( Fig. 4 ) http://lsid.speciesfile.org/urn:lsid:Orthoptera.speciesfile.org:TaxonName:477200 Male. Body medium sized. Head with rather thin, elongate rostral tubercles, which completely depressed to each other and protruding forwards ( Fig. 4 A–B). Lateral ocelli oblong, occupying basal two-thirds of lateral surface of rostral tubercles ( Fig. 4 B); median ocellus nearly triangular, the length slightly longer than scape ( Fig. 4 A). Prontoum with broadly rounded ventral margins; lateral parts of mesonotum mat ( Fig. 4 C). Armament of legs: fa 1; ff v1 a; ft v2 o– 1i , v2 a; mf v2 a; mt de, di, d2a, v2 o, v2 a; ht v19 o (17o)– 17i ( 16i ), d2sa, d2a, v4 a; d4c (3c), dac. Hind femora unarmed on ventral surface; inner apical spines of hind tibiae longer than outer ones, dorsal ones about 2.3–2.4 times longer than ventral ones ( Fig. 4 D). Posterior margin of eighth abdominal tergite with a small angular median process ( Fig. 4 E); posterior margin of ninth abdominal tergite with a trapezoidal median process, which basal area broad, narrowing, lateral margins oblique, posterior margin nearly straight ( Fig. 4 E); apical area of tenth abdominal tergite projecting backwards, posterior margin slightly concave. Epiproct nearly triangular, its apex slightly bent downwards and acute. Cerci long, conical, apices acute. Subgenital plate longer than broad, posterior margin slightly convex, styli long and cylindrical with a longitudinal groove on ventral surface ( Fig. 4 F–G). FIGURE 4.

Measurement (mm). BL ♂ 22.5; PL ♂ 7.0; FFL ♂ 8.4; HFL ♂ 17.0; HTL ♂ 15.5; HBL ♂ 4.3. Material examined. Holotype : male, Xima Town , Yingjiang County , Yunnan Province , China , 2 August , 2009, coll. by Ming Qiu & Ruilian Li. Distribution. China ( Yunnan ). Discussion. Within the genus Eurhaphidophora , the new species is easily recognizable and differs from E. laosi , E. ampla and E. orlovi in: male eighth abdominal tergite with weak angular median process ( Fig. 4 E); ninth abdominal tergite broad, posterior margin with a trapezoidal median process which apical area not widened, dorsal surface of the process nearly smooth and lateral margins almost straight ( Fig. 4 E); epiproct nearly triangular. In E. laosi the median process of male ninth abdominal tergite is wider and shorter, nearly rectangular ( Fig. 1 L); and the posterior margin of epiproct is obtusely rounded ( Fig. 2 E). The male of E. ampla has a weak longitudinal median concavity on dorsal surface of median process of ninth abdominal tergite and apical area of the median process obviously widened ( Fig. 1 M). While E. orlovi , the male ninth abdominal tergite is narrow and entirely separated from the median process ( Fig. 1 O), the lateral margins of median process is obviously concave in the middle forming widened apex ( Fig. 1 O), and the epiproct has larger apical lobes ( Fig. 2 K). Etymology. Name derived from the truncated posterior margin of male ninth abdominal tergite.
