( Fig. 2 View FIGURE 2 )

Type material (3 exx). HOLOTYPE: CHINA: ♂ , ‘ China: S. Zhejiang, Longquan City, Fengyang Shan, Da-Tian- Ping (AƁNj), 27°54’36”N, 119°10’20”E, bush leaf, moss, ferns, sifted & beating, 1320 m, 27.iv.2014, Peng, Song, Yan, Yin & Yu leg.’ ( SNUC) GoogleMaps . PARATYPES: CHINA: 2 ♂♂, same label data as holotype expect for ‘ Longquan, Fengyang Shan N.R., forest nr. Datianping , 27°54’33”–55’18”N, 119°10’20”–17”E, 1170–1300 m, 6.x.2013, Feng, Peng, Yin, Yu leg.’ ( SNUC) .

Diagnostic description. Male. Body ( Fig. 2A View FIGURE 2 ) red-brown, mouthparts and tarsi paler. Body length 2.00– 2.18 mm. Head slightly wider than long, length from anterior margin of clypeus to base 0.40–0.41 mm, width across eyes 0.46–0.49 mm. Each eye composed of about 20 facets. Length of eyes (0.17 mm) / length of tempora (0.12 mm) approximately 1.4:1. Length of antennae 1.03–1.07 mm; club ( Fig. 2B View FIGURE 2 ) formed by antennomeres 9–11; antennomere 9 ( Fig. 2C View FIGURE 2 ) slightly elongate, inner margin angularly expanded mesally, with one semi-membranous apophysis at apex of expansion; antennomere 10 strongly transverse, obconical; antennomere 11 ( Fig. 2B View FIGURE 2 ) about 1.9 times as long as wide, with two truncate basal protuberances, the more basal one covered with two tufts of specialized setae at apex ( Fig. 2D View FIGURE 2 ). Pronotum slightly longer than broad, length along midline 0.62–0.65 mm, maximum width 0.61– 0.61 mm. Elytra transverse, length along suture 0.91–0.95 mm, maximum width 1.07–1.10 mm. Abdomen widest at tergite 1 ( IV), and narrowing apically; mid-length of dorsally exposed part 0.73–0.76 mm, maximum width 0.90–0.93 mm. Length of aedeagus ( Fig. 2E View FIGURE 2 ) 0.22 mm; median lobe almost symmetric, with angularly protuberant apex.

Female. Unknown.

Comparative notes. The new species is morphologically most similar to Sathytes tangliangi Yin & Li at Gaoligong Mountain (AE ṈṄƜ), Yunnan in the forms of antennomeres 9 and 11, e.g., the basal protuberances of antennomere 11 of both species are slightly concave at their apices. The two species can be readily separated by the much smaller body size of S. fenghuang (2.00– 2.18 mm vs. 2.80 mm). Sathytes fenghuang is also similar to S. excavatus Löbl from Pokhara, Nepal in the body size and structure of antennomere 11, but may be separated form it by the much more elongate antennomeres 9 and 11, and the distribution.

Distribution. China: Zhejiang.

Etymology. The new specific epithet ‘fenghuang (DZAE)’ means the Chinese phoenix, from which the name of Fengyang Mountain is originated.
