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 : 291-292

Genus Uniformus Jiao & Yang, 2020

Uniformus Jiao & Yang, 2020: 596

Type species: Uniformus rostellatus Jiao & Yang, 2020

Type locality: China (Yunnan)

Description. Body medium-sized, brightly colored with yellowish and orange stripes and patches ( Figs 1 , 16 ). Face depressed in lateral view with frontoclypeal area slightly concave ( Figs 4 , 19 ). Crown convex with length along midline shorter than distance between eyes, coronal suture distinct and short ( Figs 3 , 18 ). Forewing with 4th apical cell not reaching apex ( Figs 8 , 23 ); hindwing transparent with anal vein branched ( Figs 7 , 22 ).

Abdominal apodemes reaching 4th or 5th abdominal sternite ( Figs 12 , 26 ). Pygofer side broad basally with lateral side narrowed and prolonged, row of rigid microsetae along caudal margin ( Figs 10 , 25 ). Subgenital plate broad basally and curved dorsad distally, rows of macrosetae and rigid microsetae laterally ( Figs 9–10 , 24–25 ). Paramere slender and straight with apex slightly to strongly curved ( Figs 15 , 30 ). Connective lamellate with central ridge absent ( Figs 11 , 26 ). Aedeagus structurally complex; dorsal apodeme developed; preatrium large with large posteriorly directed process bearing one or more pairs of posterolateral branches bent dorsad; aedeagal shaft tubular, with dense microsetae terminally; gonopore apical ( Figs 13–14 , 28–29 ).

Remarks. Uniformus is very similar to Naratettix Matsumura in having the aedeagus with a posterior preatrial process, but Uniformus differs in having the processes of the preatrium bent dorsad distally (bent ventrad in Naratettix ), the paramere thin and long (broad and short in Naratettix ) and connective with central ridge absent (present in Naratettix ).
