Jiao, Meng & Yang, Maofa, 2020, Uniformus, a new genus of Dikraneurini (Hemiptera: Cicadellidae: Typhlocybinae) from China, with description of two new species, Zootaxa 4868 (4), pp. 596-600 : 597

1. Uniformus rostellatus sp. nov. (Fig A)

Description. Length: male 3.2–3.3mm

Body (Figs A. 1–6) yellow; crown and pronotum white-yellow, one orange longitudinal V shaped mark extend to posterior margin of pronotum; area of frohntoclypeus brown; forewing(Figs A. 1.2.7) with oblique thin transverse orange band in middle ending at dark red macula on costal margin, two thin longitudinal stripes extended distad from transverse band to bases of apical cells, apical cells smoky with small grey spots at base; hind wing (Figs A. 8) transparent.

Male abdomen (Figs A. 9) with apodemes extending to sternum V. Pygofer side (Figs A. 10.11) broad, with row of short, stout setae along distal margin. Subgenital plate (Figs A. 10.12)long, surpassing pygofer side, with short lobe extended posterolaterad near midlength of lateral margin, bordered medially by short setae, several macrosetae along lateral margin near middle, tapered distal section bent slightly dorsad.

Paramere (Figs A. 14) moderately long and thin, apex hooked. Connective (Figs A. 13.14) lamellate, two arms short. Aedeagus (Figs A. 13.14), dorsal apodeme developed; preatreium large, with two pairs of processes, basal pair very long, smooth, curved, encircling aedeagus shaft, bent dorsad distally, distal pair moderately shorter, extended posterolaterad beyond apex of shaft and with denticulate apices. Aedeagus shaft slender and straight, inflated at base, with tuft of apical microtrichia and course preapical denticuli. Gonopore apical.

Type material. Holotype, 1♂, CHINA: Yunnan Province, Lvchun .. 13. VIII. 2014, collected by Liu Yangyang. Paratype, 1♂, CHINA: Yunnan Province, Lvchun.. 13. VIII. 2014, collected by Liu Yangyang. Paratype, 1♂, CHINA: Yunnan Province, Pingbian. H, 2044m. 21. V. 2015, collected by Yan Bin.

Etymology: The specific epithet is derived from the Latin word “ rostellatus ” meaning “beak” referring to the shape of the aedeagal shaft.

Remarks. This species is easily recognized by the lobe on the male subgenital plate and the long aedeagal processes surrounding the shaft.
