Unknown.
Head. Head subcubical, 1.3 times wider than medially long. Scapus with distinct semicircular apical lobe, rather narrow and long, 2.5 times longer than maximum width. Palpi relatively long; maxillary palps 6-segmented, labial palps 4-segmented. Third segment of labial palps shortened, subtriangular, 0.55-0.6 times as long as 2nd and 4th segments separately. Hypoclypeal depression small and round. Clypeal suture wide and complete. Subocular (malar) suture very shallow. Face with two distinct submedian, oval depressions above clypeal suture. Eyes glabrous. Frons not concave and without a mediolongitudinal keel. Ocellar triangle with base 1.2 times longer than sides. Postgenal bridge very narrow.
Mesosoma. Neck of promesosoma rather long, more or less flat dorsally, with two distinct elongate, obtuse, wide lateral protuberances. Pronotal keel high, concave medially, situated near anterior margin of pronotum. Propleura without protuberances. Propleural lower lobe distinct and wide. Mesonotum rather highly and roundly raised above promesosoma. Medial lobe of mesonotum without antero-lateral angulations (corners). Notauli smooth, deep along anterior half, shallow or almost absent posteriorly. Prescutellar depression rather short and sculptured. Scuto-scutellar suture distinct. Scutellum weakly convex, without lateral carinae, 1.3 times longer than maximum width. Postscutellum (median area of metanotum) with short, flat medial tooth. Subalar depression deep, narrow and placed rather low. Mesopleural pit shallow. Sternauli deep, long, straight, and crenulate. Prepectal carina distinct and complete, not higher than sternauli. Prepectus with distinct and oblique lateral furrows. Metapleural flange rather long, wide and round apically. Metapleural suture present. Propodeum without areas; lateral, tubercles and propodeal bridge absent. Propodeal spiracles small.
Wings. Pterostigma of fore wing wide; Vein r arising almost from middle of pterostigma. Marginal cell slightly shortened. Veins 2RS and r-m present. Vein m-cu antefurcal. Vein m-cu interstitial. Discoidal cell short, petiolate. Vein 2CUb arising from posterior fifth of apical side of 1st subdiscal cell. First subdiscal cell closed. Veins la and 2a absent. Hind wing with four hamuli on vein R1. Vein cu-a present. Subbasal cell large. Vein M + CU nearly twice length of 1M. Vein m-cu present, antefurcal, almost perpendicular to medial vein. Basal cell wide, 0.55 times as long as hind wing. Vein RS arising from vein 1M near vein R1. Marginal cell weakly narrowed towards apex, without additional transverse vein. Vein C + SC + R 1.5 times length of SC + R.
Legs. Fore and middle tibiae with one longitudinal row of widely-spaced, large spines. Hind tibia with two small spines apico-laterally, and with area of dense white setae near apex medially. Hind coxa small, without basoventral tooth. Femora simple, without dorsal protuberances. Hind femur 3.5 times longer than wide. Hind tibial spurs rather short, weakly thickened, sparsely setose, inner spur approximately 0.33 times as long as hind basitarsus. Hind basitarsus 0.7 times length of segments 2-5 combined.
Metasoma. First tergite not petiolate, wide, with small round basolateral lobes. Dorsope large. Spiracular tubercles indistinct, spiracles located on basal third of tergite. Acrosternite approximately 0.25 times as long as 1st tergite, its apical margin distinctly before spiracles. Second tergite with small, semi-oval mediobasal area. Second suture distinct, weakly curved laterally. Second and third tergites with separate laterotergites. Hypopygium small, with two pointed and separate processes medioposteriorly. Ovipositor longer than metasoma; apex of dorsal valve with 2 small nodes [1].

This new genus belongs to the Binariini (sensu Belokobylskij, 1992) being most closely related to the Neotropical genus Liobracon Szepligeti. The Binariini are defined by the following synapomorphies: occipital carina absent, neck of pronotum with one or two obtuse or pointed tubercles or spines, hind coxa without ventral tubercle, second metasomal tergite with furrows defining an area and usually with the third segment of the labial palp distinctly shortened. All of these are also displayed by the new genus. The new genus differs from Liobracon in the scapus not being depressed and lacking the dense apical row of setae, though the scapus does have a distinct apical lobe as in Liobracon. It also differs in that the marginal cell of the hind wing lacks an additional transverse vein, and in that the dorsal part of the pronotum is flat and has low lateral tubercles. The new genus also appears to be related to the Australian binariine genus Acanthodoryctes Turner from which it differs in having the third segment of labial palp short, frons rather flat, scapus with distinct apical lobe, marginal cell of fore wing not shortened, hind wing with vein m-cu, pronotum without a pair of spine-like protuberances, and 1st metasomal tergite without especially modified setosity (from [1]).
