Diagnosis

The male of Phintella liui sp. nov. closely resembles that of P. castriesiana (Grube, 1861) in having a similar palp, but differs in: (1) the RTA being slightly curved towards the bulb in ventral view ( Fig. 20A ), whereas curved towards the dorsal side in P. castriesiana ( Logunov & Wesołowska 1992: fig. 28a); (2) the retrolateral margin of the lamellar process being separated from the sperm duct ( Fig. 20A ), whereas partly covers the sperm duct in P. castriesiana ( Logunov & Wesołowska 1992: fig. 28a). The female also resembles that of P. castriesiana in the epigynal structure, but differs in: (1) the epigynal basal plate having two well-developed protrusions ( Fig. 21A–B ), whereas indistinct in P. castriesiana ( Logunov & Wesołowska 1992: fig. 29a); (2) the copulatory ducts being connected to the dorsum of postero-inner edges of spermathecae ( Fig. 21B ), whereas connected to the antero-prolateral edges of spermathecae in P. castriesiana ( Logunov & Wesołowska 1992: fig. 29b–c).

Etymology

The species is named after Mr Tianjun Liu, who helped us a lot to conduct this research; noun (name) in genitive case.
