Psechrus kinabalu Levi, 1982

Figs 11a–d , 83e , 84d

Psechrus kinabalu Levi 1982: 126 , figs 54–55 (Description and illustration of ♂). [Holotype ♂ ( SB 237 ) from MALAYSIA: Borneo, Sabah Province: Mt. Kinabalu , 5500 ft. (1680 m); Field-Coll. - No. 5238; E.W. Classey leg. 20.–24.I.1976; NHM 1981˙4˙10˙11, examined].

Revised diagnosis (see also diagnosis for mulu -group above). Male with tegulum (T) converging strongly at (centro-)apical section and merging into embolus base (EB) ( Fig. 11b ). Embolus (E) curved and very slightly serrated ventrally ( Figs 11a,c ). With peculiar bulge proximal to EB ( Figs 11a–b ).

Description. Male:

Body and eye measurements. Carapace length 4.9, carapace width 3.6, anterior width of carapace 1.9, opisthosoma length 5.3, opisthosoma width 2.1. Eyes: AME 0.28, ALE 0.36, PME 0.37, PLE 0.38, AME–AME 0.13, AME–ALE 0.04, PME–PME 0.23, PME–PLE 0.25, AME–PME 0.39, ALE–PLE 0.35, clypeus height at AME 0.54, clypeus height at ALE 0.42.

Cheliceral furrow with three promarginal and four retromarginal teeth.

Measurements of palp and legs. Leg formula: 1423. Palp: 5.7 [2.2, 0.9, 0.9, 1.7]; Legs: I 52.2 [14.0, 2.1, 14.3, 15.6, 7.6], II 39.0 [10.6, 1.7, 10.0, 11.1, 5.6], III 26.7 [7.7, 1.4, 6.4, 7.3, 3.9], IV 43.5 [11.7, 1.7, 10.3, 12.8, 7.0].

Spination. Palp: 131, 110{010}, 0100 (very small); legs: femur I 556, II 556, III 545, IV 545; patella I–IV 000; tibia I 3038, II 3036, III–IV 3136(dorsal one small); metatarsus I–IV 3035.

Palpal femur slim and modified with a ventral, pointed extension ( Fig. 11d ). Palpal tibia relatively short, distally broader than proximally ( Figs 11a–c ). MC-I–II and MT-I absent.

Copulatory organ (see also diagnosis and general description for mulu -group). T shorter than in P. mulu . If viewed from retrolateral ( Fig. 11c ) it seems divided into a narrow distal part, which merges into to EB apically, and a broad and large basal part. Cymbium dorsally with very dense scopula, covering ca. 2/3 of cymbium ( Fig. 83e ).

Female: unknown.

Colouration (see also description for mulu -group and Psechrus ). Median bands on carapace just slightly serrated.

Distribution. Malaysia [Borneo, Sabah Province] ( Fig. 100 ).

Remarks: For the following reason it is unlikely that the male holotype represents the conspecific male of P. borneo: The females of P. mulu and P. borneo are similar. Consequently, for P. borneo I would anticipate a male that is similar to P. mulu . However, this does not apply to P. kinabalu , as its bulb as well as palpal tibia, -patella and -femur differ clearly from those of P. mulu .
