( Figs. 1–10 ) Diagnosis. Palpus yellow except pale brown at tip. Mesoscutum: presutural dorsocentral seta before horizontal level of presutural acrostichal setulae. Scutellum shiny blackish brown, with grayish white pruinosity on basal 1/4. Fore femur with 5 strong posterior ventral setae and hind femur with 2 strong anterior ventral setae. Wing with 9 white radiating stripes along margin between tips of R 2+3 and CuA 1, irregular hyaline spots of different sizes in brown central area. Surstylus consisting of 1 anterior process and 1 posteroapical process in lateral view. Description. MALE. Body length 3.2–4.0 mm, wing length 4.2–5.3 mm . FEMALE. Body length 3.0 mm, wing length 5.1 mm . Head ( Fig. 1 ) mostly pale yellow. Face pale yellow, with brown V-shaped median spot, lateral and ventral margin brown, pale brown groove near ventral margin; parafacial pale yellow, with narrow brown median stripe on basal 1/2 and an elliptical brown ventroapical spot.

Gena about 1/5 height of eye. Occiput black, with grayish pruinosity. Antenna yellow, flagellomere 1 about 1.7 times longer than high; arista blackish brown, pubescent, with short setulae. Short-horizontal brown stripe spot present between eye and antenna. Proboscis pale brownish yellow except white at tip, with yellowish and blackish setulae; palpus yellow except pale brown at tip, with black setulae. Thorax ( Fig. 4 ) brown, with grayish yellow pruinosity. Mesoscutum with pair of narrow brown median stripes extending from anterior margin to presutural acrostichal setulae, posterior margin of postpronotum surrounded by brown line, 3–4 brown spots scattered between dorsocentral and supraalar setal rows, pair of small black triangular posterior marginal spots extending to scutellum; 1+3 dorsocentral setae, anteriormost post-sutural dorsocentral seta near transverse scutal suture, presutural dorsocentral seta before horizontal level of presutural acrostichal setulae; 1+2 acrostichal setulae (not including prescutellar seta) and in 2 rows, 1st post-sutural acrostichal setulae on transverse scutal suture; prescutellar seta shorter than anteriormost postsutural dorsocentral seta; dorsocentral seta, acrostichal setulae and prescutellar seta each with 1 brown basal spots. Anepisternum and katepisternum brown with grayish pruinosity; anepisternum with 2 brown spots on upper margin and 1 brown spot on lower margin, 2 anepisternal setae (posterior anepisternal seta strong) and 3–4 short setulae; 2 katepisternal setae. Scutellum shiny blackish brown, with grayish white pruinosity on basal 1/4. Legs yellow, femur brown and only yellow at tip, apical tarsomeres brown; femur with brown subapical spot on inner side corresponding to subbasal ring on tibia. Fore femur with 5 strong posterior ventral setae and 6 posterior dorsal setae; fore tibia with 1 long dorsal preapical seta and 2 short apical ventral setae. Mid femur with 5 anterior setae and 1 apical posterior seta; mid tibia with 1 strong dorsal preapical seta and 1 strong apical ventral seta. Hind femur with 2 strong anterior ventral setae and 1 preapi- cal anterior dorsal seta; hind tibia with 1 dorsal preapical seta and 1 short apical ventral seta. Wing ( Fig. 2 ) brown, with 9 white radiating stripes along margin between tips of R 2+3 and CuA 1 ; irregular hyaline spots of different sizes in brown central area; costa with 2nd (between R 1 and R 2+3 ), 3rd (between R 2+3 and R 4+5 ) and 4th (between R 4+5 and M 1 ) sections in proportion of 3.5: 1.3: 1; r-m beyond middle of discal cell; ultimate and penultimate sections of M 1 in proportion of 1.8: 1; ultimate section of CuA 1 about 1/6 of penultimate. Halter brown, stem yellow. FIGURES 1–5. Noeetomima hongshanensis sp. nov. Male. 1. head, anterior view; 2. wing; 3. habitus, lateral view; 4. thorax, dorsal view; 5. abdomen, dorsal view.

Male. 6. syntergosternite and epandrium, lateral view; 7. epandrial complex, posterior view; 8. syntergosternite, anterior view; 9. aedeagal complex, ventral view; 10. aedeagal complex, lateral view. Scale 0.5 mm. Abdomen ( Fig. 5 ) blackish brown, but syntergosternite and epandrium yellow; tergites 2–6 with grayish white median spot on anterior margin, 4 pairs of grayish white spots and 4–5 pairs of setae on posterior margin. Male genitalia ( Figs. 6–10 ): syntergosternite slender, circular with pair of ventral processes in anterior view. Surstylus consisting of 1 anterior process and 1 posteroapical process in lateral view; anterior process long with setae, digitiform, posterior process short, widening apically and truncated; hypandrium broad, H-shaped. Gonopod claviform and slender, slightly curved inwards in ventral view (curved slightly dorsally in lateral view), with 4 long setulae; phallus without apical concavity, with a curved sclerite at apex, vertical to phallus. Phallapodeme as long as 1/2 length of phallus. Type material. Holotype ( CAUC ): 1 ♂ , CHINA , Yunnan Province : Xiaozhongdian Hongshan forestry farm, 2012. VI. 11 , Zehui Kang. Paratypes ( CAUC ): 1♂ , 1♀ , CHINA , Sichuan Province : Emeishan Leidongping, 2010. VI . 27 , Tao Li. Distribution. China ( Yunnan , Sichuan ) Remarks. The new species is very similar to Noeetomima thaiensis Sasakawa from Thailand , but N. hongshanensis can be separated from the latter by the fore femur having 5 posterior ventral setae and the hind femur having 2 anterior ventral setae. Etymology. The specific epithet is named for the holotype locality Hongshan.
