Diagnosis

Morphology. Head. Vertex with very obtusely angled basal emargination; lateral carinae slightly elevated; length of median carina about 3/4 of distance between basal emargination and subapical transverse carina; apical and subapical transverse carina connected by two small carinae. Frons partly visible in dorsal view; position of maximum width distinctly dorsad of centre of frontoclypeal suture; lateral carinae not elevated; frontoclypeal suture strongly semicircular bent upwards, median part just reaching lower margin of antennal scape. Median carina of postclypeus evanescent or absent, lateral carinae weakly developed. Rostrum very long, surpassing hind coxa (rarely surpassing hind femur). Thorax. Pronotum with median carina; hind margin very obtusely angled. Mesonotum with 2–5 carinae; caudad portion distinctly elongate. Forewing without concavity at costal border; tubercles present in cells and along veins; Sc+R+M fused, forming short common stem; fork Sc+R distinctly distad of fork CuA1+CuA2; icu distad of apex of clavus; R apically bifid; MA apically bifid; MP apically trifid; MP1+MP2 (= M3+4) forking distinctly basad of MA1+MA2 (= M1+2); nodus of Y-vein distinctly distad of centre of clavus; 9 apical cells. Hind leg: tibia with 2 lateral spines and 6 apical teeth; 1st tarsomere with 5 apical teeth; 2nd tarsomere triangularly shaped with 5–6 apical teeth; tarsomeres without platellae. Abdomen. Rows of trichobothria present on sternites. (Löcker et.al. 2006)
