Diagnosis

Colour. Vertex mid or dark brown with paler carinae. Frons mid brown, dark brown or black with paler carina (lateral carinae palest near frontoclypeal suture). Post- and anteclypeus usually darker than frons with slightly paler carinae. Pronotum light brown, with dark patches. Mesonotum midbrown, dark brown or reddish brown with concolorous or slightly paler carinae. Forewings light brown, tubercles and veins light or mid brown, concolorous with cells. Pterostigma, crossveins and apical parts of veins often slightly darker. Body and legs light or mid brown. Morphology. Body length: ♂ 5.5–6.1 mm; ♀ 6.7–7.3 mm. Head: Vertex 2.2–2.5 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 as long as wide position of maximum width distinctly dorsad of centre of frontoclypeal suture; lateral carinae of frons in facial view convex, rectilinear apically or convex, evenly rounded. Frontoclypeal suture strongly semicircular, bent upwards, median part just or just not reaching lower margin of antennal scape. Postclypeus with median carina moderately to well developed, sometimes evanescent near frontoclypeal suture. Anteclypeus with median carina moderately developed, evanescent or absent. Rostrum reaching hind coxae. Thorax: Hind margin of pronotum obtusely angled or rectangular. Mesonotum with median carina moderately developed, evanescent near posterior end; lateral carinae moderately developed. Forewing 3.1–3.4 x longer than wide; concavity at costal border absent; costal margin with 12–19 tubercles; fork of ScP+RA and RP slightly 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 absent or present; MP1+2 trifid (rarely bifid); MP3+4 trifid; 10–12 apical cells; 6–7 subapical cells. Hind leg: tibia with 6 apical spines; 1st tarsomere with 9–13 apical teeth and no platellae; 2nd tarsomere with 12 (rarely 13) apical teeth and 10 (rarely 8 or 11) platellae. Male genitalia: Phallotheca narrow, near base with a bifurcate ventral process; phallotheca with spine (a) moderately to strongly curved, arising left lateral; spine (b) almost straight, arising right lateral; spine (b) inserts slightly further down the aedeagus shaft than spine (a) and its tip also reaches further down; in ventral view only small parts of spine (b) and sometimes spine (a) concealed by phallotheca. Aedeagal spines not reaching bifurcate ventral process (Löcker and Holzinger 2019).
