Diagnosis

Colour. Head mid brown, dark brown or black with paler carinae. Pronotum light brown, with darker patches. Mesonotum mid to dark brown with paler carinae; central area of mesonotum (in between carinae) often lighter coloured. Forewings light brown or whitish sometimes with a few dark patches, veins light brown or whitish, concolorous with cells, tubercles dark, in distinct contrast with lighter coloured veins. Pterostigma, crossveins and apical parts of veins often slightly darker. Body and legs light brown or mid brown. Morphology. Body length: ♂ 5.6–6.9 mm. Head: Vertex 2.1–2.7 x wider than long; median carina of vertex covering 1/3–3/4 of basal compartment of vertex; absent in apical compartment. Frons 1.0–1.1 x longer than wide; position of maximum width more or less around centre of frontoclypeal suture or slightly dorsad; lateral carinae of frons in facial view convex, rectilinear apically or sinuate, s-shaped. Frontoclypeal suture strongly semicircular, bent upwards, median part reaching at least lower margin of antennal scape. Postclypeus with median carina well developed. Anteclypeus with median carina moderately developed or evanescent. Rostrum reaching or surpassing hind coxae. Thorax: Hind margin of pronotum acutely angled or rectangular. Mesonotum with median carina weakly to moderately developed, evanescent near posterior end; lateral carinae moderately developed. Forewing 2.8–3.4 x longer than wide; concavity at costal border absent; costal margin with 19–22 tubercles; fork of ScP+RA and RP distinctly basad of fork CuA1 and CuA2; tubercles of forewing dark, distinctly contrasted to paler coloured veins; ScP+RA apically bifid; RP trifid (rarely 4 branches); additional subapical cell between branches of MP1 and MP2 absent; MP1+2 trifid (rarely bifid); MP3+4 trifid; 11–12 apical cells; 6 subapical cells. Hind leg: tibia with 6 (rarely 7) apical spines; 1st tarsomere with 10–12 (rarely 13) apical teeth and 5–6 (rarely up to 9) platellae; 2nd tarsomere with 9–11 apical teeth and 7–9 platellae. Male genitalia: Phallotheca highly sclerotized, especially on left lateral side where it forms a ridge that ends in a bifurcate ventral process near base of phallotheca; phallotheca wide in apical half, slightly narrower in basal half; phallotheca asymmetrical, especially near bifurcate ventral process; phallotheca left lateral with a long spine (a), strongly curved in dorsal view, almost straight in lateral view, entirely concealed by phallotheca in ventral view (basal part of the spine concealed by a very thin, transparent layer of the phallotheca); right lateral with a long, almost straight spine (b) Löcker and Holzinger 2019.
