ABSTRACT
The genus Diestramima comprises 41 species from Asia with 31 species distributed in China. In this study, we reconstruct the phylogeny tree of Diestramima species by maximum likelihood and Bayesian inference based on three mitochondrial genes (COI, 12S and 16S). The result indicates that the phylogenetic results are coherent with that based on five molecular markers (COI, 12S, 16S, 18S and 28S). Moreover, two new species, D. pingmengensis sp. nov. He & Zong and D. gulinjingensis. sp. nov. Zong & He are described. Their validities are also supported by morphological features. Furthermore, D. sichuanensis Zhu & Shi, 2022 is treated as a junior synonym of D. guangxiensis Qin, Wang, Liu & Li, 2016 based on both morphological and molecular features.

Hemigyrus was established by Brunner von Wattenwyl in 1893. In this study, we collected samples from Chongqing, Guangxi, Hainan, Sichuan, Tibet and Yunnan of China, and reconstructed phylogenetic tree based on COI gene. The results supported the classification of dividing this genus into two subgenera: Tomomima and Hemigyrus. With larger size and evidently branched phylogenetic position, a new subspecies H. (T.) spinosus robustus subsp. nov. Xie, Wang He is described here. H. (H.) acutifolius is firstly reported from China. Males of H. (H.) amplus and H. (H.) acutifolius, females of H. (H.) minor are described for the first time. All materials were deposited in Biological History Museum of East China Normal University (ECNU) and the Shanghai Entomological Museum, Chinese Academy of Sciences (SEM).

A new genus (Arboramima Zong, Qin He gen. nov.) with a new species (Arboramima cattusis Zong, Qin He sp. nov.) is reported from Guangxi, China. The morphology of the new genus and species are provided. Samples of Aemodogryllinae species were selected for the reconstruction of phylogenetic tree based on mitochondrial COI fragment. The results supported the validation of the new genus. The type specimens are deposited in Museum of Biology, East China Normal University (ECNU).
