Bioacoustics of Calapnita mae

Description. Male ( holotype ) MEASUREMENTS. Total body length 6.3, carapace width 0.85. Leg 1 missing, tibia 2: 6.0, tibia 3: 3.1, tibia 4: 6.4. Distance PME-PME 230 µm, diameter PME 80 µm, distance PME-ALE ~30 µm; no trace of AME. COLOR. Entire animal mostly pale gray to whitish, sternum darker, legs slightly yellowish with brown patellae and tibia-metatarsus joints. BODY. Habitus as in C. nunezae (cf. Fig. 133 ); ocular area barely elevated, each triad on very low hump; carapace without median furrow; clypeus unmodified; sternum as wide as long (0.50), unmodified. CHELICERAE. As in Figs 249–250 , 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. 251 , with small tubercles on subdistal hump; femur as in Fig. 248 , distal process at 26% of femur length; tibia length/diameter 0.53/0.31; procursus as in Figs 245–247 , with prolateral process, ventro-distal flat sclerite with distinctive prolateral oblique ridge (arrow in Fig. 245 ); bulb length 0.37; embolus length 0.50. LEGS. Without spines and curved hairs; few vertical hairs. Male (variation). Tibia 1 in 5 other males: 7.1–7.7 (mean 7.4). Female . In general similar to male but sternum whitish; eye triads barely closer together (distance PME-PME 220 µm). Tibia 1 in 16 females : 5.2–6.5 (mean 5.9). Epigynum as in Fig. 252 , weakly sclerotized, wide anterior ‘knob’; internal genitalia as in Fig. 253 , with oval pore plates converging anteriorly.

Description. Male ( holotype ) MEASUREMENTS. Total body length 5.9, carapace width 0.80. Leg 1: 30.0 (8.5 + 0.4 + 7.6 + 13.8 + 2.7), tibia 2: 6.0, tibia 3: 3.7, tibia 4: 6.5; tibia 1 L/d: 109. Distance PME-PME 210 µm, diameter PME 90 µm, distance PME- ALE ~30 µm; no trace of AME. COLOR. Entire animal mostly pale gray to whitish, sternum darker, legs slightly yellowish with brown patellae and tibia-metatarsus joints. BODY. Habitus as in Fig. 133 ; ocular area barely elevated, each triad on very low hump; carapace without median furrow; clypeus unmodified; sternum as wide as long (0.50), unmodified. CHELICERAE. As in Figs 259–260 , with pair of bipartite apophyses near lamellae, 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 ) but smaller; trochanter apophysis as in Fig. 257 , with tiny tubercles; femur as in Fig. 258 , distal process at 28% of femur length; tibia length/diameter 0.53/0.31; procursus as in Figs 254–256 , with semitransparent prolateral process, with globular ventro-distal sclerite; bulb length 0.34; embolus length 0.55. LEGS. Without spines and curved hairs; few vertical hairs; retrolateral trichobothrium on tibia 1 at 2.5%; prolateral trichobothrium absent on tibia 1, present on other tibiae; tarsus 1 pseudosegments not visible in dissecting microscope. Male (variation). Tibia 1 in 23 other males: 6.9–8.0 (mean 7.6). In males from Mount Matutum and Santo Domingo the globular ventro-distal sclerite on the procursus is slightly larger. Female . In general similar to male but sternum whitish; eye triads slightly closer together (distance PME-PME 200 µm). Tibia 1 in 29 females : 5.6–6.7 (mean 6.2). Epigynum as in Figs 261 and 280 , weakly sclerotized with wide anterior ‘knob’; internal genitalia as in Fig. 262 , with almost round pore plates. Natural history . At the type locality, this species was found mostly on Araceae leaves. At Malangob, it shared plants (and sometimes individual leaves) with Pholcus domingo . When disturbed, specimens did not vibrate but pressed their bodies against the leaf surface. If disturbance persisted, they run away and/or reluctantly dropped on a silk line. Two egg-sacs contained 9 and 13 eggs respectively; proximally, a few eggs were side by side, but the distal 4– 6 eggs were in a single row ( Fig. 132 ).
