Yang, Liyuan & Zhang, Yalin, 2015, Review of the leafhopper genus Oncopsis Burmeister (Hemiptera: Cicadellidae: Macropsinae) in China with descriptions of two new species, Zootaxa 3936 (3), pp. 421-428 : 423-424

Oncopsis (Oncopsis) latusoid sp. nov.

( Figs. 1 A–D, 2)

Description: Length. ♂, 4.3–4.4 mm.

Coloration. Body black ( Fig. 1 A). Face black. Ocelli and eyes red brown ( Fig. 1 D). Pronotum, mesonotum and scutellum black ( Fig. 1 C). Forewing dark, outer margin brown to pale brown ( Fig. 1 B).

Morphology. Head including eyes slightly wider than pronotum. Pronotum slightly declivous anteriorly, with roundly produced anterior margin and slightly concave posterior margin. Scutellum about 1.5 times longer than pronotum, with curved transverse suture at the middle section. Face slightly longer than wide, decorated with obvious notches. Ocelli situated about 3 times as far from midline of face as from eyes. Lower part of frontoclypeus expanded. Forewing with three anteapical cells.

Male genitalia. Pygofer broad, slightly eglongate, caudally truncated. Subgenital plate long, slightly incurved, decorated with several macrosetae ( Fig. 2 A). Connective small, with fingerlike protrusion in middle between dorsally bent arms ( Figs. 2 D, E). Aedeagus laterally compressed, tapered from base to the end, gonopore apical ( Figs. 2 B, C). Style parallel-margined, with blunt end ( Fig. 2 F). Dorsal connective S-shaped, lower part much shorter than upper, bearing caudal forked process. Upper branch longer with serrated margins, lower one shorter with inner margin serrated ( Fig. 2 G).

Female unknown.

Material examined. Holotype: ♂, China: Yunnan Province, Mengxiu, 14 June 2013, coll. Xue Qingquan; Paratypes: 2♂, same data as holotype.

Diagnosis. This new species resembles Oncopsis furca Liu and Zhang but may be distinguished from the latter by the shape of the dorsal connective hook and the body coloration.

Etymology. This new species epithet derived from the Latin word “latus” and “-oid”, referring to the blunt ended style.
