Sungallia gen. nov.

Type-species: Sungallia truncata sp. nov.

Brown with black markings.

Small, robust, brachypterous leafhoppers. Head wider than pronotum. Crown of head longer medially than next to eyes, granulated, 3.5 times as wide as median length of crown. Face slightly wider than long, transclypeal sulcus not complete medially. Antennal ledges oblique. Clypellus long, exceeding genal curve. Lora elongate. Ocelli dorsad of imaginary line across upper margin of eye in facial view, slightly closer to each other than to adjacent eyes. Pronotum flat, 1.25 as wide as median length, 1.8 times as long as crown, transversely rugose, with one callus on either side of median line, closer to front margin than to hind, anterior margin slightly arcuate, posterior margin almost straight. Scutellum slightly shorter than pronotum, transversely rugose. Forewings poorly developed exposing three complete tergites (in addition to genital capsule), apical margin truncate with rounded lateral and mesal angles, venation rudimentary. Fore femora with well-developed intercalary row of setae; anteromedian row of setae well-developed and arranged in two groups, distal two setae AV1 and AV2 ventrad to intercalary row, remaining group of three setae more proximal ( Fig. 24 H). Hind femoral macrosetae 2+1; hind tibial macrosetae PD 8±1, AD 7±1, AV 6±1; metabasitarsus with two platellae on apical pecten.

Male genitalia. Pygofer with ventral hook-like process arising at midlength. Anal collar process not developed, anal segment small. Subgenital plates and valve fused, former separate, rather quadrangular, lacking macrosetae. Style robust, inner fork of apophysis about as long as outer fork. Connective broader than long, with bilobed apex, dark pigmented. Aedeagus with well developed dorsal apodeme and preatrium. Shaft elongate, rather compressed, with apical processes; gonopore apical.

Distribution. China (Yunnan).

Etymology. The generic name is derived by combining two words Sun + Agallia , gender feminine.

Remarks. This brachypterous genus can be easily distinguished from all other Old World agalliine genera by the presence of a hooklike ventral process of the male pygofer.
