( Figs 1–7 View FIGURES 1 – 3 View FIGURES 4 – 7 )
Diagnosis. Palpus yellow. Fore tarsomeres 2–5 blackish brown, mid and hind tarsomeres 4–5 brown, hind femur without long anteroventral seta. Halter yellow except knob pale brown. Epandrium with a pair of long black conical dorsoapical processes in lateral view; surstylus tapering distally and incurved; basal phallus recurved and extended posteriorly to pointed tip; distiphallus with a pair of thin processes distally, and a pair of thin processes extending out from rounded postgonite.
Description. MALE. Body length 4.1–4.3 mm, wing length 3.9–4.0 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; nearly 1.4 times longer than wide and parallel-sided; ocellar triangle grayish black; ocellar setulae very small, hair-like; anterior fronto-orbital seta (situated 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 wide brown stripe, about 1/3 height of eye. Antenna yellow, 1st flagellomere rounded apically, about 1.5 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 1st post-sutural dorsocentral setae; anepisternum yellowish brown except lemon yellow on upper margin 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, 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; hind tibia with 1 preapical anterodorsal seta and 1 short apicoventral seta. Wing ( Fig. 3 View FIGURES 1 – 3 ) brown along costal margin extending to M1, a brown spot each on crossveins r-m and dm-cu; subcostal cell brown; costa with 2nd (between R1 and R2+3), 3rd (between R2+3 and R4+5) and 4th (between R4+5 and M1) sections in proportion of 7.7: 1:1; r-m at middle of discal cell; ultimate and penultimate sections of M 1 in proportion of 1: 1.3; ultimate section of CuA1 about 1/8 of penultimate. Halter yellow except knob pale brown.
Abdomen yellow, male tergites 1–6 each with black posterior margin. Male genitalia ( Figs 4–7 View FIGURES 4 – 7 ): epandrium with a pair of long black conical dorsoapical processes in lateral view; surstylus tapering distally and incurved, with dense long setae; hypandrium broad with a pair of lateral concavities, narrow apically; postgonite semicircular; basal phallus recurved and extended posteriorly to pointed tip; distiphallus with a pair of thin processes distally, and a pair of thin processes extending out from rounded postgonite; phallapodeme slender claviform in ventral view and broad knife-like in lateral view. Ejaculatory apodeme bent.
FEMALE. Unknown.
Type material. Holotype male ( CAUC), Yunnan: Menglun, No. 55 area, 920 m, 24. IV. 2007, Hui Dong. Paratype ( CAUC): 1 male, Yunnan: data same as above.
Distribution. China (Yunnan).
Remarks. The new species is similar to Luzonomyza sinica Shatalkin, 1998 from Thailand and China in the following characters: wing with brown along costal margin extending to M1, a brown spot each on r-m and dm-cu. But it can be separated from the latter by the surstylus tapering and being incurved with dense long setae. In L. sinica Shatalkin , the surstylus forms a dorsoapically directed process without setae in posteror view.
Etymology. The new species is named after the dipterist Stephen D. Gaimari who makes great contributions to Entomological research and gives the author Li Shi so much kind help and support.
