Genus Onukigallia Ishihara

Onukigallia Ishihara 1955: 215 , 217. Type-species: Agallia onukii Matsumura , by original designation.

Morphology. Vertex distinctly narrower in middle than next to eyes, not sinuately produced behind eyes. Ocelli closer to eyes than to each other. Pronotum with distinct punctures. Veins especially those on clavus conspicuously elevated, distinct, inner claval vein strongly curved, three anteapical and four apical cells, inner anteapical cell either closed or open behind. Forefemora with intercalary setae forming an arcuate row, row AV with one stout long seta in proximal half. Hind femoral macrosetae 2+1; hind tibial macrosetae PD 10±2, AD 8±1, AV8±1; hind basitarsus with two platellae on distal transverse row.

Male genitalia. Pygofer simple, often with filamentous setae on lateral surface. Subgenital plates covered with long filamentous setae on both upper and lower surface in addition to ventral uniseriate stout setae. Styles with inner arm longer than outer arm, with subapical tooth. Connective broadest in middle, strongly narrowed caudally, longer than broad. Aedeagus long, recurved, without processes; preatrium and dorsal apodeme often well developed. Anal collar process well developed.

Remarks. Onukigallia closely resembles Agallia as both share stout setae on the male subgenital plates. However, the former differs from the latter in having hair-like setae on the male pygofer and subgenital plates and in the structure of the aedegus and subgenital plates. It also closely resembles Formallia from which it differs in possessing setae both dorsally and ventrally on the subgenital plates and also in the shape of the caudal lobe of the male pygofer.

Distribution. China, Japan and Taiwan
