Diagnostic characters. This species differs from other members of the genus by the following characters: coloration—body greenish blue, tegminal margins orange; male terminalia—genital style more slender and elongate than in other species; aedeagus with cephaloventrad process positioned at apical fifth.

Description. Size. Body length 8.3–8.9 mm.

Coloration. Head green blue, with lateral margins slightly yellow; eyes black; ocelli white; apex of antennal segment II yellowish brown; clypeus yellowish brown; thorax greenish blue or faded; legs light brown; tegmina greenish blue, with postclaval, apical and costal margins orange.

Head. Short in dorsal view, about 3.7 times broader than long, narrower than pronotum, anterior margin pointed, lateral margins ridged ( Figs 2 H, 3A). Vertex ( Figs 2 H, 3A) very short, partly concealed beneath anterior margin of pronotum. Frons ( Figs 2 L, 3C) convex, 1.3 times wider than long, lateral margin convex, sinuate near frontoclypeal suture, moderately raised, median longitudinal carina almost full length of frons. Clypeus ( Figs 2 L, 3C) narrower than frons, frontoclypeal suture ( Fig. 3 C) angulated, about 125°. Rostrum long, extending to mesotrochanter. Antennal segment I ring-like, segment II about four times longer than segment I.

Thorax. Thorax ( Figs 2 H, P, 3B) moderately humped. Pronotum ( Figs 2 H, 3A): anterior margin truncate, posterior margin concaved, lateral carinae extending ventrally, near to postocular eminences. Mesonotum ( Figs 2 H, 3A): anterior margin convex, three longitudinal carinae slightly elevated. Metatibia with six or seven spines apically, basal metatarsal segment with six or seven spines apically.

Tegmen ( Fig. 2 D): length about 7.2–7.5 mm, width between costal margin and apex of clavus 3.7–4.2 mm; reticulate apical 2/3; costal margin convex, apical margin rounded to apex of clavus; postclaval sutural margin straight, one subapical line, apical cell slightly longer than costal membrane; costal cell with several transverse veinlets; costal membrane about 1.4 times wider than costal cell at the level of bulla. ScP+R stem short, forked before bulla, RA forked once near midlength of tegmen, branch RP forked slightly apicad of RA fork; MP forked at bulla, branch MP1+2 forked after bulla, MP1 forked near midlength of tegmen, MP2 forked after fork of MP1, MP3+4 forked slightly apicad of branch MP1+2 forking; CuA1 and CuA2 not forked and subparallel, CuP about 2/3 length of tegmen, Pcu and A1 fused in apical portion of clavus.

Male terminalia. Male anal tube ( Fig. 3 D) angulated near midlength, apex acute, basal ventral part with one membranous process produced caudad. Pygofer ( Fig. 3 D) ring-like, anterior margin strongly S-shaped, dorsal margin rounded into posterior margin. Genital style ( Fig. 3 D) slender and elongate, apical third bent up. Phallic complex: periandrium ( Fig. 3 E) tubular, closed basally, open apically with deep split; dorsal margin convex, dorsal lobe small; ventral lobe with long recurved apical process; apex of ventral part acute. Aedeagus ( Fig. 3 F) apically bipartite, dorsal part of apex with small recurved process, lateral part of apex with ear-like lobe, a cephaloventrad process positioned at apical fifth.

Female terminalia ( Fig. 3 G). Female anal segment ( Figs 3 G, H) nearly ovate in dorsal view, apical margin distinctly concave at middle; anal pore situated apical half, paraproct short, about 0.3 times as long as anal segment. Gonoplac short with obtuse posterior margin, central and upper part of disc covered with setae, posterior margin bears two rows of well-developed teeth: shorter in upper part and longer alongside the margin. Gonapophysis IX small, apex cuspidal in lateral view. Anterior connective laminae of gonapophysis VIII stout, broad basally, curved dorsally near middle in lateral view, dorsal margin clearly concave medially, ventral margin bearing four large teeth of different sizes. Sternum VII with posterior margin weakly concave.
