Qin, Yanyan, Liu, Xianwei & Li, Kai, 2017, Review of the genus Microtachycines Gorochov with two new species (Orthoptera, Rhaphidophoridae, Aemodogryllinae) from China, Zootaxa 4216 (6), pp. 596-600 : 599-600

Microtachycines fallax sp. nov.

( Figs. 10–13 )

Description. Male. Body rather small. Vertex of head divided into conical tubercles, distinctly separated. Legs long and slender; fore femora about 1.6 times as long as the pronotum, beneath unarmed, internal knee lobe with a small spine, genicular lobe with 1 long movable spur; fore tibiae beneath with 2 external and 1 internal spur(s), between the paired apical spurs with a short spur. Mid femora with a long movable spur on the internal and genicular lobe, beneath unarmed; mid tibiae beneath with 1 external and 1 internal spur, between the paired apical spurs with a short spur. Hind femora beneath with 4–6 inter spines and without outer spines; hind tibiae above with 65–69 outer spines and 63–68 inter spines, arrange in groups, inner subapical spur of hind tibiae longer than hind metatarsus. Hind metatarsus with bristles beneath and an apical spine above. Male epiproct nearly trapezoidal, prolong backwards and apex shallowly incised ( Fig. 10 ). Male genitalia sclerotized undistinctly ( Figs. 11–12 ).

Female. Subgential plate nearly round and with blunt apex ( Fig. 13 ). Ovipositor longer than the half of hind femora.

Coloration. Body brown with black streaks. Face light with 4 black longitudinal bands. Legs with black annular stripes.

Measurements. (length in mm) Body ♂ 9.0–11.0, ♀ 12.0; pronotum ♂ 6.0–7.0, ♀ 7.0; fore femora ♂ 9.0–11.0, ♀ 11.0; hind femora ♂ 18.0, ♀ 22.0; ovipositor 13.0.

Material examined. Holotype, 1♂, Jiugongshan, Xianning , Hubei, alt. 1200–1250m, 2016. VII.30, collected by Hu & Liu leg .; paratype, 1♀, same data as holotype ; 2♂♂, Wujiashan, Yingshan , Hubei, alt. 900m, 2014. VI.28, collected by Wang Han-qiang .

Distribution. China (Hubei).

Discussion. This species is very similar to Microtachycines elongatus sp. nov., but differs from the latter in: hind femora armed with 4–6 spines ventrally, outer lobes of male genitalia without basal projection.
