A phylogenetic tree was inferred by neighbor-joining （N J）. The results of sequences compared show that： （i） in a total of 574 bp of Oedipodidae, the number of substituted nucleotides was 265 bp and the average percentages ofT, C, A and G were 38.3%, 11.4%, 31.8% and 18.5%, respectively, and the content of A＋T （70.1%） was distinctly richer than that of C＋G （29.9%）; and （ii） the average nucleotide divergence of 16S rDNA sequences among genera of Oedipodidae were 9.0%, among families of Acridoidea were 17.0%, and between superfamilies （Tetrigoidea and Acridoidea） were 23.9%, respectively. The phylogenetic tree indicated： （i） the Oedipodidae was a monophyletic group, which suggested that the taxonomic status of this family was confirmed; （ii） the genus Heteropternis separated from the other Oedipodids first and had another unique sound-producing structure in morphology, which is the type-genus of subfamily Heteropterninae; and （iii） the relative intergeneric relationship within the same continent was closer than that of different continents, and between the Eurasian genera and the African genera, was closer than that between Eurasians and Americans.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. The type specimens are deposited in the College of Plant Protection, Shandong Agricultural University, Taian, Shandong, China.展开更多
