Etymology. The species name is derived from the Latin word ‘ validus ’, and refers to the valid RTA; adjective.

Diagnosis. The new species is similar to P. nipponicus Kishida, 1914 ( Kishida, 1914: 124, fig. 1) in having similar bursae, but can be distinguished from the latter by: 1) embolus small, with a large piece of membranous base (concealed behind the conductor); 2) broad, thick RTA extending distally, DTA broad proximally, needle-like apically (only one RTA, thin, long in the latter).

Description. Male ( Fig. 11A View Figure 11 ). Total length 2.38–2.67 (n=10). Holotype: body 2.63 long; carapace 1.17 long, 1.01 wide; abdomen 1.43 long, 0.89 wide. Carapace yellowish brown, anteriorly abruptly narrow; fovea longitudinal, distinct. Eyes sizes and interdistances: AME 0.06, ALE 0.08, PME 0.06, PLE 0.07; AME–AME 0.05, AME–ALE 0.02, PME–PME 0.06, PME–PLE 0.06. MOA 0.17 long, front 0.15 wide, back 0.17 wide. Clypeus 0.09 high. Chelicerae with one strong anterior bristle; promargin with three well-separated teeth and retromargin with two teeth close to each other. Labium and gnathocoxae wider than long, brown.

Leg formula: 4123. Femora I–IV basally with one dorsal spine, femur I with one prolateral spine and femur II without prolateral spine; tibia I with five pairs of ventral spines, tibia II with five proventral spines and four retroventral spines; metatarsus I with four proventral spines and three retroventral spines, metatarsus II with four proventral spines and three retroventral spines. Abdomen oval, anterior half with a small dorsal scutum, posterior half dark brown and with several unclear chevron-like stripes dorsally.

Palp ( Figs 11C–E View Figure 11 , 12A–C View Figure 12 ). Femur distally with an apophysis retroventrally. Thick RTA extending distally, DTA broad proximally, needle-like apically. Embolus sharp apically.

Female ( Fig. 11B View Figure 11 ). Total length 2.67–3.01 (n=11). One paratype: body 2.82 long; carapace 1.24 long, 1.09 wide; abdomen 1.57 long, 0.92 wide.

Epigyne ( Figs 11F–G View Figure 11 , 12D–E View Figure 12 ). COs small, located with a little longer distance from each other than opening diameter. Thin and short CD connecting with two transparent bursae, crescent shaped. Spermathecae small, located centrally.
