A survey of Phrurolithidae spiders from Jinggang Mountain National Nature Reserve, Jiangxi Province, China

Abstract

<jats:p>Phrurolithidae spiders were collected from Jinggang Mountain National Nature Reserve, Jiangxi Province, China, during the past six years. The new genus <jats:italic>Alboculus</jats:italic> Liu, <jats:bold>gen. nov.</jats:bold>, with the type species <jats:italic>Phrurolithus zhejiangensis</jats:italic> Song &amp;amp; Kim, 1991, is described, and its previously unknown male is described for the first time. Furthermore, seven new species of <jats:italic>Otacilia</jats:italic> are described: <jats:italic>O. acutangula</jats:italic> Liu, <jats:bold>sp. nov.</jats:bold> (♂♀), <jats:italic>O. bijiashanica</jats:italic> Liu, <jats:bold>sp. nov.</jats:bold> (♂♀), <jats:italic>O. longtanica</jats:italic> Liu, <jats:bold>sp. nov.</jats:bold> (♀), <jats:italic>O. ovoidea</jats:italic> Liu, <jats:bold>sp. nov.</jats:bold> (♂♀), <jats:italic>O. shenshanica</jats:italic> Liu, <jats:bold>sp. nov.</jats:bold> (♂♀), <jats:italic>O. subovoidea</jats:italic> Liu, <jats:bold>sp. nov.</jats:bold> (♂♀), and <jats:italic>O. xiaoxiica</jats:italic> Liu, <jats:bold>sp. nov.</jats:bold> (♀). All species are illustrated with photographs and their distributions are mapped.</jats:p>

A new species of Lysiteles Simon, 1895 (Araneae, Thomisidae) from South China

“…When we collected all illustrated descriptions of the Lysiteles species, one of the interesting findings is that some of them can be assigned in one sub-group by the embolus with a spiral or strongly curved tip and the large RTA longer than the tibia and the female epigyne with the distinct septum dividing the atrium into two large parts, including L. arcuatus Tang, Yin, Peng, Ubick & Griswold, 2008, L. auriculatus , L. corrugus Tang, Yin, Peng, Ubick & Griswold, 2008, L. dentatus Tang, Yin, Peng, Ubick & Griswold, 2007, L. dianicus Song & Zhao, 1994, L. qiuae Song & Wang, 1991, L. silvanus Ono, 1980, L. spirellus , L. subdianicus Tang, Yin, Peng, Ubick & Griswold, 2008, L. subspirellus and L. torsivus ( Song et al 1999 , Tang et al 2007 , Tang et al 2008 , Liu et al 2020c ). Maybe it is a superficial perspective in previous work, but it still needs to be confirmed by future collection and further research.…”

“…From 2015 to 2022, many spider taxa have been discovered by our team in south-central Jiangxi Province, such as Agelenidae ( Liu et al 2020a , Liu et al 2021 ), Dictynidae ( Liu et al 2018 ), Oonopidae ( Liu et al 2016 , Liu et al 2019 ), Phrurolithidae ( Liu et al 2020b , Liu et al 2020c , Liu et al 2021 , Liu et al 2022d ), Salticidae ( Liu et al 2017b , Ying et al 2021 , Liu et al 2022a ), Thomisidae ( Liu et al 2017a , Liu et al 2022c ) and Gnaphosidae ( Liu et al 2022b ). Previous research recorded more than 100 new species in this area and most of them are endemic to this country.…”

A new species of Orthobula Simon, 1897 (Araneae, Trachelidae) from South China

“…Recently, in Jiangxi Province, many spider taxa have been discovered, such as Agelenidae ( Liu et al 2020a , Liu et al 2021 ), Dictynidae ( Liu et al 2018 ), Oonopidae ( Liu et al 2016 , Liu et al 2019 ), Phrurolithidae ( Liu et al 2020b , Liu et al 2020c , Liu et al 2021 , Liu et al 2022d ), Salticidae ( Liu et al 2017b , Liu et al 2022a ), Thomisidae ( Liu et al 2017a , Liu et al 2022c ), Gnaphosidae ( Liu et al 2022b ) and Trachelidae (this study). These discoveries support the fact that this Province is one of the biodiversity hotspots for China.…”

Ground spiders (Araneae, Gnaphosidae) from Jiangxi Province, China

“…In contrast to these areas, species richness of spiders in non-hotspots, such as Jiangxi Province, has not been given enough attention. Recently, in Jiangxi, which has a mountain terrain, many spider taxa have been discovered, such as Agelenidae ( Liu et al 2020a , 2021a ), Dictynidae ( Liu et al 2018 ), Oonopidae ( Liu et al 2016 , 2019 ), Phrurolithidae ( Liu et al 2020b , 2020c , 2021b , 2022a ), Salticidae ( Liu et al 2017b , 2022c ), Thomisidae ( Liu et al 2017a , 2022b ), and Gnaphosidae (this study). These discoveries lend support to mountainous landscapes being refuges for spiders during glacial periods.…”
