Diagnosis

Colour. Head mid brown, dark brown or black with paler carinae; post- and anteclypeus often slightly darker than frons. Pronotum light brown, often with darker patches. Mesonotum mid or dark brown with concolorous or paler carinae. Forewings light brown, tubercles and veins light brown, concolorous with cells. Pterostigma, crossveins and apical parts of veins often slightly darker. Legs light or mid brown, abdominal sternites usually darker. Morphology. Body length: ♂ 5.1–6.4 mm; ♀, 6.4–6.9 mm. Head: Vertex 2.1–3.0 x wider than long; median carina of vertex covering 1/3–3/4 of basal compartment of vertex; absent in apical compartment. Frons 1.0–1.2 x longer than wide; position of maximum width more or less around centre of frontoclypeal suture or distinctly dorsad; lateral carinae of frons in facial view convex, rectilinear apically or convex, evenly rounded. Frontoclypeal suture strongly semicircular, bent upwards, median part reaching at least lower margin of antennal scape. Postclypeus with median carina well developed or evanescent. Anteclypeus with median carina moderately developed or evanescent. Rostrum reaching hind coxae. Thorax: Hind margin of pronotum rectangular. Mesonotum with median carina moderately developed, evanescent near posterior end; lateral carinae moderately developed. Forewing 3.1–3.8 x longer than wide; concavity at costal border absent; costal margin with 8–12 tubercles; fork of ScP+RA and RP basad, slightly distad or at same level as fork CuA1 and CuA2; tubercles of forewing dark or pale, concolorous with veins; ScP+RA apically bifid or unforked; RP trifid; additional subapical cell between branches of MP1 and MP2 present; MP1+2 trifid; MP3+4 trifid (rarely bifid); 11–12 apical cells; 7 subapical cells. Hind leg: tibia with 6 apical spines; 1st tarsomere with 8–9 (rarely 10) apical teeth and no platellae; 2nd tarsomere with 10–11 (rarely up to 13) apical teeth and 8–9 (rarely up to 11) platellae. Male genitalia: Phallotheca near base with a bifurcate ventral process at the end of a long ventral ridge; left lateral with a sclerotised ridge; phallotheca ventrally with a strongly curved spine (a) with a large base, tip of spine (a) directed right laterad; right lateral with a long, straight spine (b), in ventral view mostly concealed by phallotheca.
