Huang, Min, Kang, Juxia & Zhang, Yalin, 2018, First record and new species of the Oriental leafhopper genus Trifida Thapa & Sohi (Hemiptera: Cicadellidae: Typhlocybinae) from China, Zootaxa 4420 (4), pp. 593-599 : 597

Trifida robusta Huang, Kang et Zhang , sp. nov.

( Figures 3, 7, 11, 15 , 28–34 )

Measurement. Male, 3.5–3.7mm (including wings).

Dorsum light yellowish-white with two brownish-yellow bands extending from anterior margin of vertex to end of pronotum ( Fig.11 ); face brownish-yellow ( Fig.15 ).

Abdominal apodemes reaching 5th abdominal sternite. Pygofer side with process simple ( Fig.31 ). Paramere with subapical protrusion rounded ( Fig.30 ). Connective short and broad with apical feet slender ( Fig.29 ). Process of dorsal apodeme of aedeagus with apical half recurved in lateral view and apex broadened and Y-shaped in posterior view; aedeagal shafts broadened in lateral view with two adjacent tooth-like protrusions near midlength and directed ventrad ( Figs 28–29 ).

Observed Materials. Holotype: ♂, CHINA, Yunnan Province, Mt. Tianbao, Dongaotou , 1700m, 20–XI– 1999, coll. Irena DWORAKOWSKA. Paratypes : 1 ♂ 3 ♀♀, same data as holotype .

Notes. The new species is similar to Trifida melichari (Distant, 1908) in color pattern and male genitalia, but can be distinguished from the later by the aedeagus with two adjacent protrusions at midlength of shaft and the dorsal apodeme narrower preapically.

Etymology. The specific epithet is derived from the Latin word “ robustus ” which means “robust”, referring to its robust apical part of the dorsal apodeme process of the aedeagus.
