Figs 108–109View Figs 102 – 109, 129–133View Figs 129 – 133, 140–142View Figs 134 – 142


Distinguished from similar species (other species in the Ph. krabi  group) by morphology of male palps ( Figs 129–130View Figs 129 – 133; long trochanter apophysis; distinctive shapes of simple round uncus and small appendix; procursus strongly bent dorsad, with distinctive prolatero-ventral pointed process and fringed membranous distal elements) and by unique median sclerite in internal female genitalia visible through cuticle ( Figs 132View Figs 129 – 133, 140View Figs 134 – 142).


The species name is derived from the type locality; noun in apposition.

Male (holotype)

MEASUREMENTS. Total body length 3.7, carapace width 0.9. Leg 1: 32.1 (7.5 + 0.4 + 7.4 + 14.3 + 2.5), tibia 2: 4.5, tibia 3: 2.5, tibia 4: 4.1; tibia 1 L/d: 84. Distance PME-PME 270 µm, diameter PME 95 µm, distance PME-ALE ~35 µm; AME absent.

COLOR. Carapace pale whitish to gray with pair of light brown marks, ocular area and clypeus not darkened; sternum whitish; palps orange; legs pale ochre-yellow with dark patellae and tibia-metatarsus joints; abdomen pale gray with some indistinct darker marks dorsally.

BODY. Habitus as in Fig. 108View Figs 102 – 109; ocular area slightly raised and each triad on low hump; carapace without median furrow; clypeus unmodified; sternum wider than long (0.60/0.50), unmodified.

CHELICERAE. As in Fig. 131View Figs 129 – 133, with small proximal processes and pair of rounded distal apophyses without modified hairs.

PALPS. As in Figs 129–130View Figs 129 – 133; coxa unmodified; trochanter with very long retrolatero-ventral apophysis with retrolateral process proximally; femur with small retrolatero-ventral process proximally; tibia large; procursus strongly bent dorsad, with distinctive prolatero-ventral pointed process and fringed membranous distal elements; bulb with strong proximal sclerite, with small uncus and small appendix, short weakly sclerotized embolus.

LEGS. Without spines and curved hairs; few vertical hairs; retrolateral trichobothrium on tibia 1 at 3%; prolateral trichobothrium absent on tibia 1, present on other tibiae; tarsus 1 with> 30 pseudosegments, only distally fairly distinct.


In general similar to male ( Fig. 109View Figs 102 – 109) but eye triads closer together (PME-PME distance: 195 µm), entire clypeus and ocular area frontally black; legs pale ochre, less yellowish. Tibia 1: 6.7, 6.9 (missing in other females). Epigynum weakly sclerotized almost flat plate with posterior ‘knob’, internal distinctive median sclerite visible through cuticle ( Figs 132View Figs 129 – 133, 140–141View Figs 134 – 142); internal genitalia as in Figs 133View Figs 129 – 133 and 142View Figs 134 – 142.

Natural history

Of the four webs seen at Poring, three had their apex connected to the underside of a leaf; the fourth (of the only male) was freely suspended among the twigs at about 1.5 m above the ground.


Known from two localities in Sabah  ( Fig. 110View Fig. 110).
