In this paper we report one new species from Yunnan Province. All the type specimens are deposited in Guangxi Normal University.

This paper reports two new species based on new material deposited in Guangxi Normal University, namely Metriogryllacris (Metriogryllacris) obscurata sp. nov. (Chinese name: �­纹姬蟋螽) and M. (M.) hamata sp. nov. (Chinese name: 小钩姬蟋螽). Also, the female sex of M. (M.) bimacula Yu, Liu & Bian, 2022 and male sex of M. (M.) nigrilimbis Liu & Bian, 2021 are firstly described.

In this paper we propose two new synonyms based on the new specimens deposited in Guangxi Normal University, viz. Ocellarnaca nigra Shi & Zhu, 2021 syn. nov. and Ocellarnaca fallax (Liu, 1999) syn. nov.. Also, Ocellarnaca brachyptera Shi & Zhu, 2021 is regarded as subspecies of Ocellarnaca emeiensis. In addition, the male genitalia of two known species are illustrated. The previously unknown female sex of Ocellarnaca emeiensis brachyptera Shi & Zhu, 2021 is described and illustrated.

Neohirasea stephanus belongs to the subfamily Necrosciinae in phasmida, which is the most abundant subfamily. In this study, the mitochondrial genome of Neohirasea stephanus was obtained, and its gene structure, protein-coding genes, nucleic acid composition and codon usage were analyzed, while the secondary structure of rRNAs was predicted, and the published complete mitochondrial genomes of 31 stick and leaf insects were compared and analyzed. In addition, the phylogenetic relationships were revealed based on 34 mitochondrial genome data sets by using the Bayesian inference method (BI). The results indicated that N. stephanus and N. japonica are the sister group, and the subfamily Clitumninae, Eurycanthinae and Lonchodinae are a polyphyletic group. According to the time calibrated phylogenetic estimation, the divergence time of Euphasmatodea is inferred to have started ~ 112.55 Mya. This study enriched the mitochondrial genome data of the subfamily Necrosciinae and provided a molecular reference for the future phylogenetic study of stick insects.

This paper is further study Chinese Anabropsinae and proposes two new subgenera of Anabropsis from China, Anabropsis (Spinanabropsis) subgen. nov. and Anabropsis (Pseudapteranabropsis) subgen. nov.. Five new species are described, namely Anabropsis (Apteranabropsis) daweishanensis sp. nov., Anabropsis (Spinanabropsis) pengi sp. nov., Anabropsis (Spinanabropsis) erythronota sp. nov., Anabropsis (Pseudapteranabropsis) nigrimaculatis sp. nov. and Anabropsis (Pseudapteranabropsis) flavimaculata sp. nov. All the specimens are deposited in Guangxi Normal University.
