... classification of Grylloidea and Gryllotalpoidea from China", in which 9 species were recorded including arisanicus, aspersus, beybienkoi, hemelytrus, latefasciatus, micado, ornatus, parvus, yunnanensis (Yin & Liu 1995). V. hemelytrus is a misidentification of V. ornatus and V. latefasciatus is only the morphological variation of V. micado (see Fig. 1c). V. yunnanensis was synonymized as V. flavifrons by Gorochov (2001). Additionally, V. parvus should be moved into genus Vietacheta and newly named as V. harpophylla ( Ma et al. 2015). Xie and Zhang et al. reported the V. curvinervis and V. bannaensis from Guangxi and Yunnan province respectively ( Xie 2004, Zhang et al. 2017). Thus, ...

The Chinese burrowing-cricket Velarifictorus beybienkoi is newly found in Korea. Previously, it was only known on the east coast of China, but is now confirmed on the midwest of Korea. Compared to other Velarifictorus species in Korea, V. beybienkoi can be distinguished by shortest tegmina of both sexes and male genitalia. Redescription, figures of the species are provided to aid in identification and the male calling songs are analyzed for the first time.

A new genus (Mirigryllus He gen. nov.) with a new species (M. nigrus He sp. nov.) is reported from Zhejiang, China. The morphology and calling songs of the new species are provided. The features that different from tribe Modicogryllini spp. include long and thin posterior epiphallic lobes, ectoparameron transparent. Two genes, COI and 18S, of 11 Modicogryllini species were sequenced, and phylogenetic tree was reconstructed. The results support the validation of the new species. The type specimens are deposited in Museum of Biology, East China Normal University (ECNU).
There are hundreds of filiform mechanosensory hairs on the cricket cercus, however, such sensory hairs have never been reported on cricket foretiba. In this study, we collected a new species from China, which possesses two long filiform hairs on foretibia. Combined with its burrowing habit, these hairs mainly contribute to detecting ground vibration. We describe a new genus for this new species Fodigryllus bisetus gen. et sp. nov. The type specimens are deposited in the Museum of Biology, East China Normal University (ECNU).
The cricket Velarifictorus micado is widely distributed in East Asia and colonized the United States of America (the USA) in 1959. It has two life cycles: egg and nymph diapause. We aimed to investigate the biogeographic boundary between them and determine when and why V. micado diverged. Mitochondrial fragments including COI and CytB were used for haplotype network, demographic analysis, and divergence time estimation in individuals of East Asia. We selected several samples from the USA to find out the colonization origin. The haplotype network indicated there were three lineages based on COI, NE lineage (the egg diapause and mainly distributed in the northern regions), SE lineage (the egg diapause and mainly distributed in the southern regions), and SN lineage (the nymph diapause and mainly distributed in the southern regions). The molecular chronograms indicated that the first divergence of V. micado into two main lineages, NE and southern lineages (SE and SN), was essentially bounded by the Yangtze River. It occurred around ~0.79 Ma (95% HPD: 1.13–0.46 Ma) in the Middle Pleistocene Transition. This was followed by the divergence of the southern lineage into two sublineages, SE and SN lineage, occurred around ~0.50 Ma (95% HPD: 0.71–0.25 Ma), corresponding to the time of development of glaciers in various parts of the Qinghai–Tibet Plateau (QTP) (0.73–0.46 Ma). SE lineage might originate from southwestern China based on the comparison between the haplotype network based on COI and CytB. Our study suggested that divergences of lineages have twice co‐occurred with tendency of cooling climatic in Asia after the Mid‐Pleistocene, and the life‐history strategy may play an important role in lineage diversification. Additionally, our results indicated that the USA populations were revealed at least twice separate Asian invasions. These both belonged to the egg diapause, which might provide a new perspective for invasion control.
Seven species of the subgenus Duolandrevus (Eulandrevus) Kirby, 1906 have been recorded from China prior to this study. Their morphology is similar, and genitalia can be used for distinguishing different species in earlier research. We describe one new species, D. (E.) obsidianus He sp. nov. from Guangxi. The new species is similar to related species in gross morphology, but showed differences in genitalia with epiphallic lateral lobes bifurcated apically in right angle. The songs and COI genes are first compared in this study, and the results support the validity of the new species. The type specimens are deposited in Museum of Biology, East China Normal University (ECNU).
