description: Calapnita bohol sp. nov. Figs 129–130, 228–235
Diagnosis. Distinguished from other species of vermiformis group by tip of procursus (ventral flap bilobed; Fig. 228) and by oval pore plates in transversal orientation (Fig. 235; similar only in C. bugis). From C. bario and C. bariengi also by distal cheliceral apophyses clearly bipartite (Fig. 232); from C. saluang and C. bugis also by wide proximal part of bipartite cheliceral apophyses (Fig. 232); from several species also by continuous wide connection between epigynal plate and ‘knob’ (Fig. 234), and by pale male sternum.
Etymology. The species name is derived from the type locality; noun in apposition.
Material examined. Holotype. PHILIPPINES: ♂, ZFMK (Ar 16046), Bohol Island, near Loboc, at Loboc River (9.651°N, 124.022°E), on leaf, 20 m a.s.l., 4.iii.2014 (B.A. Huber).
Other material. PHILIPPINES: 1♂ 4♀, ZFMK (Ar 16047), same data as holotype; 3♀ in absolute ethanol, ZFMK (Phi 200), same data. 2♀, ZFMK (Ar 16048), Bohol Island, Rajah Sikatuna (Magsaysay Park) (9.705°N, 124.123°E), 430 m a.s.l., forest, on leaves, 6.iii.2014 (B.A. Huber); 1♀ 1 juv. in absolute ethanol, ZFMK (Phi 195), same data. 1♂ 1♀ 7 juvs, ZFMK (Ar 16049), Bohol, Garcia Hernandez, Barangay Datag, ‘sites 2–5’ (~ 9.719°N, 124.262°E), 520–550 m a.s.l., 8.vi.2015 (M.R.B. Dacar). 3♀, ZFMK (Ar 16050), Bohol, Sierra Bullones, Barangay Nan-od, ‘sites 1, 2, 5’ (~ 9.747°N, 124.263°E), 550–610 m a.s.l., 4–5.vi.2015 (M.R.B. Dacar). 2♀, ZFMK (Ar 16051) and 1♀ 7 juvs, MSU-IIT, Bohol, Valencia, Barangay Marawis, ‘sites 4 & 5’ (~ 9.723°N, 124.201°E), 450 m a.s.l., 11.vi.2015 (M.R.B. Dacar).
Description. Male (holotype)
MEASUREMENTS. Total body length 5.9, carapace width 0.75. Leg 1: 32.4 (8.2 + 0.3 + 7.3 + 14.0 + 2.6), tibia 2: 5.6, tibia 3: 3.5, tibia 4: 6.0; tibia 1 L/d: 122. Distance PME-PME 230 µm, diameter PME 90 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. 129; ocular area barely elevated, each triad on very low hump; carapace without median furrow; clypeus unmodified; sternum slightly wider than long (0.50/0.48), unmodified.
CHELICERAE. As in Figs 232–233, with pair of bipartite apophyses near lamellae and pair of lateral humps; 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. 230, with small tubercles and subdistal process; femur as in Fig. 231, distal process at 35% of femur length; tibia length/diameter 0.62/0.33; procursus as in Figs 228–229, ventro-distal sclerite bilobed, i.e. with additional prolateral lobe; bulb length 0.39; embolus length 0.70.
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 not seen in dissecting microscope.
Male (variation). Tibia 1 in 2 other males: 7.2, 7.6.
Female. In general similar to male; eye triads slightly closer together (distance PME-PME 210 µm). Tibia 1 in 9 females: 5.7–6.6 (mean 6.1). Epigynum as in Fig. 234, weakly sclerotized, wide anterior ‘knob’; internal genitalia as in Fig. 235, with distinctive elongate pore plates in transversal orientation.
Natural history. At the type locality, most specimens were collected from taro leaves at a forest edge near the village. Individual leaves were sometimes shared by an unidentified species of Belisana. At this locality, no specimens were found in the forest.
Distribution. Known from Bohol Island only (Fig. 284).
