Head yellow. Frons yellow, about as long as wide and parallel–sided, with 2 brown stripes extending to ocellar triangle; ocellar triangle black; oc strong, almost as long as anterior or, anterior or inclinate, posterior or longer than 1/2 of anterior or. Face white to yellow, with a pair of shining brown stripe–like spots between stomatic margin and parafacial; gena about 1/11 height of eye. Antenna yellow except 1st flagellomere blackish brown on ventral 1/2–2/3; 1st flagellomere nearly 2.0 times longer than high; arista blackish brown, long plumose, with longest hairs 2.0 times longer than height of 1st flagellomere. Proboscis yellow except blackish brown on apical margin, with yellow and slightly dark hairs; palpus blackish brown except yellow on basal 1/3, with dark hairs.

Hind tibia with 1 weak preapical ad and 1 short apv. Wing ( Fig. 1 ) with a hyaline costal stripe extending to M1+2, but not confluent with a short hyaline stripe on hind margin; a semicircular hyaline apical stripe between R2+3 and M3+4 and a hyaline round spot beyond r-m; a tinged brown spoon–like spot on r-m and a tinged brown triangular stripe over m-m; subcostal cell tinged brown; costa with 2nd (between R1 and R2+3), 3rd (between R2+3 and R4+5) and 4th (between R4+5 and M1+2) sections in proportion of 2.0 mm: 0.5 mm: 0.4 mm; r-m beyond 3/4 of discal cell; ultimate and penultimate sections of M1+ 2 in proportion of 1.5 mm: 0.9 mm; ultimate section of CuA1 about 1/4 of penultimate. Halter pale yellow, knob blackish brown except tinged yellow at tip.

Abdomen shining brownish black except pale brownish yellow on protandrium and epandrium, with sparse grayish white pollen. Male genitalia ( Figs. 3–7 ): protandrium slender, circular with a ventral bridge; epandrium nearly rhombic; surstylus narrow, consisting of a short awl–shaped process and a long curved awl–shaped process with long hairs; hypandrium nearly W–shaped, gonopod with two acuate furcated apical processes with a long hair in ventral view; aedeagus with two claviform basal processes and with a pair of coniform apical processes in ventral view; aedeagal apodeme Y–shaped, nearly 1.1 times longer than aedeagus.

Type material. Holotype male, Hainan: Jianfengling National Nature Reserve, Hongmao village (430 m), 22. V. 2007, Junhua Zhang. Paratypes: 2 males, Hainan: Wuzhishan National Nature Reserve, Guanshantai (600 m), 29. X. 2007, Xingyue Liu; 1 female, Hainan: Wuzhishan National Nature Reserve, Dengshandao (800 m), 15. V. 2008, Qifei Liu; 1 male, Hainan: Jianfengling National Nature Reserve, Ledong, Sanfenqu (800 m), 8. V. 2008, Qifei Liu; 2 males, Hainan: Yinggeling National Nature Reverve, Hongmao village (430 m), 22. V. 2007, Kuiyan Zhang; 1 male, Hainan: Bawangling National Nature Reverve, Donger station (1000 m), 22. X. 2007, Xingyue Liu.

Distribution. China (Hainan).

Remarks. The new species is somewhat similar to Noonamyia euphlebia Sasakawa from Malaysia in the following characters: face with a pair of shining brown stripe–like spots between stomatic margin and parafacials; hind tibia with 1 preapical ad; abdomen shining brownish black except protandrium and epandrium pale brownish yellow. But it can be separated from the latter by the wing with a hyaline round spot beyond r-m and a tinged brown spoon–like spot on r-m, the surstylus consisting of a short awl–shaped process and a long curved awl–shaped process, the hypandrium nearly W–shaped, the gonopod with two furcated acuate apical processes. In euphlebia , the wing with a hyaline elliptic spot beyond r-m and a hyaline bar–like spot on r-m; the surstylus has a unique incurved triangular process; the hypandrium is U–shaped; the gonopod is acinaciform without basal tooth ( Sasakawa 1998).

Etymology. Latin, bi-, prefix meaning two + subulata, meaning awl-shaped and pointed, referring to the two awl-shaped processes on the surstylus; a feminine adjective.
