Tautoneura yunnanensis Song, Li & Xiong sp. n. Figures 10-18

Description.

Body brownish yellow. Crown (Fig. 10) fore margin strongly produced and angulate medially. Coronal suture (Fig. 10) long, milky, nearly extended to 4/5 middle length of vertex. Two slim curving milky stripes situated at sides of coronal suture symmetrically. Eyes (Fig. 10) grey testaceous. Pronotum (Fig. 10) with two small orange red spots medially and broad area around them brownish. Scutellum (Fig. 10) light brown, with orange yellow spot at apex; basal triangles orange yellow. Forewing (Fig. 11) with four orange markings around claval suture and several brownish or blackish brown spots.

Abdominal apodemes (Fig. 12) large, broad, reaching 5th sternite.

Pygofer lobe (Fig. 13) broad, with two macrosetae at basal lower angle and numerous fine setae or microsetae distributed on lateral surface. Pygofer microtrichia distinct. Pygofer dorsal appendage expanded at base and tapering towards apex, bent ventrally. Anal tube appendage (Fig. 13) slim, hook-like apically. Subgenital plate (Fig. 14) with three basal macrosetae, expanded subbasally and with several peg-like short setae. Style (Fig. 15) quite long, apex expanded obviously; preapical lobe large, prominent. Connective (Fig. 18) Y-shaped, lateral arms strong, central lobe and stem well developed. Aedeagal shaft (Figs 16, 17) almost straight and short in lateral view, its base conspicuously expanded in ventral view; without any process. Gonopore (Figs 16, 17) broad, apically. Aedeagus dorsal apodeme (Fig. 16) short and small; preatrium (Figs 16, 17) much longer than aedeagal shaft.

Measurement.

Body length males 2.2~2.3 mm.

Host plant.

Unknown.

Type material.

Holotype, male, China: Yunnan Province, Lijiang, 16 July 2010, coll. CAN LI. Paratypes: one male, same data as holotype; one male, China: Yunnan Province, Mengla County, 18 July 2008, coll. YUEHUA SONG.

Remarks.

The new species is similar to Tautoneura misrai Dworakowska (1977), but can be distinguished from the latter by the large and broad, apical gonopore; the aedeagus dorsal apodeme short, not expanded distinctly and the ventral appendage absent; the forewing with four orange patches near claval suture.

Etymology.

The new species is named after its type locality: “Yunnan”, China.
