Zhang, Xinmin, Zhang, Yalin & Wei, Cong, 2010, Review of the leafhopper genus Taperus Li & Wang (Hemiptera: Cicadellidae: Evacanthinae) from China, with description of three new species, Zootaxa 2721, pp. 39-46 : 40

Key to species of the genus Taperus Li & Wang based on male adults

1. Aedeagal shaft with angulate posterior process near base ( Figs 22, 27 ); footlike apical process of style with apex very long and slender, at least one third length of style ( Figs 24, 29 ) .......................................................................... 2

-. Aedeagal shaft without posterior process near base ( Figs 32, 37, 42 ); footlike apical process of style with apex short and robust, about one sixth length of style ( Figs 34, 39, 44 )........................................................................................ 4

2. Pygofer longer than wide, with apical half distinctly narrowed, triangular or attenuated apically in lateral view ( Figs 21, 26 ) ........................................................................................................................................................................... 3

-. Pygofer nearly circular in lateral view ......................................................................................... T. apicalis Li & Wang

3. Pygofer triangular in lateral view, dorsal margin with a row of long spine-like macrosetae ( Fig. 21 ) .......................... ........................................................................................................................................................ T. bannaensis sp. n.

-. Pygofer attenuated apically in lateral view, apex with short but thick macrosetae ( Fig. 26 ) .... T. fasciatus Li & Wang

4. Pygofer nearly quadrangular or very slightly narrowed apically, with apex truncate in lateral view ( Figs 31, 36 )..... 5

-. Pygofer distinctly narrowed apically with apex rounded in lateral view ( Fig. 41 ) ...................................................... 6

5. Pygofer broad at base, slightly narrowed posteriorly with apex somewhat truncate in lateral view ( Fig. 31 ); aedeagal shaft with posterior margin concave and with apex very long and slender in lateral view, extending distinctly beyond dorsal area of lamellate lateral process of aedeagus ( Fig. 32 ) ............................... T. flavifrons (Matsumura) comb. n.

-. Pygofer nearly quadrangular in lateral view ( Fig. 36 ); aedeagal shaft with posterior margin not concave and with apex short in lateral view ( Figs 37–38 ) ...................................................................................... T. quadragulatus sp. n.

6. Apex of aedeagus well developed, about half length of aedeagal shaft, with two spinelike processes on dorsal margin and one spinelike process on ventral margin ......................................................................... T. albivittatus Li & Wang

-. Apex of aedeagus relatively short, about one fifth of aedeagal shaft, without processes ( Figs 42– 43 )........................ ....................................................................................................................................................... T. luchunensis sp. n.
