Dai, Wu & Zhang, Yalin, 2012, Taxonomic revision of the leafhopper tribe Agalliini (Hemiptera: Cicadellidae: Megophthalminae) from China, with description of new taxa, Zootaxa 3430, pp. 1-49 : 22

Skandagallia gen. nov.

Type-species: Skandagallia dietrichi sp. nov.

Ground color light brown with dark brown and black markings.

Small, robust, brachypterous leafhoppers. Head medially longer than next to eyes, wider than pronotum; slightly produced medially, crown 2.5 times as wide as long; face slightly wider than long. Transclypeal sulcus interrupted in middle, antennal ledges oblique, clypellus widest in middle, lora elongate, ocelli on dorsal area slightly above imaginary line joining upper margin of eyes in facial view, closer to adjacent eye than to each other. Crown rounded to face. Face and crown granulate. Pronotum 1.4 times as long as head, 2.2 times as wide as median length, rather flat with one callus on either side of median line. Surface transversely rugose, anterior margin slightly rounded, posterior margin inwardly angulately curved. Scutellum flat, 0.75 times as long as pronotum, granulate. Forewings poorly developed, exposing four complete abdominal tergites in addition to genital capsule, caudally truncate with rounded lateral and mesal angles, venation obscure. Fore femora with intercalary row of setae well-developed; anteroventral seta AV 1 in line with intercalary seta and AV2 thickened ( Fig. 23 A). Hind femora with 2+1 macrosetae; hind tibiae PD 7±1, AD 7, AV 5 setae; metabasitarsus with 2 platellae on apical transverse row of setae ( Fig. 21 C).

Male genitalia. Pygofer with dorsal margin declivous posteriorly, dorsal margin sclerotized and pigmented, produced with posteriorly directed pointed process. Valve broader than long. Subgenital plates fused with each other at base, triangular, extending posteriorly beyond pygofer lobe, without macrosetae. Anal collar simple, without process. Styles robust, anterior stem rather broad, both inner and outer forks of apophysis equal in length, inner fork gradually slightly widened, with truncate apex. Connective heavily pigmented, longer than broad, caudal apex bilobed. Aedeagus with well-developed bilobed dorsal apodeme, each lobe divergent, shaft broad at base, with subapical pair of laterally divergent slender process and with triangular platelike expansion beyond apical gonopore.

Distribution. China (Yunnan).

Etymology. The genus name is formed by combining the Sanskrit word Skanda (to jump) + Agallia , gender feminine.

Remarks. Skandagallia and Sungallia gen. nov. (see below) are brachypterous genera as in the case of Gunhilda Distant , and Nandigallia Viraktamath wherein both brachypterous and mactopterous forms are found. Skandagallia differs from the other genera in having a posteriorly declivous male pygofer ending in an acute process as in the case of Anaceratagallia . It differs from Anaceratagallia in the structure of the style, connective and subgenital plates.
