Diagnosis

Colour. Vertex light brown (rarely darker); face mid-to-dark brown with paler carinae (i.e. lateral carinae), disc of frons sometimes paler near apical carina. Pronotum light brown; mesonotum dark brown. Forewing hyaline colourless with more or less extended light or mid brown marks; veins and tubercles concolorous with cells, crossveins sometimes darker; pterostigma whitish. Legs light brown. Abdominal sternites mid-to-dark brown. Morphology. Body length: ♂ 4.1–5.3 mm, ♀ 4.7–5.4 mm. Head: Vertex 1.7–2.2× wider than long; at level of basal emargination 1.0–1.3× wider than at subapical carina; apical and subapical carina v-shaped; median carina of vertex absent; basal compartment of vertex 1.4–3.0× longer than apical compartment. Frons 1.2–1.6× longer than wide; frons just not or only just visible in dorsal view. Position of maximum width of frons more or less around centre of frontoclypeal suture. Frontoclypeal suture slightly semicircular, bent upwards, median part not reaching lower margin of antennal scape. Rostrum surpassing hind coxae; apical segment of rostrum almost as long as subapical segment. Thorax: Pronotum about same width to moderately wider than head (including eyes). Hind margin of pronotum acutely angled or rectangular. Forewing 3.5–4.0× longer than wide; forewing with welldeveloped basal emargination; costa with about 30–36 tubercles, tubercles concolorous with veins; Sc+R+M near basal cell fused, forming a short or long common stem Sc+R+M; fork of ScRA+RP slightly to distinctly basad of fork CuA1+CuA2; position of r-m distad of fork MA+MP; transverse veinlet M3+4 to Cu1a inserting at M3+4 basad of r-m; position of icu at CuA basad of apex of clavus; position of icu at CuP more or less at same level as apex of clavus; RP apically trifid; MA apically trifid; additional subapical cell between branches of MA absent; nodus of y-vein slightly basad of centre of clavus; vein delimiting subapical cell C4 distinctly distad of vein delimiting C5; 10 apical cells. Hind leg: 1st tarsomere with 6 apical teeth; 2nd tarsomere with 7 apical teeth. Male genitalia: Anal tube slightly asymmetrical in dorsal and caudal view; lateral lobe rectangular (slightly widening towards apex) in lateral view. Ventromedian process of pygofer trapezoid, uniformly coloured. Aedeagus: Phallotheca with a large spine (a) bearing a short, very slender spine (b); apex of spine (a) serrated or branched one or more times; phallotheca ventrally with a small, transverse, sclerotised ridge and a large, sclerotised ridge bearing a pair of curved, parallel spines (c). Flagellum sclerotised, unarmed. (Löcker 2014).
