Diagnosis

Reference	Diagnosis
S. Y. Storozhenko 1992	Head large, wider than pronotum; compound eyes and ocelli well developed; mandibles large and pointed at vertices. Pronotum transverse, with full ring of wide rims; its width 1.3-1.9 times exceeding its length. Femora and tibiae lacking spines and spurs. Ovipositor slightly curved upward. Eggs elongated-oval; chorion strongly sclerotized, with sharp longitudinal costulae. Forewing lacking bristles and with almost straight frontal margin; Sc abutting on C in distal third of wing; R without branches; RS diverging from R in anterior third of wing and having five to eight branches. Base of M entirely merged with CuA; MA and MP diverging from CuA separately from each other, simple or branching CuAl simple or with two or three branches; Cu~ and CuP simple; area between CuA and CuP with nonbranching regularly S-curved crossveins. Ai having three and A2 two to four branches. Hindwing like forewing, but always showing distinct anastomosis between RS and MA; CuAl simple.
