Li, Hu, Dai, Ren-Huai & Li, Zi-Zhong, 2016, The leafhopper genus Onukigallia Ishihara, 1955 with descriptions of two new species from southern China (Hemiptera, Cicadellidae, Megophthalminae, Agalliini), ZooKeys 622, pp. 85-93 : 89-90

Taxon classification Animalia Hemiptera Cicadellidae

Onukigallia tumida sp. n. Figures 6-8, 20-24

Measurement.

Body length including tegmina in repose: ♂, 4.48-4.50 mm.

Description.

Body coloration and external morphology. Body (Figs 6-7) relatively darker and more slender than Onukigallia neoonukii sp. n. Face (Fig. 8), anteclypeus distal half not black; gena with black macula medially. Pronotum 2.1 × wider than broad. Scutellum with end and lateral angles pale, 1.1 × longer than pronotum and 1.3 × wider than long. Other color pattern and external morphology similar to Onukigallia neoonukii sp. n.

Male genitalia. Pygofer (Fig. 20), basally broad, in lateral view, lobe strongly narrowed, with dorsal and ventral margins parallel, apex round, ventrocaudal surface of lobe with hairlike setae. Valve broader than long. Subgenital plates (Fig. 20) widened, exceeding pygofer side, surface with filamentous setae, and uniseriate stout setae ventrally. Anal collar process simple, relatively stout, basally broad, then tapered to acute tip twisted caudally. Style (Fig. 21) typical of genus, inner arm 2.0 × longer than outer arm, slightly inflated in middle, with clear triangular process medially on outer margin, apex blunt. Connective (Fig. 22) anterior margin with medial lobe, caudal margin prominent medially, lateral margins slightly expanded near apex, and clearly excavated near base. Aedeagus (Figs 23-24), in lateral view, broad basally, curved dorsally, shaft with small hump near midlength on dorsal margin, ventral margin below gonopore slightly depressed, apex subacute; in ventral view, shaft expanded laterally on lateral margins near base, then tapered, subapex slightly widened and apex round; gonopore apical on ventral margin; dorsal apodeme elongate, tip expanded in bilateral direction.

Female genitalia. Unknown.

Material examined.

HOLOTYPE: ♂, CHINA: Hubei Province, Shennongjia, 17.VII.2013, collected by Chang Zhi-Min. PARATYPES: 1 ♂, CHINA: Hunan Province, Badagongshan, 03.VIII.2013, collected by Li Hu.

Distribution.

China (Hubei and Hunan Provinces).

Remarks.

This new species is similar to Onukigallia fanjingensis Zhang & Li but can be distinguished from the latter by the different shape of the pygofer lobe and the anal collar process, the aedeagal shaft with an apophysis on its dorsal margin near the base in lateral view, and expanded laterally near base in ventral aspect.

Etymology.

The new species name is derived from the Latin word “tumidus”, refers to the swollen structure of aegeagal shaft.
