This genus can be distinguished from other genera by the following combination of character states: clypeus without a weak convexity at centre, its apical margin thin and narrowly reflexed; lower tooth of mandible not longer than upper tooth; inner margin of eye not notched opposite antennal socket; flagellum covered with short setae and with an erect, short seta on apex of ventral surface ( Fig. 16 ); some apical flagellomeres as long as wide or wider than long; propleuron without a forward projecting flange; mesopleuron largely mat ( Fig. 26 ); posterior transverse carina of mesosternum complete ( Fig. 28 ); propodeum nor quite elongate and very short ( Figs 23, 27, 29 ); propodeal spiracle circular to elliptic; areolet usually present, receiving second recurrent vein distad of the middle; nervulus opposite basal vein, or distad of it by less than 0.3 its length; nervellus vertical or subvertical, not intercepted; discoidella not pigmented or absent; hind first tarsomere with a continuous, straight, median ventral row of very closely spaced small hairs ( Figs 18–20 ); tarsal claws small to moderate length and pectinate ( Figs 18, 21 ); glymma small, obsolescent or sometimes absent; ovipositor 1.0–2.2 × as long as hind tibia; apex of dorsal valve of ovipositor without a distinct convexity ( Fig. 22 ); body usually with large yellow areas ( Figs 23–29 ).

Two families, Crambidae and Cossidae (Lepidoptera) ( Gupta, 1973 ; Haeselbarth, 1983 ), have been recorded as the host while no record is known in Japan . Remarks .
