Material examined.

Holotype, ♀: 'Wushe. Taiwan 1150m. V-15-83 Henry Townes’ (EMUS). Paratypes: 1♂, ' TAIWAN: Kaohsiung, Luluei Forest Sta., 750m; May 1 1989; J. Heppner & W. Wang’ (EMUS) .

Diagnosis.

Both sexes: clypeus narrower than LID (Figs 3A, 4A); mid and hind femora without small spines set in pits apicodorsally. Female: thorax almost black (Fig. 3G); gena, in dorsal view, slightly thickened, roundly receding posteriorly (Fig. 3B); and lateral margin of pronotal dorsum, in dorsal view, concave, not narrowing anteriorly (Fig. 3B). Male: thorax dark rufous (Fig. 4I); frons, in profile, spherically convex (Fig. 4I); placoids small, shorter than half of each flagellomere (Fig. 4E); SGP triangular with rounded apex (Fig. 4F); and inner margin of parapenial lobe finely and irregularly serrate (Fig. 4G, H).

Description.

Holotype female. Length: Body 6.0 mm; forewing 5.9 mm. Body and legs black (Fig. 3D). Following dark rufous: palpi, clypeus, labrum, mandible, flagellum beneath, legs, and metasoma. Scape and pedicel beneath light brown (Fig. 3A). Wings translucent with brownish tint (Fig. 3F). Pubescence on pronotum posteriorly and mesonotum sericeous.

Head 1.4 × as broad as long. Vertex, in frontal view, almost transversely straight but slightly raised in ocellar area (Fig. 3A). Frons in lateral view strongly convex, but upper frons and vertex flattened (Fig. 3G), with frontal line very fine from antennal base to anterior ocellus. Antennocular line distinctly inclined from antennal base toward eye (Fig. 3B). MID 0.61 × head width. UID:MID:LID = 8.1:10:7.5. POL:OOL = 1:0.86. Clypeus 2.3 × as broad as long; apical margin barely and arcuately emarginate. Gena, in profile, thin, 0.2 × eye width (Fig. 3G). Scape:Fl1:Fl2 = 7.2:10:8.7; Fl1 4.2 × as long as thick, 0.78 × as long as UID.

Pronotum gently and arcuately emarginate posteriorly (Fig. 3B). Mesoscutum scarcely raised posterolaterally. Disc of scutellum not convex above level of mesoscutum. Metapostnotum 0.1 × as long as metanotum and depressed medially, with a few fine transverse striae (Fig. 3C).

Mid tibia with four spines externally and one spine internally; hind tibia with five or six spines externally and five spines internally (Fig. 3H). Longer spur of hind tibia 0.63 × hind tarsomere 1.

FW and HW as shown in Fig. 3F. Marginal cell removed from wing tip by 0.46 × its own length. SMC2:SMC3 = 1:1.3 on vein M, 1:0.48 on vein Rs. SMC2 narrowed on vein Rs by 0.82 × its length on vein M, receiving crossvein 1m-cu at basal 0.5. SMC3 narrowed on vein Rs by 0.3 × its length on vein M, receiving crossvein 2m-cu at basal 0.54, removed from outer wing margin by 1.8 × its own length. Crossvein cu-a originating slightly distal to point of separation of vein M+CuA, leaning toward wing base. HW jugal lobe less than third of subbasal cell in length.

Male. Based on the only paratype. Body 3.8 mm; forewing 3.6 mm. Body and legs reddish brown (Fig. 4C); scape and pedicel yellowish brown beneath.

Head 1.3 × as broad as long. Vertex distinctly convex between eye tops (Fig. 4A). Antennocular line strongly inclined from antennal base toward eye (Fig. 4B). MID 0.67 × head width. UID:MID:LID = 8.6:10:7.3. POL:OOL = 1:0.87. Clypeus much narrower than LID (Fig. 4A), 2.3 × as broad as long; surface more convex than in female; apical margin transversely straight. Gena, in profile, 0.3 × eye width. Scape:Fl1:Fl2 = 8.4:10:10; Fl1 2.4 × as long as thick, 0.54 × as long as UID.

Metapostnotum very short, 0.06 × as long as metanotum at midline.

FW and HW as shown in Fig. 4D. Marginal cell removed from wing tip by 0.38 × its own length. SMC2:SMC3 = 1:2 on vein M, 1:0.67 on vein Rs. SMC2 not narrowed above, receiving crossvein 1m-cu at basal 0.43. SMC3 narrowed on vein Rs by 0.34 × its length on vein M, receiving crossvein 2m-cu at basal 0.51, removed from outer wing margin by 1.5 × its own length. Crossvein cu-a perpendicular to vein A.

Mid tibia with very small spines dorsally, three spines externally and two spines internally. Hind tibia with spines longer than those on mid tibia, five or six spines externally and three or four spines internally. Longer spur of hind tibia 0.65 × hind tarsomere 1.

SGP somewhat concave beneath. Genitalia (Fig. 4G, H): volsella slender but broadened apically with rounded apex and several long setae; parapenial lobe extending far beyond apex of volsella; aedoeagus parallel-sided for most part.

Etymology.

The species name is derived from its locality, i.e., Taiwan.
