Unknown.
Head. Scape less than two times longer than maximally wide. Apical lobe of scape absent, margin of scape and pedicel without dense cluster of setae. First flagellar segment equal to or shorter than second, surface regularly smooth or finely sculptured. Maxillary palpi six-segmented, labial palpi four-segmented, third labial palp segment as long as or longer than second. Malar suture absent. Frons without lateral protuberances. Occipital carina present, at least laterally. Vertex not striate, smooth.
Mesosoma. Propleuron only smoothly rounded. Pronotum dorsally without modifications (or convex lobe). Notauli complete or at least partly present (smooth or sculptured). Prescutellar depression (scutellar sulcus) long and narrow or of medium length. Prepectal carina present. Propodeal bridge between abdominal and coxal foramina present, narrow. Propodeum completely or partly (micro)sculptured. Propodeal carinated areas completely absent. Propodeum without median process.
Wings. Wings present. Radial (marginal) cell of fore wing distally closed. Second radiomedial vein (r-m) of fore wing present, with wide bulla. First radiomedial vein (2-SR) of fore wing present, leading the first and second submarginal cells of fore wing separated. Recurrent vein (m-cu) of fore wing postfurcal (arising distad 2RS, (RS+M)b absent), or interstitial or antefurcal (arising basad or directly in line with 2RS, (RS+M)b present then second submarginal cell petiolate horizontally). Nervellus (cu-a) of fore wing present, postfurcal or interstitial. Parallel vein (CU1a) relative to cubital vein (2-CU1) of fore wing not interstitial, arising behind middle of distal vein of brachial cell (short space between the curved part and the level of 2–1A vein), brachial (1st subdiscal) cell of fore wing distally closed. Fore wing of male without sclerotized enlargement, including veins 1-m and 1-SR + M. Hind wing with four to eight distal hamuli. Hind wing without transverse vein (r) of radial cell. Hind wing with the recurrent vein (m-cu), recurrent vein (m-cu) not curved towards apex of wing. Hind wing with the nervellus (cu-a) vein. Hind wing male without a stigma-like enlargement. Hind wing with a small or medium sized submedial (subbasal) cell, the first abscissa of M + CU 0.2–1.0 times as long as second abscissa (1-M). Medial (basal) cell of hind wing closed.
Legs. Fore tibial spines present, usually few and forming a single row. Subapical teeth on fore and middle femora ventrally absent. Hind coxa dorsally without teeth. Dorsal spines of hind tibia absent. Hind femur without teeth on ventral side. Basoventral tooth of hind coxa absent.
Metasoma. Dorsope of first metasomal tergite absent or indistinct. Acrosternite of first metasomal tergite very long, 0.6–0.85 as long as tergite and entirely fused with its ventral margin, petiole present and long. First and second tergites not fused. Laterotergites separated from each other for at least second and third tergites, separated only at second and third tergites. Second tergite without apical lenticulate area. Second tergite basal area enclosed by carinae or grooves present (sometimes shallow grooves), basal area of second tergite separate from second suture. Second metasomal suture largely or entirely absent. Third tergite medially without any distinct transverse narrow depression. Fifth or sixth metasomal tergites not enlarged, not covering succeeding tergites and entirely smooth. Fourth-sixth metasomal tergites of males smooth (or striate/coriaceous) basally, simple, submarginal lateral carinae absent. (modified from Belokobylskij [1])

This genus resembles Schlettereriella. It differs in having the first flagellar segment of antennae almost equal to or weakly shorter than second segment, the fore femur on inner side with numerous coarse regular oblique carinae, the hind coxa of female with distinct basoventral tooth but without tooth in male, the sternaulus absent, the acrosternum of first tergum long (about 0.8 times as long as tergum), the recurrent vein postfurcal or interstitial, the pronope and high pronotal carinae always present, the fore trochantellus dorsally with distinct transverse carina transformed to pointed flange on its inner part, the vertex and most of mesoscutum smooth, hypopygium with distinct insertion on posterior margin, and the second suture weakly curved and fine [1].
It differs from Australospathius and Oroceguera by having the second tergum with two more or less distinct furrows (without any furrow for these two genera) [1].
It differs from Leptospathius by the first flagellar segment of antennae almost equal to or weakly shorter than second segment, the fore femur on inner side with numerous coarse regular oblique carinae, the hind coxa of female with distinct basoventral tooth (male without tooth), the sternaulus absent, the acrosternum of first tergum long (about 0.8 times as long as tergum), the recurrent vein postfurcal or interstitial and the pronope and high pronotal carinae always present [1].
