Genus Anaceratagallia Zachvatkin Status revised

Anaceratagallia Zachvatkin, 1946: 159–161 . Type-species: Agallia venosa Fallén , by original designation.

Color. Brown with two spots on vertex, two on anterior margin of pronotum and at base of scutellum, black. Pronotum often with lateral triangular and median spindle-shaped dark brown patches ( Fig. 3).

Morphology. Robust, wedge-shaped leafhoppers. Vertex longer medially than next to eyes, hind margin evenly rounded. Face and vertex shagreened, transclypeal sulcus complete, gena behind eyes sinuate. Pronotum coarsely and transversely irregularly rugose. Forewing venation prominent with four apical and three anteapical cells, inner anteapical cell closed posteriorly by cross vein ( Fig. 14). Forefemora with intercalary (IC) setae forming arched row, antero-ventral (AV) row with one stout, long prominent and two subprominent setae ( Fig. 23). Hind tibial macrosetae PD 9±1, AD 7±1, AV 5±1. Hind basitarsus with two platellae on distal transverse row.

Male genitalia. Pygofer well sclerotized, caudal lobe produced ventrally into spine-like process or triangular expansion with acute ventral angle ( Figs 100, 106, 123). Subgenital plates together boat-shaped, with short macrosetae arranged in mesal submarginal row. Styles with inner arm longer than outer, usually apically narrowed with subapical tooth. Aedeagus without long processes, often with denticles, dorsal apodeme well developed, preatrium short, gonopore subapical. Anal collar process well developed.

Female genitalia. First pair of valvulae with papillose sculpturing ( Figs 41, 42), sculpturing in middle section submarginal, dorsal two rows not aligned, rest aligned with distinct interspaces, dorsal sculpture on 0.75 length. Second pair of valvulae with dorso-apical margin angularly elevated about distal 0.25, teeth smooth, without denticles, ventroapical area serrated ( Figs 43, 44).

Distribution. Predominantly a Palaearctic genus but also distributed in the Afrotropical and Oriental regions.

Remarks. Anaceratagallia closely resembles Bergallia Oman , Aceratagallia Kirkaldy , Hemagallia gen. nov. and Nandigallia gen. nov. (see below). Nast (1972), Ossiannilsson (1981) and Oman et al. (1990) treated this genus as a junior synonym of Agallia without justification. Anufriev & Emeljanov (1988) however, considered Anaceratagallia as a genus distinct from Agallia . The structure of head, pronotum, forewing venation, pygofer, aedeagus and style distinguish this genus from Agallia . The subgenital plates in Anaceratagallia and Nandigallia gen. nov. are boat-shaped; however, they differ in the structure of the inner arm of the style, which is broad in Nandigallia and narrowed in Anaceratagallia .
