Calapnita bankirai View in CoL sp. nov. Figs 18 View FIGURES 13 – 19 , 60–64 View FIGURES 55 – 64

Calapnita phyllicola View in CoL ” Deeleman-Reinhold, 1986 (misidentification): Deeleman-Reinhold 1986: 216 (part of paratypes). Huber 2011: 54 (part of paratypes and specimens from Balikpapan in ZFMK, see below).

Diagnosis. Distinguished from most other species of phyllicola group (except C. bidayuh , C. phyllicola , C. semengoh ) by shape of appendix (widely curved with two ventral tines; Fig. 62 View FIGURES 55 – 64 ), by male palpal tarsal organ on cylindrical process of tarsus, by serrated edge of embolus, and by drop-shaped pore plates ( Fig. 64 View FIGURES 55 – 64 ); from closest known relatives ( C. bidayuh , C. phyllicola , C. semengoh ) by narrow tip of procursus ( Fig. 61 View FIGURES 55 – 64 ); from C. phyllicola also by presence of split hairs dorsally on procursus; from C. semengoh also by much shorter palpal segments and external female genitalia; from C. bidayuh also by absence of distal spine-like process on procursus. Females differ from C. phyllicola by absence of sclerotized transversal ridges on epigynum ( Fig. 63 View FIGURES 55 – 64 ) and by pore plates farther apart ( Fig. 64 View FIGURES 55 – 64 ); females of C. bidayuh and C. bankirai may not be distinguishable externally, but the pore plates in C. bankirai are slightly closer together ( Fig. 64 View FIGURES 55 – 64 ).

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

Description. Male (holotype)

MEASUREMENTS. Total body length 5.2, carapace width 0.8. Leg 1: 35.1 (8.3 + 0.3 + 8.5 + 16.3 + 1.7), tibia 2: 5.9, tibia 3: 3.3, tibia 4: 5.2; tibia 1 L/d: 106. Distance PME-PME 240 µm, diameter PME 90 µm, distance PME- ALE ~30 µm; no trace of AME.

COLOR. Entire animal mostly very pale whitish, legs slightly yellowish, patellae and tibia-metatarsus joints with short brown rings.

BODY. Habitus as in Fig. 18 View FIGURES 13 – 19 ; ocular area barely elevated, each triad on very low hump; carapace without median furrow; clypeus unmodified; sternum as wide as long (0.44), unmodified.

CHELICERAE. As in C. phyllicola (cf. fig. 172 in Huber 2011), with pair of simple apophyses near lamellae and pair of indistinct lateral humps proximally; without modified hairs; without stridulatory ridges.

PALPS. In general very similar to C. phyllicola (cf. figs 170–171 in Huber 2011); proximal segments apparently indistinguishable; procursus with two split hairs dorsally and with slender mostly weakly sclerotized tip ( Figs 60– 61 View FIGURES 55 – 64 ); appendix very slender, especially distally ( Fig. 62 View FIGURES 55 – 64 ).

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 pseudosegments very indistinct, only distally a few visible in dissecting microscope.

Male (variation). Tibia 1 in 11 other males: 7.0–8.5 (mean 7.6).

Female. In general similar to male; eye triads slightly closer together (distance PME-PME 210 µm). Tibia 1 in 9 females: 5.4–6.7 (mean 6.0). Epigynum very simple, very similar to C. bidayuh , almost entirely unsclerotized ( Fig. 63 View FIGURES 55 – 64 ); with simple short posterior ‘knob’; internal genitalia as in Fig. 64 View FIGURES 55 – 64 , with pair of membranous ‘sacs’. Natural history. At the type locality the spiders were found on the undersides of palm leaves. One male had an ectoparasitic mite on its prosoma ( Fig. 18 View FIGURES 13 – 19 ; cf. C. dinagat below).

Distribution. Apparently widespread in Borneo, but known from only two localities ( Fig. 282 View FIGURE 282 ).
