Figs 20–21, 58

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.

HABITUS. Carapace red-brown, covered with dense white scale-like setae on clypeus and lateral sides of eye field, with anterior and median yellow areas and a pair of later marginal white bands formed by scale-like setae (Fig. 21C, F). Chelicerae with elongated paturon, two promarginal teeth, and one big retromarginal tooth (Fig. 21F–G). Legs I brown to dark brown, remaining legs pale yellow. Abdomen elongated, dorsum green latero-marginally, with pale yellow longitudinal band medially; venter pale yellow, with a pair of dotted lines (Fig. 21C–D).

PALP. Tibia wider than long, dorsally bearing white scale-like setae; RTA tapered, slightly curved to pointed tip; cymbium setose, bearing white scale-like setae at base; bulb elongated; tegular bump lamellar, located retrolatero-basally; lamellar process about four times as long as wide; embolus short, sclerotized, apically directed retrolaterally (Fig. 20).
