Redescription of Borboropactus jiangyong Yin, Peng, Yan & Kim, 2004 (Araneae, Thomisidae), with the first description of the male

Abstract

The male of Borboropactus jiangyong Yin, Peng, Yan & Kim, 2004 is described for the first time from Jinggang Mountain, Ji’an City, Jiangxi Province, China. Based on male and female specimens, the species is redescribed, comprehensively illustrated, and its geographic distribution in China is delimited and discussed.

Two new thomisid species (Arachnida, Araneae, Thomisidae) from China and Vietnam, with the first descriptions of the males of Borboropactus longidens Tang & Li, 2010 and Stephanopis xiangzhouica Liu, 2022

“…The body length of all specimens was taken from the anterior margin of the clypeus to the posterior end of the abdomen, excluding the spinnerets. Terminology of the male and female genitalia follows Benjamin (2011) , Meng et al (2019) , and Liu et al (2022c) . Leg measurements are given as total length (femur, patella, tibia, metatarsus, tarsus).…”

“…China not only has the most species- and genus-rich thomisid fauna, but for approximately 65%, only one of the sexes has been described, which represents a challenge for future taxonomic revisions ( Li 2020 ). However, only a few papers ( Meng et al 2019 ; Wang et al 2020 ; Liu et al 2022c ; Lin et al 2022 ) have revised the species of these single-sex species, and there are still many poorly known species from southern China with unusual morphological characteristics ( Liu et al 2022a ).…”

Notes on two species of Massuria Thorell, 1887 (Arachnida, Araneae, Thomisidae) from China with description of a new species

“…Many new taxa have been discovered, which means that more taxa need to be revised, re-assigned, or supplemented with appropriate identification methods; one such family is the crab spiders Thomisidae Sundevall, 1833. Although there are several recent publications dealing with descriptions of previously unknown sexes of Chinese crab spiders, there are still many species requiring study ( Meng et al 2019 ; Wang et al 2020 ; Lin et al 2022 ; Liu et al 2022b ; Zhong et al 2022 ).…”
