Diagnosis

Colour. Vertex dark brown or black with pale carinae (sometimes apical compartment of vertex paler than basal compartment). Face dark brown to black, median carina concolorous or slightly paler; lateral carinae very pale. Pronotum light brown, laterally with slightly darker patches. Mesonotum light brown apart from dark brown to black central area of mesonotum (in between carinae), often extreme lateral parts of mesonotum dark brown to black. Forewings light brown, tubercles and veins concolorous light brown (rarely mid brown). Legs brown, dark near base, light near apex, body mid to dark brown. Morphology. Body length: ♂ 5.9–6.4 mm; ♀ 7.3 mm. Head: Vertex 2.4–2.6 x wider than long; median carina of vertex covering 1/4–3/4 of basal compartment of vertex; absent in apical compartment. Frons 1.2 x longer than 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 slightly semicircular, bent upwards, median part just not reaching lower margin of antennal scape. Postclypeus with median carina well developed. Anteclypeus with median carina moderately developed or evanescent. Rostrum surpassing hind coxae. Thorax: Hind margin of pronotum obtusely angled, acutely angled or rectangular. Mesonotum with median carina moderately developed, evanescent near posterior end; lateral carinae moderately to well developed. Forewing 2.9–3.4 x longer than wide; concavity at costal border absent; costal margin with 20–34 tubercles; fork of ScP+RA and RP basad 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 (C3a in Fig. 28H) between branches of MP present; MP1+2 and MP3+4 bifid or trifid; 11 apical cells; 6–8 subapical cells. Hind leg: tibia with 6 (rarely 7) apical spines; 1st tarsomere with 8 apical teeth and no platellae; 2nd tarsomere with 9 apical teeth and 7 platellae. Male genitalia: Phallotheca symmetrical, with two long spines (a,b) reaching a bifurcate ventral process just below midline of phallotheca. In ventral view basal half of spines (a,b) covered by phallotheca. In lateral view spines (a,b) straight, apart from a strong bend halfway through the spine at which point the spine reaches its maximum width (Löcker and Holzinger 2019).
