In the present paper, three new species are added to the genus Tautoneura Anufriev from China, Tautoneura baiyunshana sp. n., Tautoneura caoi sp. n. and Tautoneura yunnanensis sp. n. A key to species recorded from China is provided.

The leafhopper genus Tautoneura
The specimens were obtained by sweep net method and were
studied under Olympus SZX7 and CX41 microscopes. Morphological
techniques and terminology follow
Tautoneura tricolor Anufriev, 1969
Body small, about 2.0–3.0 mm, usually yellow or light yellow. Head bluntly produced medially, slightly narrower than pronotum or equal to greatest width of pronotum. Median length of vertex equal to or longer than length between eyes. Some species with more rounded anterior margin of vertex. Pronotum broad, often with irregular patches or spots; scutellum nearly triangular. Forewings usually with red markings or spots.
Pygofer lobe broad, usually with several macrosetae at basal lower angle and some short stout setae in distal part of lobe on inner surface, peg-like. Dorsal appendage of pygofer long, tapering apically, movably articulated with pygofer lobe. Some species have ventral appendage. Aedeagus usually with large dorsal apodeme and one or two pairs of processes of variable length at apex of shaft. Style slender, with slim “neck” subapically, and prominent preapical lobe. Connective nearly M- or Y-shaped, central lobe well developed, as long as or little shorter than lateral arms. Shape of anal tube appendage diverse, but that of most species hook-like at apex.

Holotype, male, China: Henan Province, Mt. Baiyunshan, 1300~1400 m, 17 August 2008, coll. Can Li. Paratypes: two males, ten females, same data as holotype.
The new species is similar to Tautoneura longiprocessa Song & Li (2008), but can be distinguished from the latter by the paired long processes arising from subapex of shaft (Figs 7, 8); gonopore (Figs 7, 8) subapical; preatrium (Fig. 7) slim, longer than aedeagal shaft.
