Diagnosis

Distinguished from similar species (with pair of pointed processes arising from near PME and ventral apophysis on male palpal femur: Pa. bako ; Pa. kapit sp. nov.; Pa. niah sp. nov.; Pa. sedgwicki ; Pa. tahai comb. nov.) by details of male pedipalp ( Figs 16–17 View Figs 16 – 20 ; simple conical ventral femur apophysis; distinctive prolateral membranous process on procursus; shape of procursus tip; short appendix, similar only in Pa. niah sp. nov.); from Pa. kapit sp. nov. also by shorter palpal segments and shorter epigynal scape ( Figs 17, 19 View Figs 16 – 20 ). Females are difFcult to distinguish from Pa. bako and Pa. niah sp. nov. (internal transversal folds much more complex in Pa. bako , very similar in Pa. niah sp. nov.; unknown in Pa. sedgwicki ).

Etymology

Named for the type locality; noun in apposition.

Type material

MALAYSIA-BORNEO: holotype, Ƌ, Sarawak, Pueh foothills, forest along river (1.798–1.800° N, 109.708–109.718° E), 100–200 m a.s.l., 16 Jul. 2014 (B.A. Huber, S.B. Huber), ZFMK ( Ar 14575 ) GoogleMaps .

Other material examined

MALAYSIA-BORNEO, Sarawak: 3 ƋƋ, 5 ♀♀, same data as holotype, ZFMK ( Ar 14576-77 ) GoogleMaps ; 1 ♀, 3 juvs, in absolute ethanol, same data, ZFMK ( Bor 231 ) GoogleMaps .

Description

Male (holotype)

MEASUREMENTS. Total body length 5.0, carapace width 1.1. Leg 1: 44.3 (9.9 + 0.5 + 10.2 + 21.1 + 2.6), tibia 2: 6.3, tibia 3: 3.5, tibia 4: 5.8; tibia 1 L/d: 106. Distance PME–PME 490 µm, diameter PME 105 µm, distance PME–ALE ~45 µm; AME absent.

COLOR. Carapace pale ochre yellow to whitish, posterior mark ( Fig. 8 View Figs 8 – 15 ) lost in ethanol, ocular area and clypeus dark brown (black in life); sternum whitish; legs ochre-orange with dark brown patellae and tibia-metatarsus joints; abdomen ochre-gray, with black marks dorsally, monochromous ventrally.

BODY. Habitus as in Fig. 8 View Figs 8 – 15 ; ocular area raised, each triad on long stalk, with pointed straight process arising from near PME ( Figs 2 View Figs 2 – 7 , 18 View Figs 16 – 20 ); carapace without median furrow; clypeus unmodiFed; sternum wider than long (0.7/0.6), unmodiFed. Gonopore with four epiandrous spigots ( Fig. 27 View Figs 21 – 28 ). ALS as in Fig. 28 View Figs 21 – 28 .

CHELICERAE. Similar to close relatives, with proximal pair of processes and with distinctively bipartite distal apophyses ( Fig. 18 View Figs 16 – 20 ); without modiFed hairs; without stridulatory ridges.

PALPS. As in Figs 16–17 View Figs 16 – 20 ; coxa unmodiFed; trochanter with slightly curved retrolatero-ventral apophysis and low retrolateral hump; femur with conical ventral process; procursus with row of about 26 ventral ridges ( Fig. 26 View Figs 21 – 28 ), with distinctive prolateral membranous process and distal elements ( Figs 21–23 View Figs 21 – 28 ); bulb with strong proximal sclerite, short curved appendix, and proximally widened and sclerotized embolus with distal processes and fringes ( Figs 24–26 View Figs 21 – 28 ).

LEGS. Without spines and curved hairs; few vertical hairs; retrolateral trichobothrium on tibia 1 at 1.5%; prolateral trichobothrium absent on tibia 1, present on other tibiae; tarsus 1 with> 40 indistinct pseudosegments.

Variation

Tibia 1 in 3 other males: 8.9, 9.3, 9.6.

Female

In general similar to male but eye triads on low humps, much closer together (distance PME–PME 235 µm), without pointed processes. Tibia 1 in 5 females: 7.6–8.3 (mean 7.9). Epigynum weakly sclerotized plate with large weakly sclerotized posterior ‘knob’ ( Figs 19 View Figs 16 – 20 , 52 View Figs 52 – 60 ), internal arch and transversal folds visible through cuticle; internal genitalia as in Figs 20 View Figs 16 – 20 , 53–54 View Figs 52 – 60 .

Distribution

Known from type locality in Sarawak only ( Fig. 1 View Fig. 1 ).
