Diagnosis

The male of Phintella fanjingshan Li, Wang, Zhang & Chen, 2019 resembles that of P. pulcherrima Huang, Wang & Peng, 2015 in having a similar habitus and a small lamellar process, but differs in: (1) the RTA is acutely narrowed distally in retrolateral view ( Fig.13B ), whereas tapered in P. pulcherrima ( Huang et al. 2015: figs 8b, 10b); (2) the embolus is almost as long as the lamellar process ( Fig. 13A ), whereas about 1.5 times as short as the lamellar process in P. pulcherrima ( Huang et al. 2015: figs 8a, 10a). The female is similar to that of P. jiugongensis sp. nov., but can be distinguished by the following: (1) the copulatory ducts are about one-third the spermathecal width and slightly curved medially ( Fig. 14B ), whereas about one-forth the spermathecal width, and strongly curved more than 90° in P. jiugongensis ( Fig. 18B ); (2) the epigyne has a pair of eyebrow-shaped atrial ridges anterior to the copulatory openings ( Fig. 14A ), whereas arc-shaped and anteriorly between the copulatory openings in P. jiugongensis ( Fig. 18A ).

HABITUS. Carapace yellow to brown, covered with pale scale-like setae and pale setae anteriorly, with fan-shaped area medially on thorax and a pair of marginal yellow bands laterally ( Fig 14C, F ). Chelicerae with one retromarginal tooth and two promarginal teeth, and distal flange of fang ( Fig. 14G ). Legs pale to red-brown. Abdomen elongated, dorsum pale to green-brown, with alternate pale and green-brown transverse bands and brown terminal spot; venter yellow to pale brown ( Fig. 14C–D ).

PALP. Tibia slightly wider than long in ventral view; RTA tapered in ventral view, broadened basomedially, and acutely narrowed to pointed tip distally in retrolateral view; bulb elongated, with well-developed posterior lobe curved towards postero-retrolaterally in ventral view; tegular bump almost triangular in retrolateral view; lamellar process small, longer than wide; embolus strongly sclerotized, straight, almost as long as lamellar process, blunt apically ( Fig. 13 ).

Female (TRU-JS 0125)

MEASUREMENTS. Total length 4.86. Carapace 1.82 long, 1.32 wide. Abdomen 2.82 long, 1.98 wide. Eye sizes and interdistances: AME 0.45, ALE 0.25, PLE 0.23, AERW 1.25, PERW 1.14, EFL 0.93. Legs: I 3.40 (1.01, 0.58, 0.80, 0.63, 0.38), II 3.16 (1.00, 0.50, 0.75, 0.58, 0.33), III 3.79 (1.15, 0.53, 0.85, 0.88, 0.38), IV 4.18 (1.23, 0.55, 1.01, 1.01, 0.38).

HABITUS. Similar to that of male except paler in color ( Fig. 14E ).

EPIGYNE. With broad, bow-shaped basal plate; copulatory openings almost round, below eyebrow-shaped atrial ridges; copulatory ducts slightly curved medially, with very short accessory glands at terminus; spermathecae pear-shaped, very close to each other medially; fertilization ducts lamellar, originate from anterior edges of spermathecae ( Fig. 14A–B ).
