This paper provides a morphological description of a newly recorded species from Taiwan, Cheiracanthium insigne O. Pickard-Cambridge, 1874, based on newly collected materials. Both male and female C. insigne specimens are analysed, redescribed, and photographed. We applied DNA barcoding validation for matching sexes and reviewed taxonomic issues of...

A new species belonging to the liocranid genus Jacaena Thorell, 1897, J. guiyang sp. nov., is described from southwestern China. A detailed description, diagnosis, photographs, and distribution map of the new species are given. DNA barcodes of the species were obtained and confirmed matching of the sexes, and are available for future use.

... DNA barcoding of spiders has been commonly used in the identification of species or delimitation of similar species, association of separate sexes and specimens collected at different localities (Zhang & Li 2014;He et al. 2016;Coddington et al. 2016;Tyagi et al. 2019;Zhang et al. 2020;Wang et al. 2021). Lo et al. (2021) applied DNA barcoding information to correct sex matching of Cheiracanthium insigne O. Pickard-Cambridge, 1874, the results showing that the significance of integrated morphological and the standard barcode sequence can be used as an effective tool for the identification of species and correctly matching sexes in species of Cheiracanthium. ...
... The genus Cheiracanthium is the most diverse among cheiracanthiids, with 214 extant species and represent 59% of the total number of species of Cheiracanthiidae (World Spider Catalog 2022). Due to cryptic habitat and almost half of the species are known from a single sex or juveniles, the identification of species in Cheiracanthium is often challenging (Zhang et al. 2020;Lo et al. 2021). All interspecific divergences were well above the largest intraspecific values (minimum interspecific 7.4% vs 1.2%). ...
... respectively (Lo et al. 2021). Therefore, the combination of DNA barcodes with locality information may ease the identification of species of Cheiracanthium. ...
Five species of the cheiracanthiid spider genus Cheiracanthium C.L. Koch, 1839 collected from China are diagnosed and described as new to science based on morphological characters: Cheiracanthium arcilongum sp. nov. (♂♀) from Yunnan, C. circulum sp. nov. (♂♀) from Yunnan, C. digitatum sp. nov. (♂♀) from Anhui, C. jiuquan sp. nov. (♂♀) from Guangxi and C. xinjiangense sp. nov. (♂♀) from Xinjiang. In addition, the photos of the habitus, copulatory organs and distribution map are provided for all species. However, DNA barcodes information is only provided for four species.
