Diagnosis

♂: length of body 5.0–5.6mm, length of tegmen 3.8–4.1 mm; ♀: length of body 6.1–6.2 mm, length of tegmen 4.3–4.5 mm. Body very light brown, with darker areas on coxae, base and apex of fore and mid femora, ventral surface of hind femora, postclypeus and sometimes clypeus medially, base and apex of antennal segment 2, vertex adjacent to and on submedian carinae, veins of tegmen except for short lengths, ventral surface of pygofer and posterior area of ventral abdominal surface. Frons with submedian carinae and area between them red. In ♀♀ dark areas much more extensive, with lateral areas of frons often dark. Vertex in midline 1.25–1.5 x basal width, widest just before rounded apex; sides straight or nearly so, converging towards base; posterior margin concave or nearly straight; submedian carinae meeting before apex, often indistinct at apex; basal compartment about as wide as or slightly wider than long. Frons in midline 2.5–2.8 x greatest width; submedian carinae more or less straight, meeting about one-quarter to one-fifth from apex. Segment 2 of antennae 1.2–1.5 x length of segment 1. Pronotum with median carina subobsolete. Mesonotum with outer pair of carinae reaching posterior margin, weak median carina. Hind tibiae with 2 lateral spines in addition to basal and apical ones. Tegmen short, reaching anal segment, claval suture absent; Cu simple or forked very close to apex; M forked, 1 row of cross veins; apical veins simple. Anal segment of ♂ in lateral view with ventrolateral portion barely produced, posteriorly with more or less rounded apex. Pygofer with median projection broadly rounded, terminating at about level of broadly rounded ventrolateral margins. Genital style robust in ventral view, inner margin straight in basal quarter, evenly and strongly concave medially, nearly straight in apical quarter; outer margin straight in basal half, concave just before midpoint, convex in apical half, apex broadly rounded.
