First mitogenomic characterization of (Orthoptera, Tetrigidae), with the descriptions of two new species.

Classification of species is commonly based on morphological, molecular, and distribution depending on the taxa. Zheng, Wei & Jiang, 2005 and Tinkham, 1937 are both wingless types of Tetrigidae with extremely similar morphological characteristics, and in the current taxonomic system they are placed in two different subfamilies, Metrodorinae and Tetriginae, respectively. It is difficult to clearly identify the species of these two genera by morphological characteristics, and molecular data is often needed to assist identification.

Twenty-three new synonyms of the Eastern common groundhopper, (Bolívar, 1887) (Orthoptera, Tetrigidae).

The Eastern common groundhopper, , is a pygmy grasshopper species widely distributed in the Eastern Palearctic region, and shows a high degree of phenotypic variation. The classification of is difficult and frequently involved errors. Among the many species of Tetrigidae that have been described in China within the last decades, many synonyms of were found.

Pygmy grasshoppers of the genus Xistra Bolvar, 1887 (Orthoptera: Tetrigidae: Metrodorinae).

The genus Xistra Bolvar is reviewed. Two new species from China, Xistra hainanensis Deng, sp. nov.

The complete chloroplast genome of (Orthoptera: Tetrigoidea) from China and its phylogenetic analysis.

The mitochondrial genome (mitogenome) of (Orthoptera: Tetrigoidea) was determined and analyzed. The complete mitochondrial genome is 16,006 bp in length, consisting of 37 genes, including 13 protein-coding (PCGs), 22 tRNA, 2 rRNA genes as well as an A + T-rich region. Ten PCGs initiated with a typical ATN codon (one with ATC, two with ATA, two with ATT, and five with ATG) and 13 terminated with complete stop codons.

Characterization of the complete mitochondrial genome of (Orthoptera: Tetrigoidea) from China and its phylogenetic analysis.

The mitochondrial genome (mitogenome) of the (Orthoptera: Tetrigoidea) was sequenced and annotated. The complete mitogenome has a length of 16,696 bp and consists of 13 protein-coding genes, 2 ribosomal RNA genes, 22 transfer RNA genes, and a A + T-rich region. Thirteen PCGs started with typical ATN codon and ended with complete stop codons (five with TAG, eight with TAA).

Characterization of the complete mitochondrial genome of (Orthoptera: Tetrigidae) from China and its phylogenetic analysis.

The mitochondrial genome (mitogenome) of the (Orthoptera: Tetrigidae: Tetriginae) was sequenced and annotated. The assembled mitochondrial genome was 14,947 bp, containing 45.8% of A, 15.

New species and new synonyms of Macromotettixoides (Orthoptera: Tetrigidae) with an updated key.

The genus Macromotettixoides Zheng, Wei Jiang, 2005 is reviewed. Four new species of the genus, M. daiyunshanensis Deng, sp.

Molecular data provide new insights into the phylogeny of Cladonotinae (Orthoptera: Tetrigoidea) from China with the description of a new genus and species.

Considerable effort has been devoted to elucidating the phylogenetic relationships of tetrigides. However, there is still no commonly accepted phylogenetic hypothesis. Therefore, the phylogenetic relationships among some subfamilies remain unclear; e.

The genes expression difference between winged and wingless bird cherry-oat aphid Rhopalosiphum padi based on transcriptomic data.

Aphids produce wing and wingless morphs, depending on the environmental conditions during their complex life cycles. Wing and wingless variations play an important role in migration and host alternation, affecting the migration and host alternation processes. Several transcriptional studies have concentrated on aphids and sought to determine how an organism perceives environmental cues and responds in a plastic manner, but the underlying mechanisms have remained unclear.
