Etymology. The specific name refers to the bright receptacula seminis in the holotype female (Ancient Greek “norops” means “bright, flashing, gleaming”); term (adjective) in apposition.

Diagnosis (see also diagnosis for singaporensis -group above). Females similar to P. singaporensis in having a rather simple median septum (MS) and medium sized copulatory ducts (CD). Distinguished by the spermathecal heads (SH) arising upon spermatheca and the narrower copulatory ducts (CD) ( Fig. 19b View FIGURES 19 ).

Description. Male: unknown.

Female:

Body and eye measurements. Carapace length 5.5, carapace width 3.8, anterior width of carapace 2.4, opisthosoma length 7.8, opisthosoma width 3.1. Eyes: AME 0.34, ALE 0.37, PME 0.39, PLE 0.37, AME–AME

0.19, AME–ALE 0.08, PME–PME 0.27, PME–PLE 0.35, AME–PME 0.52, ALE–PLE 0.43, clypeus height at AME 0.69, clypeus height at ALE 0.58.

Cheliceral furrow with three promarginal and four retromarginal teeth.

Measurements of palp and legs. Leg formula: 1423. Palp: 6.6 [2.2, 0.9, 1.2, 2.3]; Legs: I 37.3 [10.0, 2.3, 10.4, 9.3, 5.3], II 28.0 [8.0, 2.0, 7.4, 6.8, 3.8], III 20.3 [5.9, 1.4, 5.0, 4.8, 2.7], IV 30.3 [8.6, 1.8, 7.8, 7.6, 4.5].

Spination. Palp: 131, 110, 1101, 1014; legs: femur I 656, II 655, III–IV 555; patella I–IV 000; tibia I–II 3038, III–IV 3136; metatarsus I–IV 3035.

Copulatory organ (see also diagnosis and general description of singaporensis -group). MS more or less rectangular. Copulatory openings small and narrow ( Fig. 19a View FIGURES 19 ). Slit sense organs and epigynal muscle sigilla outside epigynal field, but close by. CD with ca. 1/3 winding until reaching receptaculum ( Fig. 19b View FIGURES 19 ).

Colouration (see also description for singaporensis -group and Psechrus ). Median bands on carapace at most slightly serrated. Width of lateral bands ca. 1.2x diameter of PME and at most slightly serrated.

Distribution. Malaysia ( Fig. 99 View FIGURE 99 ).
