Diagnosis

Colour. Head and pronotum mid or dark brown with distinctly contrasting pale carinae. Mesonotum mid or dark brown laterally, central area between carinae sometimes paler; carinae pale. Forewings light brown often with a weakly to moderately developed pattern of 6 mid brown spots (3 on each wing: near y-fork in claval area, near CuA1 and CuA2 fork and on MP basad of MP1+2 andMP3+4 fork); forewing sometimes with darker patches near crossveins and apex of wing; forewing veins light to mid brown, tubercles concolorous with veins; pterostigma light to mid brown. Body and legs light or mid brown. Morphology. Body length: ♂ 6.2–6.7 mm; ♀, 8.7–9.6 mm. Head: Vertex 2.1–2.2 x wider than long; median carina of vertex covering entire length of basal compartment of vertex; evanescent in apical compartment. Frons 1.0 x as long as wide; position of maximum width more or less around centre of frontoclypeal suture or distinctly ventrad; lateral carinae of frons in facial view slightly 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 well developed. Rostrum by far not reaching hind coxae. Thorax: Median carina of pronotum extremely well developed and very long. Hind margin of pronotum obtuse. Mesonotum with median and lateral carinae well developed. Forewing 3.3–3.6 x longer than wide; concavity at costal border well developed; costal margin with 1–2 indistinct tubercles; fork of ScP+RA and RP slightly to moderately basad of or almost at same level as fork CuA1 and CuA2; tubercles of forewing dark or pale, concolorous with veins; ScP+RA apically bifid; RP trifid; additional subapical cell between branches of MP1 and MP2 absent or present; MP1+2 trifid; MP3+4 bifid or trifid; 11–12 apical cells; 6 subapical cells. Hind leg: tibia with 6 (rarely 7) apical spines; 1st tarsomere with 11–13 apical teeth and 6–8 platellae; 2nd tarsomere with 12 (rarely 13) apical teeth and 10 (rarely 11) platellae. Male genitalia: Phallotheca below midlength with a bifurcate ventral process; left lateral with a long, curved spine (a); right lateral with long, curved spine (b), in lateral view spine (b) not reaching down as far as spine (a) because it is more strongly curved (Löcker and Holzinger 2019)
