Description on two species of genus Platythomisus (Araneae, Thomisidae) from China and Singapore

Abstract

Two species of the genus Platythomisus Doleschall, 1859 are studied: P.xiandao Lin & Li, sp. nov. is described based on male and female specimens from Yunnan, China, and P.octomaculatus (C. L. Koch, 1845), the type species of the genus, is redescribed based on female specimens from Singapore. Its male, also from Singapore, is described for the first time.

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

“…More than 50% of the Chinese species are from southern provinces of this country, such as Yunnan, Hainan and Hunan. Only a few percent of the total Chinese number of species have been reported in the past ten years ( Li and Lin 2016 ; Liu et al 2017 , 2022b , 2022c ; Yu and Zhang 2017 ; Yu et al 2017 ; Tian et al 2018 ; Lin et al 2019 , 2022 ; Huang and Lin 2020 ; Wang et al 2020 ; Liu et al 2021 ; Zhang et al 2022 ). 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 ).…”
