Diagnosis. The species differs from other members of this genus by the following characters: mesonotum ( Fig. 3View FIGURES 1–10) with 3 carinae, apical fourth of aedeagus ( Figs 7View FIGURES 1–10, 12, 19View FIGURES 11–25) with a pair of cephalad and 3-branched processes, dorsal apical part of aedeagus without tooth.

Description. Size. Body length 8.2–9.8 mm.

Coloration. Overall color dark brown or black; head mottled brown, margins of frons slightly darker, two pairs of black spots—the first pair at the anterior margin of head, the second pair at the lateral margins of head, clypeus with oblique stripes; eyes black, ocelli red; pronotum and mesonotum dark brown or black; tegmina dark brown with darker veins, Y-stem of clavus black.

Head. Head ( Fig. 3View FIGURES 1–10) including eyes narrower than pronotum; vertex wider than long, rounded into frons; anteri- or margin convex or truncate; lateral margins raised; posterior margin shallowly emarginate, disc depressed, almost covered by anterior margin of pronotum. Frons wider than long, widest at midline, lateral margins carinate, median longitudinal carina strongly raised at dorsal portion, T-shaped, slightly weak at ventral portion; frontoclypeal suture shallowly convex, clypeus convex ( Fig. 5View FIGURES 1–10). Rostrum extending to metatrochanter. Ocelli present. Antennae very short ( Fig. 4View FIGURES 1–10).

Thorax. Pronotum ( Figs 3, 4View FIGURES 1–10) with anterior margin evenly convex, median carina weakly visible, postocular eminences conical. Mesonotum ( Fig. 3View FIGURES 1–10) with anterior margin convex, disc flat with three carinae or sometimes in form of three eminences in anterior part. Metatibia with six spines apically; metatarsal basal segment with nine or ten spines apically.

Tegmen ( Fig. 2View FIGURES 1–10). Tegmina elongate, about 2.2 times longer than wide, costal membrane wider than costal cell at the level of bulla ( Fig. 2View FIGURES 1–10); costal margin sinuate, apical margin convex. Three veins arising (Scp+R, Mp, CuA) from basal cell; Scp+R stem very short, ScP+RA crossing raised bulla; Y-stem of anal veins short and highly raised; one subapical line present.

Male terminalia. Anal tube ( Figs 6, 9View FIGURES 1–10) in lateral view almost straight, apex bent down and inflated, with shallow incision in dorsal view. Pygofer ( Fig. 6View FIGURES 1–10) ring-like. Genital style ( Fig. 6View FIGURES 1–10) almost isosceles triangular, ventral margin strongly convex, apical margin oblique, as long as dorsal margin, with single process at dorsocaudal portion. Phallic complex ( Figs 7, 8, 10View FIGURES 1–10, 17, 20, 23View FIGURES 11–25) slightly arched. Periandrium ( Figs 11, 13, 15, 18, 21, 24View FIGURES 11–25) tubular, dorsal part membranous, dorsolateral emargination shallow; lateral emargination moderately wide; dorsal lobe produced caudad, lateral lobe with narrow 3-branched process, ventral lobe slender, apex acute in ventral view. Aedeagus ( Figs 12, 14, 16, 19, 22, 25View FIGURES 11–25) bipartite; a pair of long cephalad, 3-branched processes at apical fourth of dorsal portion; each side of apex without process; lateral portion with an even prominence beneath a hooked process.

Female terminalia. Anal segment ( Fig. 31View FIGURES 26–35) small, oval in dorsal view, apex slightly concave; anal foramen in basal half. Gonocoxa VIII ( Figs 28, 34View FIGURES 26–35) nearly triangular, apically with 5–7 teeth; dorsal margin evenly concave or straight; ventral margin moderately convex. Posterior connective laminae of gonapophysis IX ( Figs 29, 32View FIGURES 26–35) nearly slender triangular, apically acute; gonospiculum situated at base of gonapophysis IX ( Figs 30, 33View FIGURES 26–35), apex angled in lateral view, basal margin angled in dorsal view. Gonoplac ( Figs 27, 35View FIGURES 26–35) nearly trapezoidal, ventral margin evenly concave; apical and dorsal margins convex and sclerotized, with two rows of strong teeth in posterior view; external row with 15–16 teeth along dorsal margin to the apex of ventral margin; internal teeth relatively small comparing to the lateral teeth, arranged irregulary, in number of 12–14, mainly located on the dorsal margin to the upper half of posterior margin; long setae on the dorsal part of posterior margin present.
