilose, medially with longitudinal subrectangular prominent area; between antennal foramens with V-shaped carina, medially interrupted; radicle foveolate. Antenna with 25 flagellomeres; white band starting at flagellomere 3, reaching flagellomere 19; flagellum slender; subapical flagellomeres as wide as basal flagellomeres, not flattened. Supra-antennal area with stout, median, longitudinal carina, medially with slightly longitudinal elevation, near antennal sockets not striate; dorsal half medially rugulose. Paraocular area finely punctulate. Vertex rugulose between ocelli, at anterior third with short, longitudinal sulcus, posterior two-thirds smooth; gena and vertex behind ocelli smooth, sparsely pilose; gena in lateral view uniformly narrow; occipital carina stout, dorsally V-shaped, ventrally markedly projected as crest, reaching hypostomal carina at mandible base or nearly so; hypostomal carina projected as crest; malar space 0.97 as long as basal width of mandible.   
 Mesosoma. Mesosoma in dorsal view 1.89 as long as wide; in lateral view, mesosoma middle width 0.22 mm. Pronotum centrally smooth, latero-ventrally smooth, margin near mesopleuron entirely corrugated; pronotal swelling smooth; collar dorso-laterally rounded, distinctly swollen, anteriorly smooth; epomia very faint, almost indistinct. Mesoscutum sparsely pilose, densely punctate, impression of notaulus corrugated, central lobe without longitudinal sulcus or carina; notauli deeply impressed, posteriorly abruptly curved, U-shaped. Scutoscutellar groove markedly corrugated; scutellum 0.88 as long as wide, smooth; scutellar carina incomplete, restricted approximately to anterior 0.30; postscutellum 0.26 as long as wide; hind margin of metanotum without teeth or carinae. Subalar ridge somewhat rounded; mesopleuron dorsally medially strigate, ventrally strigulate; mesopleural groove corrugated; epicnemial carina stout, dorsally straight; dorsal end of epicnemial carina reaching 0.10 of posterior margin of pronotum, behind epicnemial carina without rounded confused-rugulose area; sternaulus complete, reaching base of mid coxa, markedly sinuate, deeply impressed; markedly corrugated; scrobe moderately deep, forming pit with sulcus. Mesothoracic venter strigulate; median portion of posterior transverse carina of mesothoracic venter V-shaped, expanded as two deltaic perpendicular projections. Transverse furrow at base of propodeum laterally 0.27 as long as anterior portion of propodeum, shallow and wide, markedly corrugated; propodeum 1.01 as long as wide medially; anterior margin of propodeum without teeth; anterior portion of propodeum strigate, medially with two parallel longitudinal carinae; lateral longitudinal carina of propodeum represented by subcircular carina; posterior portion of propodeum confused-rugose, medially with two stout longitudinal carina; behind posterior transverse carina with two stout parallel longitudinal carinae; anterior transverse carina of propodeum complete, stout, medially markedly arched forwards; posterior transverse carina represented by blunt apophysis, present laterally as carina; propodeal spiracle 1.47 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, densely pilose, juxtacoxal carina long and stout.   
 Wings. Fore wing: vein 2+3Rs slightly sinuous; ramellus absent; vein 1M+Rs posteriorly faintly sinuous; vein 1cu-a posteriorly markedly curved, arising far from vein 1M+Rs base, angle with vein M+Cu about 90°; vein 2Cu 0.69 as long as vein 2cu-a; vein 4Rs 0.94 as long as vein 4M, slightly sinuous, almost straight; cell 1+2Rs 0.80 as high as pterostigma, rectangular; vein 2M distinctly shorter than vein 3M; vein 3M distinct, 1.50 as long as vein 2M. Hind wing: vein 1Cu 1.67 as long as vein cu-a; vein 2-1A reaching 0.86 of distance to posterior margin.   
 Legs. Tibia with sparse short bristles; hind coxa globose.   
 Metasoma. T1 0.55 as long as hind femur, with faint basolateral tooth; anteriorly smooth, posteriorly coriarious; spiracle at anterior 0.63, slightly prominent; postpetiole dorso-anteriorly convex; T2–8 minutely coriarious; almost glabrous; T2 0.90 as long as wide at apex; apex of T2 1.69 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 and yellow (232,212,089). Head: light yellow; clypeus apically, supraclypeal area ventrally, supra-antennal area medially, vertex and gena, except genal orbit, and occiput, black; mouthparts, mandible apex, scape, pedicel and flagellum, brown; flagellum entirely whitish at f5–12, partially at f4. Mesosoma: black, except for the following bright yellow marks: propleuron ventrally, collar laterally, pronotal swelling, large longitudinal mark at almost entire length of central lobe of mesoscutum, axillary carina, scutellum, postscutellum, upper division of metapleuron, 0.6 dorsal of lower division of metapleuron, posterior portion of propodeum except medio anteriorly, mesothoracic venter centrally, and three large marks at mesopleuron: subalar ridge, ventral half of mesopleuron, and 0.7 dorsal of hypoepimeron. Legs: mostly orange (206,097,026); all t5 black; fore and mid coxae ventrally fulvous, dorsally yellow; hind coxa yellow with two not connected fulvous marks: dorsal anchor-shaped spot at apical 0.6, ventral large spot reaching basal 0.7. Metasoma: black, fulvous, and yellow; T1 black with medial 0.6–0.8 fulvous, posterior 0.2 yellow; T2 fulvous with posterior 0.2 laterally dark yellow (194,129,057); T3–8 fulvous, blackish towards apex, with posterior 0.4 yellow; S1 black; S2–5 pale yellow, laterally black; S6–8 black, posterior 0.1 yellow.   
 Comments. The propodeal and metasomal color patterns, and the blunt apophysis are unique and characteristic for the species (Figs 20, 141, 199).   
 Male. Unknown.   
 Distribution. Known only from Suriname (Fig. 234).   
 Biology. Unknown.
