Diagnosis. This species is similar to L. digmasoma in the male terminalia, but can be distinguished from the latter by having the abdominal 2nd tergite yellow, with black patches ( Fig. 11 View FIGURE 11 F–H); the aedeagus round apically ( Fig. 32 View FIGURE 32 D).

Description. Ocellar triangle yellowish brown to dark brown, with 2–4 setae above ocellar setae. Frons yellowish brown. Pedicel yellowish brown, brown at tip; first flagellomere yellow. Clypeus yellowish brown. Palpus brownish. Mesonotum brownish yellow to yellowish brown, dark brown before scutellum ( Fig. 8 View FIGURE 8 E). Postpronotal lobe yellow ( Fig. 8 View FIGURE 8 F). Acrostichal setulae in 12–16 irregular rows ( Fig. 8 View FIGURE 8 E). Scutellum dark brown, pale at tip ( Fig. 8 View FIGURE 8 E). Pleura with an unapparent, brownish, longitudinal stripe above ( Fig. 8 View FIGURE 8 F). Katepisternum mostly brownish yellow; mesopleuron mostly yellow, with a brown patch ( Fig. 8 View FIGURE 8 F). Wing ( Fig. 3 View FIGURE 3 F, G): Costal vein between R2+3 and R4+5 distally with 4–7 peg-like spinules on ventral surface. Halter slightly brownish apically ( Fig. 8 View FIGURE 8 E). Mid and hindlegs brown on knees. Abdominal tergites dark brown to black, with yellow patches ( Fig. 11 View FIGURE 11 F–H). Male terminalia: Epandrium with pubescence and 6 setae near posterior margin and ventral corner per side ( Fig. 32 View FIGURE 32 A). Paramere with serrations and 4 sensilla dorsally ( Fig. 32 View FIGURE 32 C).

Type specimens. Holotype ♂ ( SCAU, No. 123139), CHINA: Tongmai, Bomi, Xizang, 2000 m, 12.x.2010, ex tree trunk, L Wang. Paratypes: CHINA: 2♂, 3♀ ( SCAU, Nos 123140 –44), same data as holotype; 1♂ ( SCAU, No.

123145), Hesong, Menghai, Yunnan, 1900m, 9.iv.2011, ex tree trunk, YR Su; 1♀ ( SCAU, No. 123003), Yixiang, Puer, Yunnan, 13.v.2012, 1400 m, ex tussock, JJ Gao.

Distribution. China (Yunnan, Xizang).

Etymology. A combination of the Latin words: “ hirtus ” (= hirsute) + “ ceps ” (= head) referring to the aedeagus with dense pubescence.
