Treatment

Leucophenga apunctata Huang & Chen , sp. nov.

( Figs 2 View FIGURE 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 View FIGURE 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 View FIGURE 4 I), sometimes without any stripes in some paratypes. Postpronotal lobe yellowish brown. Acrostichal setulae in ca. 14 irregular rows ( Fig. 4 View FIGURE 4 I). Scutellum yellowish brown, pale at tip ( Fig. 4 View FIGURE 4 I). Katepisternum brownish yellow ( Fig. 4 View FIGURE 4 J). Meron slightly brown ( Fig. 4 View FIGURE 4 J). Wing ( Fig. 2 View FIGURE 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 View FIGURE 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 View FIGURE 18 A). Hypandrium with 1 long sensillum ( Fig. 18 View FIGURE 18 B). Paramere distally broadened, with 4 sensilla and pubescence ( Fig. 18 View FIGURE 18 C). Aedeagus not reticulated, distally ventrad curved and with a small, dorsal projection ( Fig. 18 View FIGURE 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).
