Pseudotachycines trapezialis sp. nov.

( Figs. 18–20 )

Description. Male. Body medium sized. Vertex of head divided into conical tubercles. Legs elongate and slender; fore femora about 1.4 times as long as the pronotum, beneath unarmed, internal knee lobe with a small spine, genicular lobe with 1 elongate movable spur; fore tibiae beneath with 2 external and 2 internal spurs. Mid femora with an elongate movable spur on the internal and genicular lobe, beneath unarmed; mid tibiae beneath with 2 external and 1 internal spur(s). Hind femora beneath with 2 inter spines and without outer spines; hind tibiae above with 64–69 outer and inter spines respectively, arrange in groups, inner subapical spur of hind tibiae slightly longer than hind metatarsus. Hind metatarsus keeled beneath and with an apical spine above. Male epiproct shorter than paraproct ( Fig. 18 ). Dorsolateral lobes of male genitalia sclerotized and epiphallus trapezoidal ( Fig. 19 ).

Female. Subgenital plate subquadrate, both side of the base projected and apex acutely pointed ( Fig. 20 ). Ovipositor longer than the half of hind femora.

Coloration. Body darkish brown. Face and legs light brown.

Measurements. (length in mm) Body ♂ 10.0, ♀ 14.0; pronotum ♂ 5.5, ♀ 6.5; fore femora ♂ 7.5, ♀ 6.5–8.0; hind femora ♂ 15.0, ♀ 22.0; ovipositor 12.5.

Material examined. Holotype, 1♂, Funiu Mountain , Henan, alt. 1400–1700m, 2009. VIII.2, collected by Zhu Wei-Bing; paratype, 1♂, same data as holotype.

Distribution. China (Henan).

Diagnosis. This species is closely related to Pseudotachycines ovalilobatus (Gorochov, 2010) comb. nov., but differences from the latter in that: hind tibiae armed with 64–69 spines each side above and subgenital plate of female subquadrate.
