Description

Length of male 8.6–9.4 mm; female 10.7–11.4 mm. Dorsum olivaceous, with dark markings limited to pair of round black spots on crown posterad of ocelli, anterior band of irregular spots on pronotum and diffuse maculae at forewing apex; venter unmarked except for diffuse brown spots on femora and tibiae. Forewing with few or no supernumerary crossveins, inner apical cell extremely narrow and not extended to wing apex. Crown flat in profile, marginal rim relatively thick, not forming shelf over frontoclypeus. Hind tibial rows PD, AD and AV with 24, 12 and 11 macrosetae, respectively. Style apophysis slender and of nearly same width throughout, apex curved slightly dorsad and tapered to sharp tip with dorsal preapical angle. Aedeagus with atrium V-shaped, with poorly sclerotized plate connecting arms of V, shaft curved strongly dorsad, with pair of acuminate lateral spines arising laterally near midlength and extended nearly to apex, closely parallel to shaft and straight in posterior view, shaft parallel-sided in posterior view, shaft apex tapered and distinctly emarginate, gonopore apical. Female sternite VII with posterior margin truncate. Second valvulae moderately slender, slightly broadened from base to near apex, then tapered, dorsal margin with numerous close-set, irregular teeth in distal half.
