description: Phobeticomyia uncinata sp. nov.
(Figs. 7–8, 12, 28–32)
Diagnosis. Antenna yellow except scape and pedicel black, 1st flagellomere brownish yellow on apical 1/2. Wing with a hyaline stripe at extreme tip; two hyaline spots between R2+3 and R4+5; a large hyaline spot basal to r-m and a T–shaped hyaline spot below r-m in discal cell; a hyaline round anterior spot on dm-cu, separated from apical hyaline spot on ultimate section of CuA1; a hyaline subapical stripe in m1 cell and an undulating hyaline stripe along hind margin of cua1 cell.
Description. MALE. Body length 4.1 mm, wing length 4.0 mm.
Head (Figs. 7–8) brownish yellow. Frons yellow, wider than long and parallel–sided, with two velvety black stripes extending to ocellar triangle, basally confluentwith a W–shaped black transverse band. Ocellar triangle black; oc absent; anterior or inclinate, shorter than posterior one. Face shining, blackish brown on dorsal 1/2 and yellow with a pair of brown trapeziform spots on ventral 1/4. Parafacia black on dorsal 1/2, and yellow on ventral 1/2 with silvery white pollen. Gena pale brown with silvery white pollen along eye margin, about 1/3 height of eye. Antenna yellow except scape and pedicel black, 1st flagellomere brownish yellow on apical 1/2, nearly 1.7 times longer than high; arista long plumose, black, with longest hairs longer than width of 1st flagellomere. A silver white spot present between antenna and eye. Proboscis brown with yellow and blackish hairs; palpus black, with black hairs.
Thorax brown with grayish white pollen. Mesoscutum with a thin grayish white stripe between two wide brown median stripes and two brown lateral stripes behind suture, and a thin grayish white stripe along dc rows; 0+3 dc, with a brownish spot on base of each dc; acr in 10 rows; prsc shorter than 1st post–sutural dc. Mesopleuron brown, with a wide grayish white median stripe; 1 anepst, 2 kepst. Scutellum brown with yellowish brown pollen. Legs blackish brown, except all tarsi pale yellow and hind tibia pale brown; all tibiae with a pale yellow subapical ring. Fore femur with 5 pv and 8 pd, ctenidium with 13 short bristles; fore tibia with 1 preapical ad and 1 short apv. Mid femur with 5 a; mid tibia with 1 preapical ad and 3 strong apv. Hind femur with 1 weak preapical ad and a row of av (only 5 apical bristes distinct); hind tibia with 1 weak preapical ad and 1 short apv. Wing (Fig. 12) brown, a hyaline stripe at extreme tip; two hyaline spots between R2+3 and R4+5; a large hyaline spot basal to r-m and a T–shaped hyaline spot below r-m in discal cell; a hyaline round anterior spot on dm-cu, separated from apical hyaline spot on ultimate section of CuA1; a hyaline subapical stripe in m1 cell and an undulating hyaline stripe along hind margin of cua1 cell; subcostal cell with a hyaline spot; 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 2.0 mm: 0.6 mm: 0.4 mm; r-m nearly at middle of discal cell; ultimate and penultimate sections of M 1 in proportion of 1.2 mm: 1.8 mm; ultimate section of CuA1 about 1/9 of penultimate. Halter yellow.
Abdomen black with sparse grayish white pollen. Male genitalia (Figs. 28–32): protandrium circular with a median incision; epandrium broad with dense hairs on dorsoapical corner; surstylus with a slender subuliform subapical process and a special forcipiform inner process in lateral view; hypandrium nearly H–shaped, gonopod very narrow and hook–shaped; aedeagus with a pair of triangular basal processes, a pair of acuate dorsal and lateral processes, and a hooked apical process in lateral view.
FEMALE. Unknown.
Type material. Holotype male, Yunnan: Mengyang, Yexianggu (760 m), 17. IV. 2007, Wenliang Li.
Distribution. China (Yunnan).
Remarks. The new species is somewhat similar to Phobeticomyia bicolor Sasakawa & Pong from Malaysia (Sabah) in the wing pattern with two hyaline spots between R2+3 and R4+5, a hyaline subapical stripe in m1 cell, a hyaline spot on dm-cu and ultimate section of CuA1. But it can be separated from the latter by the following characters: the epandrium round apically without process; the surstylus with a slender subuliform subapical process and a forcipiform inner process; the aedeagus consisting of a pair of slender sclerites, a pair of triangular basal processes, a pair of acuate dorsal and lateral processes, and a hooked apical process; the aedeagal apodeme longer than 1/2 of the aedeagus. In bicolor, the epandrium has a small blunt apical process; the surstylus has a long curved inner process; the aedeagus is consisting of a pair of slender coniform sclerites without process; the aedeagal apodeme is shorter than 1/2 of the aedeagus (Sasakawa & Pong, 1990).
Etymology. Latin, ‘ uncinata ’ = hook-shaped, referring to the aedeagus with a hooked apical process; a feminine adjective.
