Diagnosis

Colour. Vertex light brown; disc or apical compartment darker. Face mid or dark brown with pale carinae. Pronotum light brown with few darker marks; mesonotum light brown dorsally between lateral carinae, laterally mostly dark brown. Forewing hyaline whitish with a dark mark at apex of clavus and basal of pterostigma, a few dark marks along some crossveins and along veins near apex of forewing; veins light brown; tubercles distinctly contrasting with pale veins; pterostigma pale light brown. Legs light brown. Abdominal sternites light to mid brown. Morphology. Body length: ♂ 4.2 mm, ♀ 4.6 mm. Head: Vertex about 1.4× wider than long; at level of basal emargination about 1.1× wider than at subapical carina; apical and subapical carina u- to v-shaped; median carina of vertex complete; basal compartment about 1.6× longer than apical compartment. Frons 1.2× longer than wide; frons only just visible in dorsal view. Position of maximum width of frons more or less around centre of frontoclypeal suture. Frontoclypeal suture slightly semicircular, bent upwards, median part not reaching lower margin of antennal scape. Median carina of frons and clypeus blunt, rounded. Rostrum reaching hind coxae; apical segment of rostrum almost as long as subapical segment. Thorax: Pronotum moderately wider than head (including eyes). Hind margin of pronotum more or less rectangular. Forewing 4.2× longer than wide; forewing with slightly developed basal emargination; costa with about 29–31 tubercles, tubercles dark, distinctly in contrast with lighter veins; Sc+R+M near basal cell fused, forming a long (more than half of length of basal cell) common stem Sc+R+M; fork of ScRA+RP distinctly basad of fork CuA1+CuA2; position of icu at CuA at same level as apex of clavus; position of icu at CuP distant of apex of clavus; RP apically trifid; MA apically bifid; additional subapical cell between branches of MA absent; nodus of y-vein slightly basad of centre of clavus; vein delimiting subapical cell C4 slightly distad of vein delimiting C5; 9 apical cells. Hind leg: 1st and 2nd tarsomere with 6 apical teeth. Male genitalia: Anal tube asymmetrical in dorsal and caudal view; lateral lobe with lateral margin slightly excavated. Ventromedian process of pygofer trapezoid, medially slightly emarginate, margin darkened. Aedeagus: Phallotheca dorsally with slightly curved spine (a); ventrally with very long, almost straight spine (b); strongly bent spine (c); and short, caudally (towards apex of phallotheca) directed spine (d). Flagellum without sclerotised spines (Löcker 2014).
