Zhang, Lan & Xing, Jichun, 2020, Description of a new leafhopper species of the genus Watanabella (Hemiptera Cicadellidae, Deltocephalinae) from China, Zootaxa 4808 (3), pp. 539-546 : 541-543

Watanabella curvatua sp. nov.

Figs. 26–36.

Head including eyes slightly wider than pronotum, less angulately produced head. Forewing with some extra branches of vein R along the costal margin and an extra crossvein dividing the outer anteapical cell. Other external features as in generic description.

Male genitalia. Male pygofer with process on inner side relatively long, strongly arched and serrate on distal margin (Fig. 30). Subgenital plate about 2 times as long as wide at base, with 9 long macrosetae along lateral margin, apex extremely narrow, sclerotized (Fig. 32). Aedeagus in lateral aspect long, narrowing towards apex, with a pair of evenly recurved spinelike processes extended to middle of shaft, shaft with numerous spines arranged asymmetrically on both sides (Figs. 33, 34).

Measurement. Length (including tegmen): ♂, 3.9 mm.

Material examined. Holotype: ♂, CHINA: Yunnan Prov., Lushui County, Pianma , 15 June 2011, coll. Yujian Li ( GUGC).

Remarks. This new species is similar to W. montivaga ( Baker, 1924) , but can be distinguished from the latter by the shape of the aedeagus.

Etymology. The new species name is a modification of the Latin word “ curvam ” (curved), referring to the male pygofer side with a curved process on the inner side.
