Type species. Aranea cinerea Fabricius, 1777 , from France .

Comments. Arctosa C.L. Koch, 1847 , with 168 species and two subspecies ( WSC, 2024), is one of the largest genera of Lycosidae . It is a poorly defined and undoubtedly polyphyletic genus ( Wang et al., 2012). Arctosa has an almost worldwide distribution, although it does not occur in Australia. The genus is relatively well studied in Europe ( Lugetti & Tongiorgi, 1965; Almquist, 2005), the Nearctic ( Dondale & Redner, 1983; Paquin & Dupérré, 2003), Japan ( Tanaka, 2009) and Korea ( Namkung, 2003).

Almost one-fifth (32) of all named Arctosa species occur in China ( WSC, 2024). Chinese species have not been revised, and data regarding their taxonomy and distribution is scattered throughout numerous different papers ( Song et al., 1999; Yin et al., 2012; Wang et al., 2012, 2021; Zhang et al., 2022, etc.).

The diversity of Arctosa in Southeast Asia was poorly studied until recently. Currently, five species of this genus are known from this region: Arctosa tanakai Barrion & Litsinger, 1995 ( Philippines), A. delaportei , A. depectinata , A. kiangsiensis , and A. springiosa ( Laos) ( Barrion & Litsinger, 1995, Omelko & Marusik, 2022).
