Description.

Head and thorax yellowish brown; vertex with lateral margins with soft red tinge; eyes brownish grey; pronotum brownish with two longitudinal darker stripes; scutellum with basal triangles testaceous. Forewing (Fig. 3) reddish brown near base, dark red between 4th apical cell and brochosome-field and light brown around apex; 3rd apical cell with a blackish brown spot.

Coronal suture (Fig. 1) extending nearly to anterior margin of vertex. Forewing (Fig. 3) with 3rd apical cell not petiolate at base.

Abdominal apodemes (Fig. 4) slender, slightly extended beyond 4th sternite.

Pygofer lobe (Fig. 5) broad, with a large sclerotized process near dorsal margin and another process arising from about ventro-caudal margin; six long macrosetae distributed along caudal margin and numerous short microsetae scattered on lateral surface. Subgenital plate (Fig. 6) long, gradually tapered towards apex and curved apically, beak-like; with three long macrosetae along upper margin. Style (Fig. 7) elongate, slender throughout length with truncate base. Aedeagal shaft (Figs 8, 9) curved dorsad in lateral view with single small dorsal process subapically; gonopore large, apical on ventral surface with small tooth on each lateral margin; preatrium long, about as long as aedeagal shaft; dorsal apodeme narrow. Connective (Fig. 10) Y-shaped with very short stem and long strongly divergent lateral arms; central lobe absent.

Measurement.

Body length males 2.9~3.1 mm.

Type material.

Holotype, male, China: Yunnan Province, Menghai County, 23 July 2008, coll. YUE-HUA SONG. Paratypes: two males, same date as holotype.

Remarks.

The new species is similar to Zyginella tsauri Chiang, Hsu & Knight (1989), but the forewing has a large dark costal patch (Fig. 3) and the aedeagus has a single short dorsal process subapically and a small tooth on each lateral margin of the gonopore (Figs 8, 9).

Etymology.

The new species is named for its type locality: Menghai.
