Calapnita bario  sp. nov. Figs 120–121View FIGURES 120 – 127, 134–141View FIGURES 134 – 141

Diagnosis. Distinguished from other species of vermiformis  group by very long procursus ( Figs 134View FIGURES 134 – 141, 288View FIGURES 285 – 288); from most species (except C. bariengi  ) also by distal cheliceral apophyses not bipartite ( Fig. 136View FIGURES 134 – 141); from most (except C. dayak  ) also by long and slender palpal tibia (tibia length/width>2.5; Fig. 286View FIGURES 285 – 288); from several species also by narrow and distinct epigynal ‘knob’ ( Fig. 141View FIGURES 134 – 141), and by long internal female genitalia with oval pore plates converging anteriorly and close together ( Fig. 140View FIGURES 134 – 141).

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

Material examined. Holotype.

MALAYSIA-BORNEO: ♂, ZFMKAbout ZFMK ( Ar 16021), Sarawak, Bario  , forest along river N of town (3.765– 3.771°N, 115.444– 115.448°E), 1170–1250 m a.s.l., 29.vii.2014 (B.A. Huber, S.B. Huber).GoogleMaps 

Other material. MALAYSIA-BORNEO: 1♂ 3♀ 4 juvs, ZFMKAbout ZFMK (Ar 16022), same data as holotype  ; 1♀ 2 juvs in absolute ethanol, ZFMKAbout ZFMK (Bor 234), same data  .

Description. Male (holotype)

MEASUREMENTS. Total body length 5.2, carapace width 0.75. Leg 1: 31.8 (7.8 + 0.4 + 7.2 + 13.6 + 2.8), tibia 2: 5.8, tibia 3: 3.6, tibia 4: 6.2; tibia 1 L/d: 103. Distance PME-PME 200 µm, diameter PME 110 µm, distance PME- ALE ~30 µm; no trace of AME.

COLOR. Entire animal pale gray to whitish, legs slightly yellowish with brown patellae and tibia-metatarsus joints.

BODY. Habitus as in Fig. 120View FIGURES 120 – 127; ocular area barely elevated, each triad on very low hump; carapace without median furrow; clypeus unmodified; sternum slightly wider than long (0.52/0.46), unmodified.

CHELICERAE. As in Figs 136–137View FIGURES 134 – 141, apophyses near lamellae not bipartite, with pair of lateral processes; without modified hairs; without stridulatory ridges.

PALPS. In general similar to C. vermiformis  (cf. figs 139 and 140 in Huber 2011); trochanter apophysis as in Fig. 138View FIGURES 134 – 141; femur as in Fig. 139View FIGURES 134 – 141, ventral processes very widely spaced (distal process at 53% of femur length; cf. Fig. 285View FIGURES 285 – 288); tibia length/diameter 0.92/0.33; procursus as in Figs 134–135View FIGURES 134 – 141, very long, with simple ventro-distal flat sclerite; bulb length 0.49; embolus length 1.16; embolus tip with transparent fringes.

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 pseudosegments barely visible in dissecting microscope.

Male (variation). Tibia 1 in other male: 7.4.

Female. In general similar to male; eye triads slightly closer together (distance PME-PME 180 µm). Tibia 1 in 3 females: 6.1, 6.1, 6.2. Epigynum as in Fig. 141View FIGURES 134 – 141, weakly sclerotized triangular plate with small and slender anterior ‘knob’; internal genitalia as in Fig. 140View FIGURES 134 – 141, very long, with pore plates close together and far from posterior margin.

Distribution. Known from type locality in eastern Sarawak only ( Fig. 283View FIGURE 283).
