Paratype
: male, same data as holotype.
Male: Body length 4.0 mm.
Head: Eyes bare, lower posterior margin slightly concave. Frons about 0.34 times as wide as head, lateral margins parallel. Frontal vitta black in ground colour, with faint gray pruinosity. Frontal triangle with faint gray pruinosity, reaching anterior margin of frons. Ocellar longer than frons width. Outer vertical seta about 1.5 times as long as posterior vertical, about 2/3 of ocellar. Fronto-orbital with faint gray pruinosity. Distance between orbital setae about 1.5 times as long as that between frontal setae. Profrons not projecting. Face dark, with faint gray pruinosity, parafacial and facial ridge with dark yellow pruinosity. Parafacial about 1/3 of flagellum 1 width. Gena dark, about 1/12 of eye height. Occiput dark, with gray pruinosity. Antenna brown-yellow, basal half red-yellow. Flagellum 1 about twice as long as pedicel. Distance between end of antenna and epistoma about 1/2 of flagellum 1 length. Arista short ciliated in basal 1/3, the longest hair about 1/2 of flagellum 1 width, arista bare in apical 2/3. Palpi red-yellow, prementum dark brown.
Figs 53–58.

Wings: Hyaline, veins yellow. Costal spine well marked. Calypters yellow to white. Lower calypter about 1.5 times as long as upper. Halters yellow.
Legs: Coxa, fore femur, mid femur and apical 1/3 of hind femur dark brown, remaining yellow. Mid femur with 1 row of

Abdomen: Columniform, longer than thorax, syntergite 1+2 and posterior margin of tergite 3 yellow, remaining dark brown, with gray pruinosity. Abdominal tergites 3–4 with faint median vittae respectively, tergite 3 with faint lateral spots, tergites 4–5 each with 1 pair of black rounded lateral spots, spot width about 1/2 of tergite length respectively. Tergite 5 with developed discal and posterior marginal setae, tergite 8 with 3 discal setae. Sternites with long hairs, densest and longest on sternite 5. Lateral lobes of sternite 5 yellow, with apical long setae (
Fig. 58
). Apical half of surstyli curving inward.
Female: Unknown.
Etymology: The specific name refers to male apical half of surstyli curving inward (
Fig. 54
).
Curvus
means curving and
lobatus
means lobed in Latin.
Remarks: Resembles
L. orbiprotuberans
(
XUE
&
YANG
, 1998), but can be recognised by male fore coxa brown, fore femora dark brown; abdominal syntergite 1+2 without lateral spots; abdominal tergite 5 with 1 pair of black rounded lateral spots.
