Head. Head weakly transverse, its width 1.53 median length. Ocelli almost an equilateral triangle. Antennal socket situated at upper level of eyes, its maximum diameter 0.8± 0.93 distance between sockets, almost twice distance from socket to eye. Eyes glabrous. Occipital carina distinct, shortly interrupted dorsally, ventrally absent at long distance. Malar suture very shallow or absent. Hypoclypeal depression round. Postgenal bridge rather wide. Palpi short; maxillary palpi five-segmented, labial palpi three-segmented. Scapus rather long, without apical lobe; length of scapus 1.7± 1.93 its maximum width. Three or four basal segments of flagellum without placoid sensilla.
Mesosoma. Neck of promesosoma rather short. Pronotal keel present, but fine, situated in anterior third of pronotum. Propleural lobe present and narrow. Mesonotum highly and convexly raised above pronotum. Notauli smooth, deep in anterior half, more or less shallow in posterior half. Scuto-scutellar suture present. Postscutellum without median tooth. Mesopleural pit narrow, long, oblique, running along most parts of mesopleura. Sternauli absent or almost absent. Prepectal carina present ventrally only. Metapleural flange absent. Propodeum without marginate areas, lateral tubercles very small or indistinct, propodeal bridge absent. Propodeal spiracles small and round, situated in basal one-quarter. Metapleural suture indistinct.
Wings. Pterostigma of fore wing narrow and long; radial vein arising before middle of pterostigma. Both radiomedial veins present. Recurrent vein postfurcal. Nervulus present. Discoidal cell very shortly petiolate. Parallel vein almost interstitial. Brachial cell closed. Transverse anal veins absent. Hind wing with four hamuli. Nervellus present. Submedial cell small. First abscissa of mediocubital vein 0.63 as long as second abscissa. Recurrent vein present. Medial cell narrow, 0.43 as long as hind wing. Radial vein arising from costal vein. Radial cell narrowed toward apex, without additional transverse vein. Wings of male narrow and distinctly shortened, fore wing with sclerotized apical third.
Legs. All femora ventrally with more or less distinct subapical teeth, but in hind femur this tooth small; in male all these teeth small. Fore and middle tibiae with sparse small spines almost in one row. Hind tibia with four slender spines in outer distal margin and with sparse hairs in inner distal edge. All basitarsi subcylindrical and straight. Hind coxa small, without basoventral tooth. All femora without dorsal protuberances. Hind tibial spurs rather short, slender, glabrous, but with single long median seta; inner spur about 0.33 as long as hind basitarsus. Basitarsus of hind tarsus 0.8± 0.93 as long as second to fifth segments combined.
Metasoma. First metasomal tergite petiolate, rather wide. Acrosternite 0.5± 0.63 as long as first tergite, its apical margin situated significantly behind spiracles. Dorsope of first tergite and basolateral lobes absent. Second suture indistinct. Third to sixth tergites entirely shortly setose. Second tergite without areas or furrows. Second and succeeding tergites without separate laterotergites. Ovipositor shorter than metasoma. Apical part of ovipositor with two small dorsal nodes and serrate ventrally [1].

It is similar to the genus Spathius but is distinguished by the palpi with fewer segments, basal segments of flagellum without placoid sensilla, metapleural flange absent, all femora with a more or less distinct ventroapical tooth, third to sixth metasomal tergites shortly setose entirely and body almost entirely smooth.
It is also similar to Embobracon but is distinguished by the basal segments of the flagellum without placoid sensilla, metapleural flange absent, all femora with more or less distinct ventroapical tooth, postfurcal position of recurrent vein, closed radial cell of fore wing, closed medial cell of hind wing, distinct notauli, and hypopygium of female not retracted under metasoma [1].

Related to the tribe Spathiini by the presence of synapomorphic characters: long acrosternite of first metasomal tergite (which is longer than half of tergite) and the venation of the fore wing (Belokobylskij, 2002).
