The new species is similar to Chorthippus （Altichorthippus） changtunensis Yin, 1984, but it differs from the latter by： hind femur and tibia orange red, abdomen of male orange red at end and medial area of tegmen is 1.2 times cubital area. The new species is also similar to Ch. （Altichorthippus） tibetanus Uvarov, 1935, but differs from the latter by the lateral carinae of pronotum obvious and angulated in prozona, anterior and posterior transverse carinae not obliterated.展开更多

The new species is similar to Ch. （Altichorthippus） charpini Chang, 1939 and Ch. （Altiehorthippus）jishishanensis Zheng ＆ Xie, 2000, but males differ from both as follows.. length of fastigial foveolae about 3.00 times its width; antennae just not reaching the base of hind femur; apex of elytron extending to the posterior margin of seventh abdominal tergum; widest of costal area 0.67 times widest medial area; apex of hind wing extending to the middle of seventh abdominal tergum; anterior and posterior cubitus connate, cubital area obliterated; cercus reaching middle of epiproct; knee lobe brownish, not black; basal part of hind tibia brownish, not black. The type specimens are deposited in the Institute of Zoology, Shaanxi Normal University.展开更多

The new species is allied to C. rufitibialus Zheng, Ma ＆ Wang 1996. It differs from the latter in male as follows： longitudinal diameter of eye 1.8-1.9 times subocular furrow; widest of pronotum between lateral carinae 2.0 times narrowest; arolium between claws small, slightly not reaching half length of claws; basal part of hind tibia yellowish brown, not black; claws pale blue in basal part. The type specimens are deposited in the Institute of Zoology, Shaanxi Normal University.展开更多

Results show that the chromosome numbers of the two species fit 2n （♂） = 17 = 16 ＋ XO, in which three pairs of autosomal and sex chromosomes were terminal chromosomes, and the other five pairs of autosomes were metacentric chromosomes. These are diagnosis characters for Chorthippus. However, these two species can be distinguished by the different chromosome formula （CF） and the relative length （RL）. The CF in Ch. （M.） aethalinus is K （2n, ♂） = 6m ＋ 11t = 6L ＋ 6M ＋ 4S ＋ XO, whereas that of Ch. （M.） chinensis is K （2n, ♂） = 6m ＋ 11t = 6L ＋ 8M ＋ 2S ＋ XO. In addition, we also found that the relative lengths of sex chromosomes in the two species were different from each other. The sex-chromosome of Ch. （M.） aethalinus is located at the fifth position and its relative length is 8.33% whereas that of Ch. （M.） chinensis is at the eighth position and its relative length is 5.53%. These results show that significantly different genetic features exist for the two species of Chorthippus.展开更多

The new species is similar to C.（A.） changtunensis Yin, 1984, but different by： prozona longer than metazoan, maximum width of medial area of tegmen about 2 times as maximum width of cubital area in male, base of hind femur without dark sloping stripe on inner side and length of interspace of mesosterum shorter than minimum width in female. A new combination Magaulacobothrus tianshanensis（Zheng, Ma ＆ Ren, 2009） comb. nov. is reported.

It was found that immediately before jumping M. alpina executes primarily unilateral object-related peering movements, with approximately twice the amplitude and velocity of the predominantly bilateral object-related peering movements of the other two species. Whereas M. alpina almost always jumped toward the black stripes in the experimental arena, the other species jumped toward both the black stripes and the white spaces between them. All three species preferred the same pattern of black stripes, which permitted them to view one black stripe frontally, with an additional black stripe to the left and right, in the lateral visual field. The similarities and differences in the peering-jump behavior of the three grasshopper species is discussed with regard to visual perception （parallax cues） and environmental adaptation.展开更多
