Epandrium with a pair of short black conical dorsoapical processes in lateral view; surstylus bluntly rounded, not incurved distally; basal phallus blunt and not recurved; distiphallus with distal processes broader, and lacking processes extending out near rounded postgonite. Description. MALE. Body length 3.9 mm, wing length 3.5 mm. FEMALE. Body length 3.9–4.1 mm, wing length 3.5–3.7 mm. Head yellow. Frons with a blackish brown median stripe in a broad dark rectangular area extending from anterior margin to ocellar triangle and with short setulae on anterior 1 / 2, about 1.6 times longer than wide and parallel-sided; ocellar triangle grayish black; ocellar setae very small, hair-like; anterior fronto-orbital (situating at middle of fronto-orbital plate) reclinate, shorter than the posterior. Facial keel distinct on upper 1 / 2 between bases of antennae; parafacial with sparse short setulae and six black short setae between parafacial ventral corner and gena; gena with brown stripe, about 1 / 3 height of eye. Antenna yellow, 1 st flagellomere rounded apically, about 1.4 times longer than high; arista brown, pubescent. A black velvety round spot present between eye and base of antenna. Proboscis mostly yellow except pale brown tip; palpus yellow. Thorax brownish yellow, with grayish white pruinosity. Mesonotum with four wide brown stripes, two brown median stripes extending to tip of scutellum; 0+ 3 dorsocentral setae, acrostichal setulae in 2 rows; prescutellar setae shorter than 1 st post-sutural dorsocentral setae; anepisternum yellowish brown and katepisternum blackish brown with grayish white pruinosity; 1 anepisternal seta, 1 katepisternal seta. Scutellum yellow, with grayish white pruinosity and a pair of wide brown stripes. Legs mostly yellow, fore tarsomeres 2–5 blackish brown, mid and hind tarsomeres 4–5 brown. Fore femur with 4 posteroventral setae and 8 posterodorsal setae, fore tibia with 1 preapical anterodorsal seta and 1 short apicoventral seta. Mid tibia with 1 strong preapical anterodorsal seta and 1 strong apicoventral seta. Hind femur with 1 weak preapical anterodorsal seta and 1 long anteroventral seta; hind tibia with 1 preapical anterodorsal seta and 1 short apicoventral seta. Wing (Fig. 10) brown along costal margin extending to M 1, a weak brown spot each on crossveins r-m and dm-cu; subcostal cell brown; costa with 2 nd (between R 1 and R 2 + 3), 3 rd (between R 2 + 3 and R 4 + 5) and 4 th (between R 4 + 5 and M 1) sections in proportion of 6.3: 1: 1.3; crossvein r-m at middle of discal cell; ultimate and penultimate sections of M 1 in proportion of 1: 1.3; ultimate section of CuA 1 about 1 / 7 of penultimate. Halter yellow. Abdomen yellow, male tergites 1–6 (female 1–7) each with black posterior margin. Male genitalia (Figs 11– 15): epandrium with a pair of short black conical dorsoapical processes in lateral view; surstylus bluntly rounded, not incurved distally, with dense apical setae; hypandrium broad with a pair of lateral concavities; postgonite elliptical; basal phallus blunt and not recurved; distiphallus with distal processes broader, and lacking processes extending out near rounded postgonite; phallapodeme very slender in ventral view and broad claviform in lateral view. Ejaculatory apodeme short and straight. Type material. Holotype male (CAUC), Yunnan: Xishuangbanna, Mengla, Menglun plant garden, 570 m, 22. IV. 2007, Hui Dong. Paratypes: 1 female (CAUC), Yunnan: data same as above; 1 female (CAUC), Yunnan: Xishuangbanna, Mengyang, 1100–1300 m, 28. X. 1998, Wanzhi Cai. Distribution. China (Yunnan). Remarks. The new species is very similar to Luzonomyza gaimarii sp. nov. from China (Yunnan) in the following characters: frons with a blackish brown median line in a broad dark rectangular area extending from anterior margin to ocellar triangle; parafacial with six black short setae between parafacial ventral corner and gena; antenna yellow and arista brown; palpus yellow; mesonotum with four wide brown stripes, two brown median stripes extending to tip of scutellum; legs mostly yellow, except fore tarsomeres 2–5 blackish brown and mid and hind tarsomeres 4–5 brown; wing brown along costal margin extending to M 1, a brown spot each on r-m and dmcu; abdomen yellow, male tergites 1–6 each with a black posterior margin. But it can be separated from the latter by the hind femur having 1 long anterovental seta; the epandrium having a pair of short black conical dorsoapical processes in lateral view; the surstylus being bluntly rounded and not incurved distally; the phallus having a pair of broad apical processes. In Luzonomyza gaimarii sp. nov., the hind femur has no long anterovental seta; the epandrium has a pair of long black conical dorsoapical processes in lateral view; the surstylus is tapering and incurved; the phallus has a pair of thin apical processes and a pair of subapical thin processes extended out near postgonite. Etymology. Latin, hirsuta, meaning hairy, referring to the surstylus having dense apical setae; a feminine adjective.Published as part of Shi, Li & Yang, Ding, 2015, Two new species of the genus Luzonomyza from CHINA (Diptera, Lauxaniidae), pp. 87-94 in Zootaxa 3964 (1) on pages 91-94, DOI: 10.11646/zootaxa.3964.1.5, http://zenodo.org/record/28870
