Material examined. CHINA: YUNNAN: 1 ♀, ‘China: Yunnan, Baoshan City, Tengchong County, Mingguang Town, Zizhi Village. 25°43′46″N, 98°34′17″E, 1900 m, 26.iv.2013, Dai, Song & Peng leg.’ ( SNUC).

Description. Each compound eye composed of approximately 55 ommatidia. Antenna elongate, lacking distinct club and modification; antennomere 1 thick, subcylindrical, 2–8 each elongate, 8 smallest, 9–11 slightly broadened, with relatively dense setae, 11 largest, slightly longer than 9 and 10 combined (41:38), nearly fusiform. Legs lacking modification; tergite 2–4 (V–VII) each in middle with one large spine before posterior margin, tergite 5 (VIII) flat ( Fig. 6F View Fig ), sub-trapezoidal, posterior margin emarginate and with small nodule in middle; sternite 6 (VIII) transverse ( Fig. 6G View Fig ), posterior margin broadly emarginate, in middle with pair of small nodules. Measurements: body length 3.80 mm; length/width of head 0.68/ 0.79 mm, pronotum 0.75/ 0.96 mm, elytra 1.03/ 1.20 mm; abdomen 1.31/ 1.11 mm; length of antenna 2.04 mm; maximum width of genital complex ( Fig. 6H View Fig ) 0.35 mm.

Comments. This female ( Figs 6E–H View Fig ) is similar to that of F. myanmarensis in the presence of dorsal spines on tergites 2–4 (V–VII), but is distinctly smaller in size (3.80 mm vs. 4.06–4.12 mm) and has differently shaped tergite 5 (VIII) and sternite 6 (VIII).
