Qin, Yanyan, Jiang, Huiting, Liu, Xianwei & Li, Kai, 2018, A new genus of Rhaphidophorinae (Orthoptera, Rhaphidophoridae) from China, Zootaxa 4500 (2), pp. 179-194 : 187-188

Rhaphidophora wuzhishanensis sp. nov.

( Figs. 26–28 )

Description. Male. Body medium sized. The vertex of head divided into two flat processes separated by a deep furrow. Lateral ocelli oblong occupying 2/3 of the whole tubercles, middle ocelli oval. Pronotum with deep irregular stripes, lateral lobes slightly concave, posterior margin rather blunt. Fore femora without spines, internal genicular lobe with 1 elongate movable spur, this character just opposite to the Aemodogryllinae (only external genicular lobe with an elongate movable spur on fore femora); fore tibiae beneath with 2 external spurs, 1 internal spur and 2 apical spurs. Mid femora without spines, internal and external genicular lobe both with 1 elongate movable spur; mid tibiae above with 2 external spurs, 2 internal spurs and 2 apical spurs, beneath with 2 external spurs, no internal spur and 2 apical spurs. Hind femora without spines, hind tibiae with 16–18 spines on both sides above, arranged sparsely. Supra inner-apical spur of hind tibiae longer than hind metatarsus and almost exceeding ventral apex of the second tarsus. Hind metatarsus with 5 small spines and 1 apical spine dorsally. Hind margin of 10 th abdominal tergite concave. The basal part of male epiproct nearly oval and middle part slightly hollowed, narrowing to apex, at the apical part with a figure-like process ( Fig. 26 ).

Female. Unknown.

Coloration. Body yellowish brown. Frons light. Middle ocelli and lateral ocelli light creamish. The base of antenna white. Pronotum with dark irregular stripes. Hind femora with some light stripes.

Measurements. (length in mm) Body ♂ 14.5–16.0; pronotum ♂ 6.5–8.0; fore femora ♂ 7.5–9.0; hind femora ♂ 19.0–21.0; hind metatarsus ♂ 4.5.

Specimens studied. Holotype, 1♂, Wuzhishan , Hainan, alt. 800m, 2011-IV-16 ~24, collected by Bi Wen-Xuan; paratype, 1♂, same data as holotype.

Distribution. China (Hainan).

Diagnosis. This species is rather similar to Rhaphidophora insularis Gorochov, 2013 , but differences from the latter in that: male epiproct with apical process more slender; the distance between paired styli shorter than styli, while Rhaphidophora insularis Gorochov, 2013 with styli distinctly shorter than the distance between the paired styli.

Etymology. The new specific epithet derived from where the materials were collected.
