THE DECUI GROUP

Diagnosis: Forewing not extensively covered with small spots ( Fig. 36G–I ), marginal clouds apparent and dark; Rs fork obtuse; 3rd section of CuA arched. Male terminalia. Eighth venter ( Fig. 44C ) with large transverse sclerite medially fused with hypandrium. Epiproct ( Fig. 44A.B ) chair-shaped, postero-dorsal margin with projection at middle, epiproct lobe protruded over clunium, variable in shape ( Figs 43B , 44B , 46C ). Hypandrium ( Fig. 44C ) symmetrical, left and right processes short. Median tongue very short and rounded. Phallosome ( Figs 43D , 44D, E , 46E, F ): pseudoparameres usually needle-like, projected posteriorly; aedeagus usually broadly sclerotized and strongly projected posteriorly. Female genitalia. Egg guide of subgenital plate ( Fig. 45A ) broadened at distal end, dorsal surface with median sclerite. Ventral valve of gonapophyses ( Fig. 45B ) long; posterior lobe of external valve not strongly projected. Internal plate ( Fig. 45C ) symmetrical; spermathecal opening surrounded by triangular pigmentation; anterior half with pair of pigmented arms.
