Diagnosis
Easily distinguished from most congeners by distinctive transversal sclerite on procursus ( Fig. 83 View Figs 82 – 85 ); from the very similar Pa. kubah sp. nov. by other details of procursus (prolateral ridges on procursus, Fig. 82 View Figs 82 – 85 ; small transparent process close to transversal sclerite, Fig. 82 View Figs 82 – 85 ; absence of long membranous prolateral process; distal element shorter). Females are easily distinguished from Pa. nigrifrons by short scape but difFcult to distinguish externally from other congeners in Sarawak (distinctive shape of pore plates and pair of median sclerites; similar only in Pa. kubah sp. nov.).
Etymology
Named for Francis Seow-Choen from Singapore, surgeon and expert on stick insects.
Type material
MALAYSIA-BORNEO: holotype, Ƌ, Sarawak, Mt. Penrissen near Borneo Highland Resort, Ma Gaseng Trail (1.124–1.127° N, 110.217° E), 870–930 m a.s.l., 14 Jul. 2014 (B.A. Huber, S.B. Huber), ZFMK ( Ar 14589 ) GoogleMaps .
Other material examined
MALAYSIA-BORNEO, Sarawak: 1 Ƌ, 4 ♀♀, 1 juv., same data as holotype, ZFMK ( Ar 14590-91 ) GoogleMaps ; 3 ♀♀, 1 juv., same data, in absolute ethanol, ZFMK ( Bor 217 ) GoogleMaps .
Description
Male (holotype)
MEASUREMENTS. Total body length 4.3, carapace width 1.1. Leg 1: 46.3 (10.4 + 0.5 + 10.5 + 22.1 + 2.8), tibia 2: 6.5, tibia 3: 3.7, tibia 4: 5.7; tibia 1 L/d: 114. Distance PME–PME 375 µm, diameter PME 105 µm, distance PME–ALE ~45 µm; AME absent.
COLOR. Carapace pale ochre yellow to whitish, posterior mark ( Fig. 65 View Figs 61 – 68 ) lost in ethanol, ocular area and clypeus dark brown (black in life), with pair of black marks in AME area; sternum whitish; legs ochreorange with dark brown patellae and tibia-metatarsus joints; abdomen ochre-gray, with black marks dorsally, monochromous ventrally.
BODY. Habitus as in Figs 65–66; ocular area raised, each triad on medium long stalk, without pointed process ( Fig. 7); carapace without median furrow; clypeus unmodiFed; sternum wider than long (0.70/0.60), unmodiFed.
CHELICERAE. Similar to close relatives, with proximal pair of processes and distinctively bipartite distal apophyses (cf. Fig. 71 View Figs 69 – 73 ); without modiFed hairs; without stridulatory ridges.
PALPS. In general very similar to Pa. kubah sp. nov. (cf. Figs 69–70 View Figs 69 – 73 ), but trochanter apophysis slightly shorter and distally thinner/more pointed; procursus with distinctive prolateral ridges ( Fig. 82 View Figs 82 – 85 ), with small transparent process close to transversal sclerite ( Fig. 82 View Figs 82 – 85 ), without long membranous prolateral process, entire distal element shorter ( Fig. 83 View Figs 82 – 85 ); bulbal processes apparently not distinguishable from those in Pa. kubah sp. nov.
LEGS. Without spines and curved hairs; few vertical hairs; retrolateral trichobothrium on tibia 1 at 2%; prolateral trichobothrium absent on tibia 1, present on other tibiae; tarsus 1> 40 pseudosegments, proximally very indistinct.
Variation
Tibia 1 in other male: 10.3; other male paler and transversal sclerite of procursus without proximal process.
Female
In general similar to male but eye triads on low humps, much closer together (distance PME–PME 230 µm). Tibia 1 in 3 females: 7.8, 8.4, 8.8. Epigynum weakly sclerotized plate with large weakly sclerotized posterior ‘knob’ ( Figs 84 View Figs 82 – 85 , 92 View Figs 86 – 94 ), internal arch and transversal folds visible through cuticle; internal genitalia as in Figs 85 View Figs 82 – 85 , 93–94 View Figs 86 – 94 .
Natural history
The domed webs were found under green leaves among vegetation, usually about 0.5 m above the ground.
Distribution
Known from type locality in Sarawak only ( Fig. 1 View Fig. 1 ).
