<paragraph pageId="0" pageNumber="55">Head and thorax. Head (Figs 3, 20) including eyes distinctly narrower than pronotum (1:1.63). Vertex (Figs 3, 20) at base wider than length in middle line (1:0.62), apex narrower than base (1:1.45), straightly projecting before eyes, median carina absent, lateral margin distinctly carinate, posterior margin slightly concave. Frons (Fig. 21) moderately narrow, near frontoclypeal suture widest, disc concave, lateral margins broadly concave inward, distinctly carinate, median carina absent. Postclypeus (Fig. 21) with median and lateral carinae, anteclypeus with weak median carina, lateral carinae absent. Apical segment of rostrum longer than wide. Antennae (Figs 20, 22) short, second antennomere oval, flagellum originated from apical point. Subantennal processes (Figs 21, 22) small. Eyes (Figs 21, 22) semicircular; ocelli present, adjacent to eyes. Median length of pronotum short, anterior margin between eyes convex, posterior margin deeply concave, median carina distinct. Mesonotum (Fig. 20) as long as broad, slightly convex, in lateral view raised above vertex, with median carina distinct and lateral carina weak, posterior end triangularly depressed. Forewing (Fig. 23) narrow, 3.3 times as long as the widest point, clavus closed, claval veins with a prominent ridge of tubercles, base of costal margin curved inward, costal margin also granulated.

Anal tube (Fig. 25) in lateral view, obliquely, slender at basal half, apical margin rounded, anal styles sets at basal one-fifth; in dorsal view (Fig. 26), length in middle line approximately three times as long as wide at middle, asymmetrical, apex rounded. Pygofer (Fig. 25) in lateral view distinctly narrowed medially, processes (Fig. 27) of pygofer asymmetrical, left dorsocaudal process slightly longer than right one. Gonostyli (Fig. 25) bilaterally asymmetrical, right gonostylus larger than left one, large, elongate and slightly reaching less than apex of anal tube in lateral view, inner side with saccate process at basal two-thirds near ventral margin, left gonostylus with a small process rising from apical one-fifth of dorsal margin. Phallus asymmetrical, periandrium curved, with a hooked process near base ventrally directed caudally, in left lateral view (Fig. 28), with a slender process near middle, directed dorsocaudally, and two stout processes at apex, in right lateral view (Fig. 29), with a plate near apex, and a long process at apical two-thirds, slightly curved, directed dorsally, apical margin serrate. Aedeagus with five spinous processes at apex, the largest process produced reaching to base of periandrium, acute at apex.</paragraph>
