( Figs 40 −64, 68, 69) Diagnosis. Male sternite VIII (Fig. 44) as long as wide. Pygofer (Fig. 46) with ventral margin emarginated. Connective (Fig. 48) with stem spatulate. Aedeagus (Figs 50−52) shaft with lateral processes arising at apical third, bifur- cated: one ramus directed dorsally extending a little farther than shaft apex and another directed ventrally extending as far as mid-length of shaft. Measurements (mm). Holotype male: total length 6.8. Paratypes : males 6.8−7.5, females 8.4−8.6. Coloration. Crown ( Figs 40 , 53 ) with two small black spots anterolaterally to ocelli. Forewing of female (Fig. 56) with costal margin yellow and larger black maculae on cross veins of discal cell. Other characteristics as in generic description. Description. External morphological characters as in generic description. Male terminalia. Sternite VIII (Fig. 44) in ventral view, as long as wide; posterolateral angles broadly rounded; posterior margin emarginated. Valve (Fig. 45) in ventral view, approximately 1.3 times wider than long; lateral margins convex; ventral margin produced at middle portion. Pygofer (Fig. 46) in lateral view, with ventral margin emarginated. Subgenital plate (Fig. 46) in lateral view, extending posteriorly farther than pygofer apex; in ventral view (Fig. 47), approximately 6.1 times longer than wide. Connective (Fig. 48) in dorsal view, with stem longer than arms; stem spatulate. Style (Fig. 48) in dorsal view, with outer lobe acute; in lateral view (Fig. 49), with blade gradually expanded towards apex. Aedeagus (Figs 50−52) shaft with lateral processes arising at apical third, bifurcated: one ramus directed dorsally extending a little farther than shaft apex and another directed ventrally extending as far as mid-length of shaft, apices of processes acute. Female terminalia. Sternite VII (Fig. 57) in ventral view, subrectangular, approximately 1.9 times wider than long; posterolateral angles rounded; posterior margin roundly excavated at mid-portion. Internal sternite VIII membranous. Female pygofer (Fig. 58) in lateral view, about 1.7 times longer than maximum height; macrosetae distributed near apex and median portion; apex rounded. First valvifer (Fig. 59) in lateral view, approximately 1.3 times higher than long; anterodorsal angle rounded; anterior margin slightly excavated; dorsal and posterior margins almost straight; posteroventral angle broadly rounded. First valvula (Fig. 59) in lateral view, slightly curved dorsally; about 5.5 times longer than high; slightly higher near mid-length; apex (Fig. 60) with dorsal sculptured area strigate; apex acute. Second valvula (Fig. 61) in lateral view, approximately five times longer than high; apical third (Fig. 62) with irregularly shaped teeth, basal tooth bigger and truncate; apex tapered and subacute. Third valvula (Fig. 63) in lateral view, about 3.2 times longer than high; dorsoapical and ventroapical margins convergent; ventral margin with dentiform cuticular projections; apex (Fig. 64) subacute.
