Bioacoustics of Panjange dinagat

Description Male ( holotype ) MEASUREMENTS. Total body length 4.4, carapace width 1.0. Leg 1: 33.9 (7.8 + 0.5 + 7.9 + 15.7 + 2.0), tibia 2: 5.0, tibia 3: 2.8, tibia 4: 4.3; tibia 1 L/d: 97. Distance PME–PME 430 µm, diameter PME 90 µm, distance PME–ALE ~50 µm; AME absent. COLOR. Carapace pale ochre yellow to whitish, without posterior mark, ocular area and clypeus dark brown, with black mark in AME area; sternum whitish; legs ochre-yellow with dark brown patellae and tibia-metatarsus joints; abdomen ochre-gray, with black marks dorsally, monochromous ventrally. BODY. Habitus as in Fig. 11 ; ocular area raised, each triad on long stalk, with pointed curved process arising from near PME and directed toward anterior ( Fig. 76 ); carapace without median furrow; clypeus with two patches of modiFed hairs: slightly stronger hairs below black mark and distinct Feld of ~20 short spines more distally; sternum wider than long (0.65/0.50), unmodiFed. CHELICERAE. As in Fig. 76 , with pair of simple, weakly sclerotized processes in rather frontal position directed toward median; without modiFed hairs; without stridulatory ridges. PALPS. As in Figs 74–75 ; symmetric; coxa with strong ventro-distal rim but otherwise unmodiFed; trochanter relatively long, with simple retrolatero-dorsal process and complex retrolatero-ventral apophysis, distally curved toward prolateral, with two distinctive subdistal branches directed toward distal and retrolateral respectively; femur short, with two short dorsal processes and very indistinct prolateral hump; tibia very thick (width ~70% of length); tarsus with short whitish elongation with terminal tarsal organ; procursus proximal part with rounded ventral process, distal part hinged, with distinctive retrolateral process and simple Fat prolateral process; bulb with strong proximal sclerite, long processes extending in opposite directions (dorsal embolus; ventral appendix), with retrolateral toothed process arising from proximal bulbal sclerite, with small round sclerite between appendix and bulb. 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 barely visible in dissecting microscope. Male (variation) Tibia 1 in other male: 7.8. Female In general similar to male but eye triads on low humps and much closer together (distance PME–PME 220 µm); clypeus unmodiFed. Tibia 1 in 4 females : 5.9, 6.1, 6.1, 6.7. Epigynum weakly sclerotized plate with scape directed toward anterior, scape strongly folded and extensible, with distinctive widening in mid-section ( Fig. 77 ), distal part semitransparent; internal genitalia as in Fig. 78 . Natural history The spiders were found on the undersides of large leaves about 0.5–2 m above the ground.
