Description

Length of male 7.8 mm; female 7.8–9.2 mm. Dorsum yellow with extensive brown markings; pair of spots on crown behind ocelli, anterior band of irregular spots, two pairs of posterior maculae on pronotum and pair of spots on mesonotum black; forewings with brown irroration, veins tinged with red; area just beneath marginal rim of head black, remainder of venter pale yellow. Crown slightly concave in profile, marginal rim relatively thin, forming shelf over frontoclypeus, ocelli well separated from anterior margin. Forewing with supernumerary crossveins in corium and clavus, inner apical cell relatively broad and long but not extended to wing apex. Hind tibial rows PD, AD, and AV with 27, 13 and 17 macrosetae, respectively. Style sinuate in lateral view, gradually widened toward middle, then gradually tapered to apex. Aedeagus with quadrate ventral keel at base in lateral view; shaft slender, tapered, evenly curved dorsad, gonopore apical; unpaired basal process similar in width but longer than shaft, curved dorsad and closely parallel to shaft through most of length, apex slightly twisted and attenuate. Female sternite VII with posterior margin truncate. Second valvulae short and broad, dorsal margin humped beyond midlength, with row of several relatively long, irregular teeth distally, apex acuminate.
