Uniformus robustispinus, Song & Huang, 2023

Song, Yuanyuan & Huang, Min, 2023, Descriptions of two new species of leafhopper genus Uniformus (Hemiptera Cicadellidae: Typhlocybinae: Dikraneurini) from China, Zootaxa 5339 (3), pp. 291-295 : 292

1. Uniformus robustispinus Song & Huang, sp. nov. ( Figs 1–15 )

Measurement. Male, 3.1–3.2mm (including wings).

Description. Color pattern as in Figs 1–6 .

Hind wing vein MP+CuA branched ( Fig. 7 ). Abdominal apodemes reaching 4th abdominal sternite ( Fig. 12 ). Pygofer side prolonged and narrowed subapically with ventral margin of end triangular ( Fig. 10 ). In ventral view, subgenital plate with surface spinose, row of rigid microsetae laterally and row of macrosetae lateroventrally ( Fig. 9 ). Paramere hooked apically and not extended beyond subgenital plate ( Fig. 15 ). Connective with lateral arms short. ( Fig. 11 ). Aedeagal shaft with a lamellate protrusion dorsally on upper half; preatrium with two pairs of processes, subapical processes shorter and smooth, apical processes longer and covered with pore-like indentations, all processes directed laterally ( Figs 13–14 ).

Observed Materials. Holotype: ♁, CHINA, Yunnan Province, Mt. Gongshan , 26-VII-2018, coll. Dongming Wang. Paratype: 1♁, same data as holotype.

Notes. The new species is similar to U. rostellatus in color pattern, but can be distinguished from U. rostellatus by the subgenital plate not extended beyond the pygofer, the shape of which also can be used to distinguish it from U. inclusus , but the new species has different color pattern from U. inclusus .

Etymology. The specific epithet is the Latin compound word “robustispinus”, which refers to the robust apical processes of the aedeagal preatrium.
