For full reference list see World Spider Catalog (2023).    Diagnosis The male of  Phintella pygmaea( Wesołowska, 1981)resembles that of  P. arcuata Huang, Wang & Peng, 2015in having a similar habitus and palp, but it can be distinguished by: (1) the lamellar process being longer than wide ( Fig. 24A), whereas wider than long in  P. arcuata( Huang et al.2015: figs 1c, 3a); (2) the embolus being straight in ventral view ( Fig. 24A), whereas slightly curved medially in  P. arcuata( Huang et al.2015: figs 1c, 3a). The female also resembles that of  P. arcuata, but it can be easily distinguished by the proximal half of the copulatory ducts being horizontally extended ( Fig. 25A–B), whereas diagonally extended in  P. arcuata( Huang et al.2015: figs 4b, 5a).    Material examined   CHINA• 4 ♀♀, 5 ♂♂; Guangdong, Guangzhou City, Baiyun District, Baiyun Mountain; 23°11.95′ N, 113°17.58′ E;  29 ma.s.l.;  3 Jul. 2019; W.H.
