In this paper, a new species, Sichuana cryptospina sp. nov., is described from Sichuan, China. COI genes were used to analyze the phylogenetic relationships with the species belonging to Drymadusini from China. Phylogenetic reconstruction supports the monophyly of Drymadusini while the relationships among genera are still unclear. The new species should be placed in the new genus named Sichuana gen. nov. Additionally, Kansua Uvarov should be moved into this tribe, with supplementary expression of the tribe diagnosis. Types of the new species in this paper are preserved in the Museum of Biology, East China Normal University (ECNU).
In this study, we describe one new species, Sichuana feicui He sp. nov., from Mao County, Sichuan Province, China. This new species is different from S. cryptospina in the shape of cercus, and the color pattern of hind femur. The type specimens are deposited in Museum of Biology, East China Normal University (ECNU).
Phryganogryllacris laoshanica sp. nov. is described from Shandong, China. The new species is the first mesopterous species belonging to the genus Phryganogryllacris. Types of the new species in this paper are deposited in Shanghai Entomological Museum, Chinese Academy of Sciences.
Perlodinella Klapálek, 1912 is a small stonefly genus in the Palearctic areas of China and its biodiversity is underestimated.
This paper reports a new species of Perlodinella, Perlodinella shennongjia sp. nov. in the Dajiuhu National Wetland Park of Shennongjia Forestry District, Hubei Province, central China. The description and illustrations of the new species are provided, based on male adults, female adults and eggs. The new species can be distinguished from its congeners by the characters of male and female genitalia and the egg structure.
In this paper, one new genus, Ptosoproctus gen. nov., is established with two new species: P. lanzhouensis sp. nov. and P. baishishanicus sp. nov., described and illustrated based on material collected from northern China. The genus Eulithoxenus Bey-Bienko, 1951 is recorded from China for the first time. E. emeljanovi Mishchenko, 1968 is redescribed. Supplemental description of Uvarovina chinensis Ramme, 1939 is provided. COI and ND2 genes of the three Chinese Drymadusini genera mentioned above were used to reconstruct the phylogenetic tree. Molecular result support the validation of the new genus.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
