Clypeus basally evenly convex, apically gradually flattened, centrally concave; CHW 2.55; CWW 2.11; apical area medially concave, laterally with distinct triangular lobes, its margin very sharp, raised. Antenna with 24 flagellomeres; flagellum uniform; apex of apical flagellomere much narrower than base, distinctly tapered.

Mesoscutum moderately and uniformly convex, ovoid, 1.25 × as long as wide, densely covered with short hairs, shiny, densely punctate; notaulus reaching about 0.7 of mesoscutum length, moderately impressed, surface over notaulus with weak and short transverse wrinkles; scuto-scutellar groove moderately deep, with vestigial longitudinal wrinkles. Subalar ridge weakly projected; epicnemial carina reaching about 0.7 of distance to subalar ridge, irregular; sternaulus complete but weak, strongly sinuous, smooth; scrobe very shallow; mesopleural suture with vestigial longitudinal wrinkles. Mesosternum medially with short transverse wrinkles; median portion of posterior transverse carina of the mesothoracic venter short, straight. Transverse sulcus at base of propodeum very wide, about 0.78 × as long as anterior area of propodeum, posteriorly with longitudinal wrinkles; metapleuron with very fine and moderately dense punctures, with vestigial wrinkles, moderately pilose; juxtacoxal carina represented by very short ridges. Fore tibia distinctly swollen. Mesal lobe of t4 with a distinct cluster of stout bristles. Hind coxa with moderately strong punctures separated by about their own diameter.

PROPODEUM: 1.15 × as long as wide, shiny, sparsely pilose; anterior area densely punctate; spiracle elliptic, SWL 3.00; anterior transverse carina medially slightly arched forwards. Propodeal wrinkles anteriorly faint, posteriorly moderately strong, closely spaced, mostly complete, mostly slightly curved or somewhat sinuous; posterior transverse carina entirely absent.

WINGS: Fore wing vein 1-Rs+M distinctly sinuous, with bulla placed on basal 0.25; crossvein 1m-cu more or less uniformly curved, limit between 1m-cu and 1-Rs+M more or less traceable; vein 1M+Rs anteriorly straight, posteriorly curved; fore wing crossvein 1 cu-a basad of 1M+Rs by 0.4 of its own length; vein 2Cua 0.46 × as long as crossvein 2cu-a; bulla of crossvein 2m-cu placed mostly on posterior half; cell 1+2Rs small, APH 0.58, pentagonal, distinctly wider than high, AWH 1.31; crossvein 3r-m fully spectral, 2r-m and 3r-m subparallel, 3r-m distinctly shorter; vein 3-M about as long as 2-M; 4-Rs distinctly sinuous; 4-M tubular, slightly curved backwards. Hind wing vein 1-M forming straight angle with vein Cua; vein 2-Rs tubular, apically spectral, reaching wing margin; HW1C 1.17; vein Cub distinctly convex on posterior half, forming distinctly obtuse angle with vein Cua (basally curved); vein 2-1A reaching 0.94 of distance to posterior wing margin.

METASOMA: First tergite moderately long, about 0.37 × as long as T2–8, somewhat depressed, ventrolaterally rounded, dorsally glabrate, laterally sparsely pilose; T1LW 2.54; T1WW 2.23; spiracle on 0.52 of its length, distinctly prominent; median depression elongate, very shallow; lateral and median posterior depressions absent; ventrolateral carina absent, but traceable as limit between lateral and ventral portions. T2LW 1.18; T2WW 1.57; thyridium longer than wide, with small circular depression just behind it; T2–8 minutely coriarious, moderately and uniformly pilose. OST 1.14; ovipositor moderately stout, straight, basally cylindric, apically slightly depressed; dorsal valve with five moderately strong ridges; ventral valve apex with 9 teeth, apical teeth progressively more closely spaced; surface anterior to first tooth rugulose.

Color. Head and mesosoma black and pale yellow, metasoma dark brown and pale yellow. Head: black; clypeus, mouthparts, supra-clypeal area, scape and pedicel ventrally and complete orbital band, pale yellow (224,118,117) scape and pedicel dorsally and flagellum, brown; f7–12 entirely white, f13 almost entirely white, f6 and f14 partially white. Mesosoma: pronotum black except collar and dorsal margin connected, pale yellow; mesoscutum black except pale yellow subcircular spot; remainder of mesosoma pale yellow except for the following black marks: scuto-scutellar groove, both axillary through, scutellum posteriorly, axillar carinae, postscutellum, ventral 0.6 of epicnemium, scrobe and part of hypoepimeron, posterior apex of sternaulus, mesopleural suture, transverse sulcus, anterior area of propodeum except lateral portions, lateral border of propodeum and oval posterior spot; fore and mid legs pale yellow except apical brown spot at mid coxa, brownish stripe at fore and mid femora, fore t5 and mid tarsus dark brown; hind coxa pale yellow with three longitudinal brown stripes, anterior one on apical 0.6, posterior one on basal 0.6 and median one at full length of coxa, basally wider; hind trochanters mostly brownish, ventrally yellow; hind femur pale yellow with dorsal brownish stripe on basal 0.8; basal 0.3 of hind tibia pale yellow, turning to dark brown on apical 0.7. Metasoma: dark brown (058,051,045); T1 pale yellow, median 0.25 dark brown; T2–8 with posterior pale yellow stripes; S1-6 pale yellow, S2-4 with lateral brownish marks.

Male. Not examined. According to Kasparyan & Ruíz (2008), similar to female, except for the following: fore wing 5–8 mm long; mandible pale yellow (except apex); antenna with 24–26 flagellomeres; black marks on pronotum connected; epicnemium and metanotum partially to completely black; fore coxa entirely whitish; basal 0.7 of hind tibia whitish; T2 with small anterior whitish spot.

Variation. Fore wing 7.35–9.8 mm. Antenna sometimes with 23 flagellomeres; mesopleural suture sometimes pale yellow; anterior and posterior stripes at hind coxa sometimes distinguishable only as small brownish marks; hind femur dorsally mid brown to blackish; mid tarsi sometimes pale yellow, only slightly darker apically; black mark at mid coxa sometimes fading until its base; lateral portion of T1 sometimes black until the base. Yellowish spots at anterior area of propodeum almost indistinct at the smaller males.

Comments. Readily recognized by the following combination of characters: anterior area of propodeum with lateral yellowish marks over propodeal spiracle and surrounding area; arc-shaped mark at posterior area almost reaching borders of propodeum and anterior transverse carina; mandible entirely black; mesopleuron almost entirely yellow, central mark connected to yellow subalar ridge; and ovipositor dorsal valve with five moderately strong ridges.
