Diagnosis

The male of Phintella fodingensis sp. nov. resembles that of P. popovi (Prószyński, 1979) , but differs in: (1) the RTA being extended upward in ventral view ( Fig. 15A ), whereas extended diagonally towards bulb in P. popovi ( Peng 2020: fig. 218b); (2) the embolus being straight ( Fig. 15A ), whereas curved medially ( Peng 2020: fig. 218b). The female also resembles that of P. popovi , but differs in the copulatory openings, which are separated from each other by about 1.8 times spermathecal width ( Fig. 16A ), whereas almost touching in P. popovi ( Peng 2020: fig. 218g).

Etymology

The species name is derived from the name of the type locality, Foding Mountain National Nature Reserve; adjective.

Legs: I 5.10 (1.41, 0.75, 1.38, 1.05, 0.51), II 4.47 (1.24, 0.68, 1.13, 0.93, 0.49), III 4.83 (1.34, 0.63, 1.15, 1.22, 0.49), IV 4.99 (1.41, 0.53, 1.25, 1.29, 0.51).

HABITUS. Carapace yellow, covered with white and brown scale-like setae and brown setae, with pale area anteromedially on thorax ( Fig. 16C, F ). Chelicerae with one retromarginal tooth and two promarginal teeth, without distal flange of fang ( Fig. 16G ). Legs pale yellow to yellow except femora and tibiae I brown to dark brown. Abdomen elongate-oval, dorsum pale brown, with a pair of longitudinal, white stripes formed by setae laterally; venter pale gray to pale brown ( Fig. 16C–D ).

PALP. Tibia almost as long as wide in ventral view; RTA strongly curved medially in ventral view, and tapered to pointed tip curved diagonally towards bulb in retrolateral view; bulb slightly broadened posteriorly, with posterior lobe extended downward; tegular bump lamellar; lamellar process about nine times as long as wide; embolus thin and straight, with rather pointed tip almost directed towards 1 o’clock position in ventral view ( Fig. 15 ).
