Diagnosis
The male of Phintella pygmaea (Wesołowska, 1981) resembles that of P. arcuata Huang, Wang & Peng, 2015 in 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).

Chelicerae with two promarginal teeth and one retromarginal tooth, and distal flange of fang (Fig. 25G). Legs pale to dark brown. Abdomen elongate-oval, dorsum dark brown, with three transverse bands formed by setae medially and arc-shaped yellow band posteriorly; venter slightly paler than dorsum (Fig. 25C–D).
PALP. Tibia longer than wide; RTA tapered, curved towards bulb distally and pointed apically in ventral view; bulb elongated; posterior lobe beak-shaped, with blunt terminus; tegular bump lamellar, medio-retrolaterally located; lamellar process almost semicircular; embolus straight, short (Fig. 24).

Distribution
China (Guangdong, Guizhou, Hainan) (Fig. 59).
