description: Risefronta Li & Wang
Risefronta Li & Wang 2001: 518. Type species: Risefronta albicincta Li & Wang, by original designation.
Shining black with pale yellow markings on scutellum, hyaline areas on forewing and legs pale yellow.
Robust leafhoppers measuring 6.0–7.0 mm long. Crown declivous anteriorly, slightly depressed on either side of median carina, with marginal and submarginal carinae, these forming pentagon near apex divided medially by median carina, sparsely punctate, polished. Ocelli in depressions below anterior carinae of crown. Eyes prominent, posteriorly encroaching on to anterolateral angles of pronotum. Frontoclypeus overhanging clypellus, median keel angled at lower margin of frontoclypeus, muscle impressions ridged and punctate. Clypellus broad at base narrowed apically, sparingly punctate. Antennae in shallow cavities, antennal ledge prominent. Gena and lorum punctate. Face with sparse setae. Pronotum convex, transversely rugose, punctate without carinae or depression, lateral margin carinate, anteriorly produced almost to 0.66 of length of eye, posterior margin almost straight with lateral oblique margins. Exposed mesonotum either as long as or slightly longer than pronotum, mesoscutum irregularly wrinkled but basal triangles shagreen. Scutellum with lateral and posterior margins smooth. Forewings coriaceous, punctate in basal 0.66, R1 arising at origin of R 2+3 and R 4+5. Fore femora with two elongated setae on row AV, remaining hair-like, setae on row IC hair-like in a curved lines, AM row of setae small with AM1 occupying its normal postion and stout. Hind femur distal macrosetae 2+2+1. Hind tibial macrosetae AD 12±1, PD 23±2 and AV 16±2. Apical transverse row of basitarsomere with three setae in place of platellae.
Male pygofer lobe in lateral view more or less rounded, with a few dorsal marginal prominent setae and patch of short fine setae near posterodorsal angle, ventral process thin, slightly exceeding dorsal margin. Subgenital plate foot-shaped, with both hair-like and macrosetae. Style stout, with subapical lateral region angularly produced, apophysis foot-shaped with heel well developed and toe drawn out into long process. Connective Y-shaped, with stem longer than arms. Aedeagus with well developed more or less quadrangular dorsolateral lobes, shaft well developed, with ventral marginal angular projection in lateral view, gonopore, apical, dorsal apodeme plate-like. Segment X large, tubular, pigmented and slightly exceeding posterior margin of pygofer, without processes.
Female with pregenital sternite posteriorly convex. First pair of valvulae slightly curved, dorsal sculptured area angularly expanded, with strigate sculpture extending to dorsal margin occupying distal 0.33. Second pair of valvulae rather straight, with prominent teeth in distal 0.33 distance, each tooth well separated without secondary dentition.
Remarks. This is a robust species with peculiar head. The crown is produced forward with the median carina dissecting a polygon on the anterior part and the frontoclypeus is greatly swollen and overhanging the clypellus. This genus is recorded for the first time from the Indian subcontinent.
