Synema guiyang sp. nov., the fourth endemic species of Synema Simon, 1864 (Araneae, Thomisidae) from China

Abstract

Synema Simon, 1864 is a relatively large genus of family Thomisidae Sundevall, 1833 and currently includes 124 species distributed worldwide, except for the Polar Regions. However, Synema can be regarded as being poorly represented in China, with only seven species, three of which are endemic. A new spider species of the genus Synema from Guiyang City in China, is described under the name of S. guiyang J. Zhang, Q. Lu & H. Yu, sp. nov. Detailed descriptions and photographs of the new species are provided. DNA barcodes (a partial fragment of the mitochondrial cytochrome oxidase subunit I gene, COI) of the species were obtained to confirm matching of the sexes and for future use in molecular studies.

A survey of Tmarus Simon, 1875 (Araneae, Thomisidae) from Fanjing Mountain Nature Reserve, Guizhou, China

“…Leg lengths are given as total length (femur, patella, tibia + metatarsus, tarsus). Most of the terminologies used in text and figure legends follows Tang and Li (2009) and Zhang et al (2022) .…”

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 ).…”
