Head and thorax. Ratio width of vertex from base to length in midline 2.1. Ratio length of frons in midline to maximum width 1.6, ratio maximum width to width at base 1.7. Ratio length of postclypeus in midline to length of frons 0.7. Ratio of apical to subapical segment of rostrum 1.2. Ratio length of pronotum in midline to length of vertex 1.2. Mesonotum in midline 3.7 times longer than pronotum, 2.0 times longer than pronotum and vertex combined. Forewing with ratio of length to maximum width 2.8. Hindwing with ratio of length to maximum width 1.7.

Male genitalia. Anal segment in dorsal view subquadrate (Fig. 92), as long as wide (maximum width), apical margin slightly round. Pygofer in lateral view (Fig. 93) with dorsal margin distinctly longer than ventral margin, with the narrowest part in the middle, anterior margin concave; in ventral view (Fig. 94), medioventral process of pygofer entire and rectangular, with base two-thirds convex in the midline. Genital style distinctly longer than wide, with 3 processes arising from middle of dorsal margin; inner surfaces near dorsal margin at basal third with 1 relatively long and bent process (Fig. 95). Aedeagus with phallobase sheath-shaped and symmetrical, dorsal lobe shorter than the lateral and ventral lobe (Figs 96, 98), with apical margin angularly convex in the middle (Fig. 96), each lateral margin dorsad rising from 1 valviform process (Figs 96, 98); ventral lobe (Fig. 97) with apical margin deeply cleft in the middle, ventral surface ventrad rising from 3 processes, directed basad, the middle one long, spine-like, 2 others symmetrical beside the midline, each with many sharp teeth apically (Figs 97–98)
