Twenty-seven species of Acridoidea from 20 genera were sequenced to obtain mtDNA data, along with four species from the GenBank nucleotide database. The purpose of this study was analyzing the phylogenetic relationships among subfamilies within Pamphagidae and interpreting the phylogenetic position of this family within the Acridoidea superfamily. Phylogenetic trees were reconstructed using neighbor-joining （NJ）, maximurn parsimony （MP） and Bayesian inference （BI） methods. The 684 bp analyzed fragment included 126 parsimony informative sites. Sequences diverged 1.0%-11.1% between genera within subfamilies, and 8.8%-12.3% between subfamilies. Amino acid sequence diverged 0-6.1% between genera within subfamilies, and 0.4%-7.5% between subfamilies. Our phylogenetic trees revealed the monophyly of Pamphagidae and three distinct major groups within this family. Moreover, several well supported and stable clades were found in Pamphagidae. The global clustering results were similar to that obtained through classical morphological classification： Prionotropisinae, Thrinchinae and Pamphaginae were monophyletic groups. However, the current genus Filchnerella （Prionotropisinae） was not a monophyletic group and the genus Asiotmethis （Prionotropisinae） was a sister group of the genus Thrinchus （Thrinchinae）. Further molec- ular and morphological studies are required to clarify the phylogenetic relationships of the genera Filchnerella and Asiotmethis.展开更多

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
