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 : 597-599

Microtachycines elongatus sp. nov.

( Figs. 4–9 )

Description. Male. Body rather large. Vertex of head divided into conical tubercles, slightly separated ( Fig. 5 ). Legs long and slender; fore femora about 1.5 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 7–9 inter spines and without outer spines; hind tibiae above with 65–75 outer spines and 66–74 inter spines, arrange in groups, inner subapical spur of hind tibiae almost equal the length of hind metatarsus. Hind metatarsus with bristles beneath and an apical spine above. Epiproct prolong backwards and with a hollow in the middle part from above, apex with a distinct incision ( Fig. 6 ). Lateral lobes of male genitalia distinctly sclerotized ( Fig.7 ), basal part with a large projection ( Fig. 8 ).

Female. Subgential plate nearly trapezoidal and hind margin with a small spine ( Fig. 9 ). Ovipositor shorter than the half of hind femora.

Coloration. Body yellowish brown with dark streaks. Face yellowish with 4 dark longitudinal bands. Legs with dark annular stripes.

Measurements. (length in mm) Body ♂ 15.0, ♀ 14.0; pronotum ♂ 6.0, ♀ 6.0; fore femora ♂ 9.0, ♀ 10.0; hind femora ♂ 16.0, ♀ 18.0; ovipositor 5.5.

Material examined. Holotype, 2♂♂, Qingliangfeng, Linan , Zhejiang, alt . 1000m, 2009. VII.20, collected by Yin Hai-sheng et al.; paratype, 1♂, 2♀♀, same data as holotype ; 1♂, Gutian Mountain, Kaihua , Zhejiang, alt. 330– 800m, 2012. IX.18–20, collected by Liu Xian-wei et al. ; 1♀, Tianmu Mountain , Zhejiang, alt. 350m, 2009. X.14– 15, collected by Liu Xian-wei et al. ; 1♀, Tianmu Mountain , Zhejiang, alt. 1012m, 2010. VII.28–IX.2, collected by Pan Hui.

Distribution. China (Zhejiang).

Discussion. This species is very similar to Microtacheines fallax sp. nov., but differs from the latter in: hind femora armed with 7–9 spines ventrally, outer lobes of male genitalia with a large basal projection.
