(Figs. 1–11)
Diagnosis. Body brown. Mesonotum entirely brown. Mid tibia shorter than fore tibia. Cercus rather large, nearly as long as epandrium, bilobed apically.
Description. MALE. Body length 2.8 mm, wing length 2.7–2.8 mm.
Head brown, covered with pale pruinosity; face and gena pale yellowish brown. Vestiture on head dark brown. Antennae dark brown; arista long, black. Proboscis and palpus brown.
Thorax brown with pale pruinosity; scutellum with yellowish brown margin. All setae dark brown. Legs (Figs. 1–4) brownish yellow, with black vestiture. Mid tibia shorter than fore tibia. Fore femur apically with 2 ad, 1 d, 1 pd, 1 av and 1 pv; fore tibia with 1 short d at base, 1 ad and 1 pd at middle, apically with 1 short d, 1 pv and 1 pd. Fore tarsomere 3 with 7 small ventral spines; tarsomere 5 with 6 short setae. Mid femur with 1 ad at basal 2/5, apically with 1 a, 1 d, 1 av and 1 pv; mid tibia with 1 short d at base, 1 ad and 1 pd at middle, apically with 1 preapical ad, 1 preapical av, 1 d, 1 short av and 1 pv. Hind femur apically with 2 ad, 1 av, 1 d, 1 pv and 1 pd; hind tibia basally with 1 short d, 1 ad and 1 pd at middle, apically with 1 preapical ad, 2 short preapical av and 1 d. Hind tarsomere 1 with 1 slightly long av and 1 pv at extreme base, apically with 1 av and 1 pv. Wing pale yellowish brown; veins brown, with dorsal setulae except Sc and R2+3; a row of longer setulae at base of C. Relative lengths of M1+2:M2 = 42:67. Halter brown with yellowish brown stem.
Abdomen dark brown, covered with pale pruinosity, but brownish ventrally. Vestiture on abdomen black. Sternite 3 (Fig. 5) with a large semicircular mid-posterior incision. Tergite 8 small, triangular. Male genitalia (Figs. 6–11): Epandrium longer than broad, with dense long lateral setulae posteriorly. Cercus rather large, nearly as long as epandrium, bilobed apically, with two rows of short setulae on basal 1/2 at middle, and with long lateral setulae and very long apical setulae (longest setulae nearly as long as cercus). Aedeagus long and thick basally, shallowly incised apically. Gonopod weakly incised posteriorly, with 2 short spines at posterolateral corner. Paramere short and thick, with 2 outer setulae at middle.
FEMALE. Unknown.
Type material. Holotype male, Guangxi: Shangsi, Pinglongshan, 1. IX. 2006, Yinxia Liao. Paratype 1 male, same locality as holotype, 22. V. 2006, Yinxia Liao.
Distribution. Known only from the type locality in Guangxi.
Etymology. The species is named after the type locality in Pinglongshan.
Remarks. The new species is somewhat similar to L. nigrociliata Duda from Poland, but it can be separated from the latter by the male cercus rather long, nearly as long as the epandrium. In L. nigrociliata, the male cercus is rather short, about 1/2 as long as the epandrium (Smith, 1969).
