Mesosoma short and high, its length 1.7–1.8 times maximum height. Mesoscutum (dorsal view) as wide as median length. Median lobe of mesoscutum protruding anteriorly, almost straight or slightly convex on anterior margin. Notauli entirely, distinctly and densely crenulate, with slight reticulation at least partly. Prescutellar depression almost smooth, with five-seven high carinae, 0.35–0.45 times as long as scutellum. Metanotum with fine and short median and distinct two curved and divergent posteriorly lateral carinae, medioposterior convex area wide and distinct. Sternaulus deep, entirely finely crenulate on very narrow median line, running along anterior 0.7 of lower part of mesopleuron.
Wings. Fore wing 3.6–3.8 times longer than maximum width. Metacarp (R1) 1.30–1.45 times longer than pterostigma. Radial (marginal) cell narrow, 5.3–5.5 times longer than maximum width. Second radial abscissa (3RSa) 0.8–1.0 times as long as first abscissa (r), 0.10–0.15 times as long as the straight third abscissa (3RSb), 0.70–0.85 times as long as first radiomedial vein (2RS). Second radiomedial (r-m) vein distinctly inclivous. Second radiomedial (second submarginal) cell trapezoid, 1.5–2.0 times longer than its maximum width, 0.65–0.70 times as long as the wide brachial (first subdiscal) cell. First medial abscissa ((RS+M)a) slightly sinuate. Recurrent vein (mcu) 6.5–12.0 times longer than second abscissa of medial vein ((RS+M)b), 1.1–1.2 times longer than first radiomedial vein (2RS). Mediocubital vein (M+CU) slightly sinuate. Nervulus (1cu-a) postfurcal, distance between basal (M) vein and nervulus (1cu-a) about half nervulus (1cu-a) length.

First tergite 0.6–0.7 times as long as its apical width, 0.8–1.0 times as long as propodeum; maximum width of tergite 1.8–1.9 times its minimum width. Suture between first and second tergites rather deep. Median length of second tergite 0.75–0.80 times its basal width, 1.7–1.8 times length of third tergite. Ovipositor sheath 1.2–1.5 times longer than metasoma, 2.5–2.8 times longer than mesosoma, 1.0–1.2 times as long as fore wing.
Sculpture and pubescence. Vertex mainly smooth, finely striate laterally of posterior ocelli; frons entirely rugose or rugulose, with curved striae before anterior ocellus. Face almost entirely coarsely rugose-reticulate, almost smooth on narrow vertical median stripe; temple smooth, sometimes finely rugulose posteriorly.
Mesoscutum almost smooth, partly finely coriaceous, with two-four convergent or subparallel carinae and wide rugosity in medioposterior 0.4 of mesoscutum. Scutellum and mesopleuron smooth, posterior mesopleural suture entirely coarsely crenulate. Metapleuron densely and coarsely reticulate-areolate. Propodeum with areas delineated by distinct carinae; basolateral areas rugose at least in posterior 0.5-0.7 and smooth or almost smooth in anterior 0.3–0.5, rarely almost entirely sculptured; areola short and wide, rugose-striate; basomedian carina usually almost as long as anterior fork of areola. Hind coxa dorsally transverse striate with rugulosity basally, finely punctaterugulose laterally becoming smooth ventrally or sometimes entirely smooth laterally. Femur entirely smooth. First tergite coarsely rugose-reticulate, almost smooth or slightly sculptured in basomedian part; second tergite coarsely rugose-reticulate, coarsely crenulate on transverse furrows, smooth in basal and apical areas. Third to fifth tergites medially punctate-reticulate or only punctate in basal 0.2–0.3 and laterally distinctly rugose-striate on almost all areas, remaining parts of tergites smooth. Sixth tergite finely punctate-coriaceous in basal 0.3–0.5 and smooth on remaining apical parts. Vertex with dense and long semi-erect pale setae, glabrous submedially on narrow area. Mesoscutum almost entirely with long, dense and numerous white setae, with considerably narrow glabrous areas on all lobes. Mesopleuron mainly glabrous. Hind tibia dorsally with numerous, dense and long semi-erect pale setae, length of setae 0.5–0.9 times maximum median width of hind tibia.
Colour. Head black, partly dark reddish brown. Mesosoma dark reddish brown in anterior 0.3–0.5 to reddish brown in posterior 0.5–0.7. Metasoma entirely reddish brown to light reddish brown. Antennae entirely black. Palpi dark brown or dark reddish brown basally becoming reddish brown or light reddish brown apically. Legs entirely black, with reddish tint. Ovipositor sheath black, occasionally dark brown medially. Fore and hind wings distinctly darkened, without subhyaline lines or stripes. Pterostigma entirely black.
Male. Unknown.
Etymology. This species named in honour of Victor Toledo-Hernandez (Universidad Autónoma de Morelos), who collected the most of the type material of this species.
Distribution. State of Morelos, Central Mexico.
