Genus Hemagallia nov.

Type-species: Agallia plotina Distant

Morphology. Small (2.0– 2.7 mm long), robust, brownish to dark brown leafhoppers. Vertex slightly longer medially than next to eyes ( Fig. 7). Two small round areas (coronal calli) near hind margin of vertex, either slightly raised from general surface or sunken, but always darker than ground color. Face wider than long, clypellus slightly broader in middle, apex truncate, genae expanded, deeply sinuate below eyes ( Fig. 8). Ocelli as close to each other as to eyes. Pronotum and scutellum flat ( Fig. 9), posterior half of pronotum with transverse ridges and pits. Face, vertex, anterior half of pronotum and scutellum granular. Forewings almost half as broad as long, apically narrowed and rounded, claval area with fine punctures. Hind wings reduced, lobe-like. Forefemur with intercallary setae aranged in arcuate row, AV row with one seta in distal half stout and long ( Fig. 28). Hind femoral macrosetae 2+1; hind tibial macrosetae PD 8±1, AD 6±1, AV 5, setae on PV not capitate but stout setae alternated by two to four slender setae; hind basitarsus with three rows of setae on plantar suface and two platellae on apical transverse row ( Fig. 35). Male sternal apodemes at base of abdomen well developed.

Male genitalia. Pygofer with caudal lobe rounded, without appendages or processes. Subgenital plates boatshaped. Ninth tergum completely sclerotized. Styles with inner arm greatly exceeding length of outer arm, apically broadened with convex apical margin, ventrally with one tooth, outer arm short, outer margin excavated. Connective broad at base, somewhat T-shaped, apically bilobed, slightly broader than long. Aedeagus with dorsal apodeme robust, well developed, shaft slender, strongly curved, compressed, with subapical gonopore. Anal collar with hook-like appendage.

Female genitalia. Ovipositor with first pair of valvulae slightly arcuate, sculpturing occupying about half distal length dorsally, sculpture of loosely packed alveoli, with dorsal two rows irregular, submargrinal in mid region ( Figs 64, 65). Second pair of valvulae rather straight, with toothed area occpying distal 0.33, teeth of uniform size, ventroapical area toothed ( Figs 66, 67).

Remarks. Hemagallia resembles Anaceratagallia but differs in having reduced hind wings, a smoothly rounded caudal pygofer lobe, exceedingly drawn out and apically broadened inner arm of the style, by the shape of the aedeagus and by the presence of non-capitate setae on row PV of the hind tibia.
