Rhaphidophora setiformis sp. nov.

( Figs. 18–23 )

Description. Male. The vertex of head divided into a pair of plate-like processes by a longitudinal furrow. Lateral ocelli occupying almost 2/3 of the whole tubercles. Lateral lobes of pronotum slightly concave, posterior margin roundly blunt. Fore femora without spines, internal genicular lobe with 1 elongate movable spur; fore tibiae beneath with 2 external spurs, 1 internal spur and 2 apical spurs. Internal and external genicular lobe of mid femora both with 1 elongate movable spur, mid tibiae beneath with 2 external spurs, 0 internal spur and 2 apical spurs, above with 2 external spurs, 2 internal spurs and 2 apical spurs. Internal genicular lobe of hind femora with a small spine, hind tibiae with 18–19 internal spines and 18 external spines above, arrange sparsely. Supra inner-apical spur of hind tibiae longer than hind metatarsus. Hind metatarsus compressed and with 3 small spines and 1 apical spine dorsally. The distance between the paired styli shorter than styli. Epiproct with 1 longitudinal furrow from base to apex, apex blunt ( Fig. 20 ). Male genitalia with 4-row bristles vertically on dorsal surface ( Figs. 21–22 ).

Female. Subgenital plate nearly triangular, apex pointed ( Fig. 23 ).

Coloration. Body dark brown. Frons dark, clypeus white. Lateral ocelli yellowish. Legs with some streaks. Measurements. (length in mm) Body ♂ 16.0–18.0, ♀ 15.0–17.0; pronotum ♂ 7.5–8.0, ♀ 6.5–7.0; fore femora

♂ 9.0–10.5, ♀ 7.5; hind femora ♂ 20.0–21.0, ♀ 18.5; hind tibiae ♂ 18.0–20.0, ♀ 16.5; hind metatarsus ♂ 3.5–4.0,

♀ 4.0.

Specimens studied. Holotype, 1♂, Bubeng, Xishuangbanna, Yunnan, alt. 600m, 2009-VI-4 ~6, collected by Liu, Wu, Zhu & Bi; paratypes, 1♂, same data as holotype; 2♂♂, Menglun, Xishuangbanna , Yunnan, alt. 1000m, 2009-VI-3, collected by Liu, Wu, Zhu & Bi; 1♀, Menglun, Jinghong, Yunnan, 1991-IX-6, collected by Liu Zu-Yao, Wang Tian-Qi and Yin Hai-Sheng; 1♀, Mengla, Yunnan, 1995-VII-23 ~VII-27, collected by Liu Xian-Wei, Zhang Wei-Nian and Jin Xing-Bao.

Distribution. China (Yunnan).

Diagnosis. This species is very similar with Rhaphidophora mariae Gorochov, 1999 and Rhaphidophora sinica Bey-Bienko, 1962 , but differs in apex of male epiproct ( Fig. 20 ), male genitalia with 4 rows of bristles vertically on dorsal surface ( Fig. 21 ).

Etymology. The new specific epithet derived from Latin name ‘ setiformis ’, meaning male genitalia with many bristles on dorsal surface.
