Wings almost covering abdomen ( Fig. 36D ). Tegmen: Radius with two branches, both forked near tip; media anterior free from base but temporarily touching CuA, forked behind basal third into two veins: MA and MP; cubitus anterior and cubitus posterior both single branched, free throughout; with 3–4 anal veins.

Legs: Hind tibia with a pair of very long and curved spines in subbasal area of dorsal margins ( Fig. 36D arrow), afterwards with only one or two normal spines; ventral margins with one subapical spine; with three apical spurs at each side.

Subgenital plate prolonged but fissured in midline with fissure widening from base towards apex, widest at about beginning of apical quarter ( Fig. 36F ). Base of ovipositor in set specimen ventrally free, not covered from subgenital plate. Ovipositor long, moderately upcurved throughout; tip subacute.
