Figs 1–6 , 7–15

Description.

Body red (Figs 1–4 ). Anterior margin of crown arcuate, posterior margin concave, a large black spot in middle of anterior margin of crown. Eyes black, ocellus located on top of head in line with antennae, and crown suture conspicuous, not reaching anterior margin of crown. Pronotum red, anterior area with irregular spots, and angles on both sides of scutellum have black spots (Figs 1 , 4 ). Forewings reddish and hindwings translucent (Figs 5 , 6 ).

Male abdominal apodemes extend to middle of 5 th abdominal segment, and they are slender and parallel (Fig. 7 ). Lateral valves of male pygofer side broad at base, narrowed in terminal half, coarsely setae, without ventral appendage (Fig. 9 ). Anal process developed, extending toward tip, distinctly exceeding posterior margin of pygofer, subterminally with many grooves (Fig. 9 ). Subgenital plate gradually narrowed basally to tip, with 1 macrosetae and 17 marginal setae (Figs 9 , 10 ). Paramere curved, inflated at middle, pointed at tip and without teeth (Figs 12 , 15 ). Aedeagus curved in lateral view, with short whiskers at apex of shaft and with a pair of protuberances on each side of ventral margin of shaft, which are distinctly curved ventrally beyond apex of shaft, and in dorsal view with shaft protuberances forked (Figs 12 , 13 , 14 ). Connective not developed (Figs 12 , 13 ).
