+), often distinctly patterned and pale yellow in coloration. Head narrower than pronotum, somewhat anteriorly produced. Vertex relatively narrow and elongated (length nearly 2x width), disc concave, sometimes bearing a short median carina, anterior margin nearly truncate bearing transverse apical carina, lateral margins somewhat foliate, nearly straight (weakly diverging basad); posterior margin angulately incised (sometimes more broadly), subapical transverse carina meeting before head apex connecting with apical transverse carinae by a pair or longitudinal carina forming a median areolet (and lateral triangular areolet), median areolet contiguous with areolet formed by fork of median carina of frons. Frons relatively elongated (and often medially darkened with a pale outer margin), frons plus clypeus collectively forming an elongated diamond shape (both bearing a median carina); lateral margins foliate, expanding to below level of antennae then incurved; lower lateral part of frons bearing a variably defined fossa on each side. Frontoclypeal suture strongly bending to excise quadrate region from within frons. Median ocellus distinct above frontoclypeal suture, lateral ocelli near anteroventral margin of eyes. Eyes rounded, weakly emarginate near antennae. Antennae short (nearly hidden from frontal view by lateral margins of face), scape ring-like, pedicel bulbous bearing sensory plaques. Rostrum long, exceeding hind trochanters.
Pronotum short, median carina present, lateral carinae of each side following hind margin of eyes; posterior margin deeply excavate in obtuse angle. Mesonotum broader than long, often marked with three dark longitudinal stripes, with five carinae, intermediate carinae often less conspicuous. Legs slender and elongated, hind tibia with 3 (rarely 2) lateral teeth, apical ornamentation usually 6(3+3 or 5+1)/7/7. Tegmina transparent or weakly embrowned, veins strong and dark, setae-bearing tubercles inconspicuous; elongated, weakly spatulate; composite vein ScP+
