D e s c r i p t i o n: ♀. Body length 5 mm. Flagellum slender and filiform, with 26 flagellomeres, 1 st flagellomere 4.0× and 2 nd flagellomere 3.2× longer than wide, combined length 0.69× eye length, preapical flagellomer slightly longer than wide. Temple strongly narrowed behind eye. Distance between lateral ocellus and compound eye 0.9× ocellar diameter. Frons with scattered punctures and shining; face and clypeus densely punctured, smooth and shining between punctures. Clypeus 3× wider than long, flat, with straight apical margin. Malar space 0.8× as long as width of mandibular base. Gena narrow, c. 0.5× as wide as eye in lateral view. Genal carina reaching hypostomal carina far from mandibular base. Mandible slender, with almost parallel sides; upper mandibular tooth much longer than lower tooth.

Side of pronotum with superficial punctures, shining. Epomia very long and almost reaching hind margin of pronotum ( fig. 12 View Fig ). Notaulus indistinctly impressed. Mesoscutum with punctures, granulate and dull. Mesopleuron densely punctate, partly with longitudinal striation in ventral part; speculum large, almost smooth and strongly shining. Sternaulus impressed in frontal third of mesopleuron. Metapleuron punctate; juxtacoxal carina present. Scutellum slightly convex, about as long as wide, with strong lateral carina almost to apex, with very scattered punctures, strongly shining. Propodeum with clearly differentiated basal horizontal and apical vertical parts, similar to Microlongichneumon, but anterior transverse carina (costula) present in frontal half of area superomedia. Propodeal spiracle c. 2× longer than wide. Mid and hind coxae densely punctate; hind coxa without scopa. Hind femur 4.4× longer than wide, densely punctate. Claws simple. Areolet of fore wing strongly narrowed frontally, frontal distance between vein 2rs-m and 3rs-m 1.5× their width; vein 2m-cu reaching middle of areolet. Vein 1cu-a interstitial.

Metasoma oxypygous. Postpetiolus slightly widened to apex; median field not clearly separated, almost completely smooth and shining. 2 nd tergite 0.9× as long as wide. Gastrocoelus not distinctly impressed. Thyridium small, 0.5× as wide as interval between thyridia. 2 nd and 3 rd tergites densely punctate and granulate, dull; 3 rd tergite ± shining apically. 4 th and 5 th tergites with very superficial punctures, smooth and shining. Ovipositor sheath slightly reaching behind metasomal apex.

Color: yellowish-brown. Stripes or rings on flagellomeres 8-13, stripes on frontal orbit, on vertex and on upper outer orbit ivory. Petiolus yellowish brown. Postpetiolus and following tergites dark brown, 6 th and 7 th tergites dorsally with large ivory marks. Legs reddish brown, all femora yellowish red in basal 0.1. Wings hyaline; pterostigma yellowish.
