Diagnosis
Distinguished from similar species (with pair of straight pointed processes arising from near PME and ventral apophysis on male palpal femur: Pa. bako ; Pa. niah sp. nov.; Pa. pueh sp. nov.; Pa. sedgwicki ; Pa. tahai comb. nov.) by longer palpal segments (especially femur and procursus; Figs 33–34 View Figs 33 – 34 ), by shapes of procursus and appendix ( Figs 33–34 View Figs 33 – 34 ), and by longer epigynal scape ( Figs 36–37 View Figs 35 – 37 ; female of Pa. sedgwicki unknown); from very similar Pa. sedgwicki (male holotype examined) by distal structures of procursus, more slender male palpal tibia, and more distal ventral femur apophysis.
Etymology
Named for the type locality; noun in apposition.
Type material
MALAYSIA-BORNEO: holotype, Ƌ, Sarawak, near Kapit, forest along river (1.937–1.944° N, 112.904– 112.910° E), 80–120 m a.s.l, 20 Jul. 2014 (B.A. Huber, S.B. Huber), ZFMK ( Ar 14582 ) GoogleMaps .
Other material examined
MALAYSIA-BORNEO: Sarawak: 8 ƋƋ, 6 ♀♀, 2 juvs, same data as holotype, ZFMK ( Ar 14583-84 GoogleMaps ; 7 ƋƋ, 5 ♀♀) and SMK (1 Ƌ, 1 ♀) GoogleMaps ; 1 Ƌ, 3 ♀♀, 1 juv., same data, in absolute ethanol, ZFMK ( Bor 184 ) GoogleMaps .
Description
Male (holotype)
MEASUREMENTS. Total body length 5.2, carapace width 1.2. Leg 1: 49.9 (11.1 + 0.5 + 11.6 + 23.8 + 2.9), tibia 2: 7.0, tibia 3: 4.1, tibia 4: 6.3; tibia 1 L/d: 110. Distance PME–PME 520 µm, diameter PME 115 µm, distance PME–ALE ~45 µm; AME absent.
COLOR. Carapace pale ochre yellow to whitish, posterior mark ( Fig. 11 View Figs 8 – 15 ) lost in ethanol, ocular area and clypeus dark brown (black in life), without black spots in AME area; 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 Figs 10–11 View Figs 8 – 15 ; ocular area raised, each triad on long stalk, with pointed straight process arising from near PME ( Fig. 4 View Figs 2 – 7 ); carapace without median furrow; clypeus unmodiFed; sternum wider than long (0.75/0.55), unmodiFed. ALS as in Fig. 44 View Figs 38 – 45. — 38 – 41 .
CHELICERAE. Similar to close relatives, with proximal pair of processes and with distinctively biFd distal apophyses ( Figs 35 View Figs 35 – 37 , 46–47 View Figs 46 – 51 ); without modiFed hairs; without stridulatory ridges.
PALPS. As in Figs 33–34 View Figs 33 – 34 ; coxa unmodiFed; trochanter with slightly curved pointed retrolatero-ventral apophysis; femur with ventral apophysis; procursus very long, with row of about 18 ventral ridges ( Fig. 49 View Figs 46 – 51 ) and isolated patch of few prolateral ridges, with distinctive distal processes ( Figs 48–49, 51 View Figs 46 – 51 ), apparently without process in distal pit ( Fig. 42 View Figs 38 – 45. — 38 – 41 ); bulb with strong proximal sclerite, long slender appendix with hooked tip ( Fig. 50 View Figs 46 – 51 ), and long partly sclerotized embolus with short distal fringes ( Fig. 51 View Figs 46 – 51 ).
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 8 other males: 10.6–11.9 (mean 11.3). Some males with black spots in AME area; abdominal marks variably distinct.
Female
In general similar to male but eye triads on low humps, much closer together (distance PME–PME 220 µm), without pointed processes. Tibia 1 in 6 females: 7.9–8.4 (mean 8.2). Epigynum weakly sclerotized plate with variably sclerotized posterior ‘knob’ on extensible scape ( Figs 36 View Figs 35 – 37 , 58 View Figs 52 – 60 ), internal anterior sclerite and complex transversal folds visible through cuticle; internal genitalia as in Figs 37 View Figs 35 – 37 , 59–60 View Figs 52 – 60 .
Natural history
Webs were found among vegetation close to the ground, with the apex of the domed sheet connected to the underside of a leaf. Large numbers of Cecidomyiidae (deposited in ZFMK) were seen hanging from the silk lines in most webs. Egg sacs were slightly elongated, and contained about 25– 30 eggs each (n = 2).
Distribution
Known from type locality in Sarawak only ( Fig. 1 View Fig. 1 ).
