Dasyhippus daluoshanensis sp. nov. ( Figs. a – h )

Type materials Holotype: 1♂, paratypes 1♂, 6♀, Daluoshan , Wuzhong, Ningxia, China. 2006-VII-10 collected by Xinjiang Li & Daochuan Zhang.

Male. The body small in size (fig. a), head smaller, shorter than the pronotum. Frons slightly oblique in profile. Vertex narrower, apex acuted (fig. b). The width between eyes is 2 times than the width of frontal costa between antennae. Fastigial foveolae square, the length of fastigial foveolae 3 times as long as width. Lateral margin of frontal ridge parallel above median ocellus and gradually widened toward clypeus, with longitudinal groove. Eyes oval, vertical diameter 1.4 times than transverse diameter and subocular suture. Antennae clubbed, reached the posterior margin of the pronotum, which the widest part is 1.5 times the narrowest part (fig. c). The anterior margin of pronotum straight, posterior margin cambered. Both median carina and lateral carinae distinct, widest of between lateral carinae is 1.8 times than that of narrowest, prozona 1.3 times longer than metazoan (fig. b). The length of mesosternal interspace is 1.1 times than width, metasternal lobes partially connected. Tegmina shorter, reaching 2/3 of the hind femur (fig. a). Precostal area not reaching the median of tegmina. Costal area wider 1.5 times than medial area. Medial area and cubital area equal in width. Anterior and posterior cubitus separate (fig. e). Fore tibia slightly larger than middle tibia, without slender villi. Hind femur with stridulatory pegs in inner lower carinula. Hind tibia with 12 spines on inner side and 13 spines on outer side, external apical spine absent. The first hind tarsus lengths slightly shorter than the combined other two tarsi. Tympanal developed, with semicircular lobe. Epiproct triangular, with longitudinal groove in median (fig. f). Cerci short tapered, reached the epiproct apex. Subgenital plate short conical. Epiphallus shown in Figure g .

Female. Size larger than male (fig. h). Head short, Vertex nearly rectangular. Antennae not reaching the posterior margin of pronotum, the apex slightly enlarged. Posterior sulcus located behind the midsection of pronotum, prozona 1.1 times that of metazona. Tegmina shorter, not reached the posterior margin of the fourth tergite. Ovipositor short, apex sharped.

Coloration. Body yellowish brown. The apex of the antenna dark brown. Subocular furrow with white stripes. Pronotum yellowish brown. A yellowish-white spot in the lateral lobe of pronotum. The base of tegmina costal area with white stripe. Hind femur and tibia yellowish brown. Male anal plate black.

Measurement (in mm): Body: ♂ 16.0 – 16.9, ♀ 19.5 – 20.3. Tegmina: ♂ 8.2 – 9.0, ♀ 6.3 – 8.5. Hind femur: ♂ 9.4 – 10.1, ♀ 10.7 – 11.5.

Diagnosis. The new species is similar to Dasyhippus barbipes ( Fischer von Waldheim, 1846) . The major differences are listed in Table 1 .

Etymology. The specific epithet is named after Daluoshan, the type locality.
