Tautoneura baiyunshana Song, Li & Xiong sp. n. Figures 1-9

Description.

Body brownish yellow or brown testaceous. Head (Fig. 1) narrower than pronotum. Crown (Fig. 1) anteriorly produced medially, coronal suture distinct. Vertex (Fig. 1) median length little shorter than width between two eyes. Vertex and pronotum (Fig. 1) with milky yellow stripes. Eyes (Fig. 1) brownish yellow. Scutellum (Fig. 1) brownish yellow, basal triangles darker. Forewing (Fig. 2) brownish yellow, semitransparent, with four irregular dark spots and with two broad orange red patches near claval suture.

Abdominal apodemes (Fig. 3) small, not exceeding hind margin of 3rd sternite.

Pygofer (Fig. 4) broad, with three macrosetae at baso-lateral angle and a few sparse long fine setae. Pygofer microtrichia conspicuous, well developed. Pygofer dorsal appendage simple, not extended beyond pygofer apex, curved ventrally. Anal tube appendage (Fig. 4) hook-like apically. Subgenital plate (Fig. 5) lateral margin distinctly widened subbasally, with four macrosetae near median and with several short rigid setae along upper margin of sub-basal part. Style (Fig. 6) apex expanded, preapical lobe prominent. Connective (Fig. 9) nearly Y-shaped, central lobe and lateral arms slender; stem well developed, compressed. Aedeagal shaft (Fig. 7) almost straight, with pair of long processes arising near apex, another pair of short processes at middle area of shaft, triangular, lamellate in lateral view. Gonopore (Figs 7, 8) subapical and on ventral margin. Dorsal apodeme (Fig. 7) short; preatrium (Figs 7, 8) long and slim, about as long as or little longer than shaft.

Measurement.

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

Host Plant.

Unknown.

Type material.

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.

Remarks.

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.

Etymology.

The new species is named after its type locality: “Baiyunshan”, Henan Province.
