Dorsum light yellowish-white with two brownish-yellow bands extending from anterior margin of vertex to end of pronotum (Fig. 10); face brownish-yellow (Fig. 14). Abdominal apodemes reaching 5 th abdominal sternite. Pygofer side with process bilobed (Fig. 26). Paramere with subapical protrusion triangular broadened basally. Connective short and broad with apical feet distinct (Fig. 25). Process of dorsal apodeme of aedeagus straight with termination narrowed; aedeagal shafts broadened in lateral view with two tooth-like protrusions subapically and directed ventrad, adjacent to each other at base, medial protrusion shorter and narrower than lateral protrusion. (Figs 24 – 25) Observed Materials. Holotype: ♂, CHINA, Hunan Province, Chenzhou, Mt. Wuzhifeng, 15 – VIII – 1985, coll. Yalin ZHANG and Yonghui CHAI. Paratypes: 2 ♂♂ 3 ♀♀, same data as holotype; 1 ♂ 1 ♀, Hunan Province, Hengshan, 11 – VIII – 1985, coll. Yalin ZHANG and Yonghui CHAI. 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 the protrusions on the aedeagal shaft more distal and fewer in number, and by the narrower apical part of the dorsal apodeme.	en	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.

B070878E08145078FF0C0151C56FF8E7.taxon	etymology	Etymology. The specific epithet is derived from the Latin word “ elegantem ” which means “ elegant ”, referring to the apical part of the dorsal apodeme of the aedeagus.	en	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.

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 5 th 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).

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.	en	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.

Connective short and broad with apical feet slender (Fig. 36). Process of dorsal apodeme of aedeagus arched in lateral view with terminal hooks slender, Y-shaped in posterior view; aedeagal shafts broadened in lateral view with two widely separated tooth-like protrusions, one subapical and one at midlength, both directed ventrad (Figs 35 – 36).

The new species is similar to Trifida melichari (Distant, 1908) in color pattern and male genitalia, but can be distinguished from the later by aedeagus with two different length protrusions on middle length of shaft and with subapical part of process of dorsal apodeme slender.	en	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.
