description: Homoneura (Homoneura) pangae sp. nov.
(Figs 20–28)
Diagnosis. Fore femur with 4 strong posteroventral setae and mid femur with 5 anterior setae; basal edge of brown apical spot on R 2+3 behind vertical level of crossvein dm-cu; surstylus long claviform in lateral view with1–2 long setulae and a few of short hairs.
Description. MALE. Body length 5.0– 5.5 mm, wing length 5.4–5.5 mm.
Head (Fig. 21) yellow. Frons as long as wide; ocellar triangle yellow; ocellar setae proclinate, well developed, as long as posterior fronto-orbital setae; anterior fronto-orbital setae slightly shorter than posterior fronto-orbital setae; gena about 1/8 height of eye. Antenna yellow inner side and yellowish brown outer side, 1 st flagellomere 2.0 times longer than height; arista dark except for brownish basally, plumose with longest rays slightly shorter than height of 1 st flagellomere. Proboscis yellow, with yellowish and blackish setulae; palpus yellow, with blackish setulae.
Thorax (Fig. 22) yellow. Mesonotum with 0+3 dorsocentral setae (anteriormost dorsocentral setae distinctly behind transverse suture), acrostichal setulae in 8 rows, prescutellar acrostichal seta longer than anteriormost dorsocentral seta. Legs yellow, tarsi brownish yellow. Fore femur with 4 strong posteroventral setae, 8 posterodorsal setae, and ctenidium with 15–17 short seta; fore tibia with 1 long preapical anterodorsal seta and 1 short apicoventral seta. Mid femur with 5 anterior setae and 1 apical posterior seta; mid tibia with 1 strong preapical anterodorsal seta and 3 strong apicoventral setae. Hind femur with 1–3 anteroventral setae and 1 preapical anterodorsal seta; hind tibia with 1 preapical anterodorsal seta and 1 short apicoventral seta. Wing (Fig. 20) pale yellow, brown apical spot on R 2+3 seperated from that on R 4+5, apical spots on R 4+5 and M 1 slightly confluent or separated; a quadrate spot on R 4+5, at middle point of distance between crossveins r-m and dm-cu; wide brown stripe on crossvein dm-cu, distinctly constricted at middle or one side of brown stripe constricted at middle; subcostal cell pale brown; 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 5.1:1.4:1; r-m before middle of discal cell; ultimate and penultimate sections of M 1 in proportion of 1:1.6; ultimate section of CuA 1 about 1/6 of penultimate. Halter yellow.
Abdomen (Fig. 20) pale yellow. Male genitalia (Figs 23–28): syntergosternite 7+8 a semicircular ring with a few of dorsal setulae and 2–3 setulae around spiracle; epandrium slender; surstylus long claviform in lateral view with1–2 long setulae and a few of short hairs; hypandrium nearly reverse V–shaped; pregonite broad medially with a long setulae in ventral view and postgonite absent; phallus dorsally with a pair of medial processes consisting of two subuliform processes in different length in ventral view; phallapodeme very short and slender.
Type material. Holotype ♂ (USNM), CHINA, Kiangsi S., Wong Sa Shui, 9. VII. 1936, A. L. Melander (N 24°53'49.73", E 115°36'27.77"). Paratype: 1 ♂ (USNM), CHINA, Tien Mu Shan (Zhejiang Province, Tianmushan), 26. V. 1937, A. L. Melander (N 30°12'3.28", E 119°29'48.32").
Distribution. China (Jiangxi, Zhejiang).
Remarks. The new species is similar to Homoneura (Homoneura) henanensis Yang, Zhu & Hu from Henan Province, but the latter has the following characters: the arista has the longest rays as long as the height of the 1 st flagellomere; the surstylus consists of a tapering-slender outer process and a slender curved knife-like inner process; the pregonite is longer than the postgonite, the pregonite has several teeth-like processes and the postgonite is only pointed apically; the phallus is narrow and curved apically (Yang, Zhu & Hu, 1999).
Etymology. The new species is named after the family name of the author Li Shi’s mother Bing Ying Pang. She supports Li Shi’s research on the insects and helps to take care of her children with all her strength and selfless love.
