description: Leucophenga apunctata Huang & Chen, sp. nov.
(Figs 2 E, 4I, 4J, 8E, 10I, 10J, 18)
Diagnosis. This species is very similar to L. hirsutina sp. nov. in the wing lacking distinct patches and the katepisternum brownish yellow (Figs 2 E, 4J, 3C, 6F), see under that species.
Description. Ocellar triangle dark brown, with ca. 3–5 setae above ocellar setae. Frons yellowish brown to dark brown. Pedicel yellow, first flagellomere yellowish brown. Clypeus brown. Mesonotum yellowish brown, with 3 diffuse, dark longitudinal stripes: broad medially and thin laterally in holotype (Fig. 4 I), sometimes without any stripes in some paratypes. Postpronotal lobe yellowish brown. Acrostichal setulae in ca. 14 irregular rows (Fig. 4 I). Scutellum yellowish brown, pale at tip (Fig. 4 I). Katepisternum brownish yellow (Fig. 4 J). Meron slightly brown (Fig. 4 J). Wing (Fig. 2 E): Costal vein between R2+3 and R4+5 distally with ca. 7–10 peg-like spinules on ventral surface. Abdominal tergites brownish to brown (Fig. 8 E); second yellow medially; third with a pair of yellow patches submedially along margin; fourth and fifth entirely brown; sixth with yellow on posterior margin. Male terminalia: Epandrium with ca. 19 setae near dorsal to ventral margins per side (Fig. 18 A). Hypandrium with 1 long sensillum (Fig. 18 B). Paramere distally broadened, with 4 sensilla and pubescence (Fig. 18 C). Aedeagus not reticulated, distally ventrad curved and with a small, dorsal projection (Fig. 18 D).

Type specimens. Holotype ♂ (SCAU, No. 121563), CHINA: Maoniuhe, Danba, Sichuan, alt. 2650m, 14.ix.2005, ex tree trunk, HW Chen. Paratypes: CHINA: 12♂, 5♀ (2♂, 2♀ in KIZ; 10♂, 3♀ in SCAU, Nos 121564 –76), same data as holotype, HL Cao, HW Chen, MF Xu.
Etymology. A combination of the Latin words “ a- ” (= absent) + “ punctatus ” (= patch), referring to the wing without distinct patches.
Distribution. China (Sichuan).
