Description.

Head yellow with a five-pointed star-like mark centrally on vertex, more conspicuous in female (Figs 3 D View Figure 3 , 5 D View Figure 5 ). Forewing with a large white transparent patch against costal margin sub-basally (Fig. 3 A, B View Figure 3 ).

External features as in generic description.

Male genitalia. Pygofer side wide basally, apex narrow, with numerous macrosetae on posterior area (Fig. 6 A View Figure 6 ). Anal tube short (Fig. 6 A View Figure 6 ). Valve approximate trapezoid, nearly 2.5 × as broad as median length (Fig. 6 B View Figure 6 ). Subgenital plate subtriangular, without macrosetae along lateral margin, length of outer margin about 2.2 × width of base (Fig. 6 B View Figure 6 ). Aedeagus sinuate in lateral view, without basal apodeme, expanded laterally and lamellate in basal half, shaft tubular, gonopore apical (Fig. 6 C – E View Figure 6 ). Connective articulated with aedeagus, ‘ T’ shaped in ventral view with stem nearly two-thirds length of arms, arms upturned (Fig. 6 C – E View Figure 6 ). Style elongate, outer basal arm long and tapered to apex, inner basal arm very short; apical process strongly curved basally and tapered to acute apex; preapical lobe relatively long, lying parallel to apical process (Fig. 6 F View Figure 6 ). Dorsal connective present in phragma adjacent to base of aedeagal shaft (Fig. 6 D View Figure 6 ).

Female genitalia. Middle width of seventh sternite about 1.6 × middle length, posterior margin slightly sinuate, with a small groove in middle (Fig. 4 B View Figure 4 ). Pygofer with ventroposterior margin slightly incurved (Fig. 4 A View Figure 4 ). First valvulae of ovipositor with dorsal sculpture reticulate basally, with sculpturing grading to strigate and concatenate apically (Fig. 4 D, C View Figure 4 ). Second valvulae with toothed distal section longer and conspicuously broader than fused basal section, more or less parallel-sided, with teeth prominent and evenly spaced, gradually becoming smaller distally, apex of teeth rounded (Fig. 4 E, F View Figure 4 ).
