摘要
本文记述在新疆发现的蝗虫二新种。新种荒漠蚍蝗Eremippus barbarus sp. nov.,近似于Eremippus apacus Mistsh.及E. foveolatus Mistsht,主要区别为雄性触角中段一节较细,其长为宽的1.9倍;两性前翅较短,其顶端到达后足股节膝部(雄性)或后足2/3处(雌性);又以雄性肛上板顶端较钝区别于E. apacus,以雄性头侧窝较宽(长为宽的1.9倍)区别于E. foveolatus.新种Sphingonotus striatus sp. nov. 近似于盐池束颈蝗sphingonotus yenchihensis cheng et Chiu,主要区别为雄性复眼较长,其长为眼下沟长的2倍;两性后足股节较细长。其长为宽的5倍(雄)或4.4倍(雌);两性自头顶到前胸背板后缘具一宽的黑褐色中央纵纹;前翅无暗色横带纹,后足胫节无明显的暗色环。
Two new species of the genera Eremippus Uv. and Sphingonotus Fieb. (Acrodoidea)were described. All type specimens are preserved in the institute of zoology, Shanxi Normal University. Eremippus Barbarus sp. nov. (Fig. 1～5) This new species is allied to Eremippus apacus Mistsh. and E. foveolatusMistsh., but it differs from them in: 1) a middle antennal segment more slender in male. its ratio of length to width is 1.9; 2) elytra in both sexes shorter. only extending to the knee (in male) or to the 3/4 of hind femur (in female). The new species differs from E. apacus in the apex of epiproct obtuse in male, from E. foveolatus in the feveola wider, the length 1.9 times its width. Length: body: ♂ 9.0 ♀ 12. 2mm; pronotum; ♂2.1, ♀2.54mm; elytra: ♂6.7, ♀7.0mm; hind femur: ♂5. 9, ♀6.7mm. Holotype: ♂, allotype: ♀; Bo-le county. Xinjiang, 1989-Ⅸ-11, collected by Lian Zheng-min. Sphingonotus striatus sp. nov. (Fig. 6～10) This new species is similar to Sphingonotus yenchihensis Cheng et Chiu. but differs in: 1) longitudinal diameter of eye in male 2 times longer than the subocular furrow length; 2) hind femur more slender in both sexes, 4,4(in female) or 5,5(in male) times as long as broad; 3) in both sexes with a broader, dark-brown median strip from vertex to the posterior margin of pronotum; 4) in both sexes, without tranverse darker band on the elytra and evitable dark ring on hind tibia. Length: body: ♂15.3～18.2, ♀23.5～26.5mm; pronotum: ♂3.1～3.4, ♀5.0～5.1mm; elytra: ♂17.2～18.7, ♀24.5～27.0mm; hind femur: ♂8.3～9.0, ♀12.2～12.9mm. Holotype: ♂; allotype: ♀; paratype; 5♂♂: 1♀; Nanhu, Hami city, Xinjiang: 1990-Ⅷ-17, collected by Li Bao-ping
