Body yellowish. Structural characters as in Tautoneura baiyunshana sp. n. and Tautoneura yunnanensis sp. n. Vertex and pronotum (Fig. 19) with irregular orange red markings. Eyes grey. Scutellum (Fig. 19) basal triangles orange yellow and apex with dark spot. Forewing (Fig. 20) brownish yellow, semitransparent, with numerous orange yellow markings, some parts with red spots or streak, apex (apical cells) dark brown.

Abdominal apodemes (Fig. 21) broad, extended beyond posterior margin of 3rd sternite.

Pygofer lobe (Fig. 22) broad, with numerous macrosetae, long fine setae and rigid short setae. Pygofer microtrichia inconspicuous. Dorsal appendage bifurcate far from base, extended beyond pygofer apex. Subgenital plate (Fig. 23) with four basal macrosetae and distinct marginal subbasal rigid setae formed continuous row. Style (Fig. 24) slender, apex expended slightly; preapical lobe prominent. Connective (Fig. 27) Y-shaped, two arms strong, central lobe well developed. Aedeagal shaft (Figs 25, 26) short, with pair of lateral processes at sub-base, part between aedeagal shaft and preatrium expanded. Gonopore nearly median, on ventral margin. Dorsal apodeme little longer than that of other two new species. Preatrium long, much longer than aedeagal shaft.

Measurement.

Body length males 2.5~2.6 mm, females 2.7~2.8 mm.

Host plant.

Ulmus pumila L. (Elm)

Type material.

Holotype , male, China: Gansu Province, Zhenyuan County, 19 May 2010, coll. WEI CAO. Paratypes: seven males, ten females, same data as holotype.

Remarks.

The new species is distinguishable from Tautoneura ahmedi Dworakowska (1977) by the aedeagus preatrium strongly expended at terminal part; the dorsal appengage bifurcate apically and the gonopore near median area of aedeagal shaft.
