Figs 164–171 “ Calapnita vermiformis ” (misidentification; only specimens listed below): Deeleman-Reinhold 1986b : 212 . Huber 2011 : 48 . Diagnosis . Distinguished from most species of vermiformis group (except C. bugis ) by wide obtuse tip of ventral flap of procursus ( Fig. 164 ); from most (except C. bario ) also by long and slender palpal tibia (tibia length/width>2.5; Fig. 286 ); from several species also by very small proximal part of bipartite cheliceral apophyses ( Fig. 168 ), by narrow and distinct epigynal ‘knob’ ( Fig. 170 ), and by oval pore plates converging anteriorly and very close together ( Fig. 171 ). Etymology . Dayak is a loose term for over 200 riverine and hill-dwelling ethnic subgroups located principally in the interior of Borneo; noun in apposition. Material examined. Holotype . INDONESIA-BORNEO: ♂ , RMNH ( ARA 17814), Central Kalimantan , Tumbang Tahai ( 2.033°S , 113.583°E ), primary marshy forest, from leaves, 3/ 13.ix.1985 ( S. Djojosudharmo ). Other material . INDONESIA-BORNEO: 1♂ 1♀ , RMNH ( ARA 17424), same data as holotype . 1♂ 1♀ , RMNH ( ARA 17421), Central Kalimantan , Kaharian ( 2.033°S , 113.667°E ), swampy primary forest, in foliage, 2– 16.ix.1985 ( S. Djojosudharmo ) . 1♂ 1♀ , RMNH ( ARA 17427), Central Kalimantan , 40 km NW Palangkaraya [~ 1.96°S , 113.75°E ?], secondary forest, from leaves, ix.1985 ( S. Djojosudharmo ). Assigned tentatively . INDONESIA-BORNEO: 1♂ 1♀ , ZFMK (Ar 5330), East Kalimantan , Balikpapan [~ 1.25°S , 116.833°E ], primary forest, 20.vii.1982 (Murphy, 11872 part). Description. Male ( holotype ) MEASUREMENTS. Total body length 3.5, carapace width 0.5. Leg 1: 25.4 (6.5 + 0.3 + 5.5 + 10.9 + 2.2), tibia 2: 4.2, tibia 3: 2.6, tibia 4: 4.7; tibia 1 L/d: 110. Distance PME-PME 160 µm, diameter PME 70 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 close congeners (cf. Figs 122, 124 ); ocular area barely elevated, each triad on very low hump; carapace without median furrow; clypeus unmodified; sternum as wide as long (0.40), unmodified. CHELICERAE. As in Figs 168–169 , apophyses near lamellae bipartite with small proximal part, with pair of barely visible 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. 167 ; femur as in Fig. 166 , distal process at 50% of femur length; tibia very slender ( Fig. 286 ), length/diameter 0.44/0.15; procursus as in Figs 164–165 , with simple ventro-distal flat sclerite; bulb length 0.30; embolus length 0.58; embolus tip with distinct fringes. LEGS. Without spines and curved hairs; few vertical hairs; trichobothria on tibia 1 and tarsus 1 pseudosegments not seen. Male (variation). Tibia 1 in 2 other males: 5.5, 6.1. The male from East Kalimantan shares the distinctively slender palpal tibia but is significantly larger and therefore assigned tentatively (tibia 1 missing; palpal tibia length/ diameter 0.59/0.18; bulb length 0.38; embolus length 0.80). Female . In general similar to male, also eye triads at same distance. Tibia 1 in 3 females : 5.5, 5.6, 5.8. Epigynum as in Fig. 170 , weakly sclerotized triangular plate with small and slender anterior ‘knob’; internal genitalia as in Fig. 171 , longer than wide, with oval pore plates close together. Distribution . Known from Central Kalimantan and (specimens assigned tentatively) East Kalimantan ( Fig. 283 ).
