Characteristics of the genus. Head weakly transverse (dorsal view). Ocelli arranged in triangle with base large than its sides. Eyes glabrous. Malar suture absent. Occipital carina present, not joined with hypostomal carina, being obliterated below. Postgenal bridge narrow. Maxillary palpus 5-segmented, labial palpus 3-segmented. Scape wide and short, without apical lobe or flange. First flagellar segment distinctly shorter than second segment. Mesonotum (lateral view) usually highly and almost perpendicularly elevated above pronotum. Median lobe of mesonotum (dorsal view) with obtuse or pointed anterolateral angles. Notauli entirely rather deep. Sternaulus more or less shallow, rather short and straight. Prepectal carina distinct and complete. Propodeum often with areola delineated by carinae; lateral tubercles and propodeal bridge absent. Radial (marginal) cell of fore wing usually not or weakly shortened. Second radiomedial vein ( r-m ) absent. Discoidal (discal) cell petiolate anteriorly. Recurrent vein ( m-cu ) distinctly or strongly antefurcal. Nervulus ( cu-a ) always absent. Fused submedial (subbasal) and brachial (subdiscal) cells closed apically on or before recurrent vein ( m-cu ). Parallel vein ( CU1a ) interstitial. In hind wing, nervellus ( cu-a ) and submedial (subbasal) cell absent. Recurrent vein ( m-cu ) absent. Medial (basal) cell narrow, always closed antero-distally. Fore tibia with small spines arranged almost in single line. Hind coxa with rather distinct basoventral corner and rounded tubercle. All femora without dorsal protuberances. Hind femur of male not or only weakly wider than female femur. Hind basitarsus 0.7–1.0 times as long as second–fifth segments combined. First metasomal tergite not petiolate, rather wide, with distinct dorsope. Acrosternite of first segment about 0.2 times as long as first tergite. Second suture shallow and straight or absent. Second tergite without furrows or delineated area, often smooth, but rarely entirely striate. Ovipositor usually shorter than metasoma; its apical part with two small dorsal nodes and serrate ventrally.
