Panjange marilog Huber sp. nov.

urn:lsid:zoobank.org:act:0B086DBA-DB8C-4253-AB9C-E932F2697216

Figs 14–15, 79–89

Diagnosis

Easily distinguished from most known relatives (except Pa. dinagat Huber sp. nov.) by complex male palpal trochanter apophysis (Fig. 80), and by widening of epigynal scape in mid-section (Fig. 82); from Pa. dinagat Huber sp. nov. by male pedipalp (Figs 79–80; relatively more slender tibia; longer whitish elongation of tarsus; different shapes of procursus and appendix; wider embolus) and female genitalia (wider than long; Fig. 82).

Etymology

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

Description

Male (holotype)

MEASUREMENTS. Total body length 5.1, carapace width 1.2. Leg 1: 41.2 (9.6 + 0.5 + 9.7 + 19.1 + 2.3), tibia 2: 6.5, tibia 3: 3.8, tibia 4: 5.7; tibia 1 L/d: 97. Distance PME–PME 470 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. 14; ocular area raised, each triad on long stalk, with pointed curved process arising from near PME and directed toward anterior (Figs 81, 84, 87); 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 (Figs 84–85); sternum wider than long (0.70/0.60), unmodiFed.

CHELICERAE. As in Figs 81 and 84, with pair of simple, weakly sclerotized processes in rather frontal position directed toward median; without modiFed hairs; without stridulatory ridges.

PALPS. As in Figs 79–80; 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 indistinct prolateral hump; tibia very thick (tibia width ~60% of length); tarsus with whitish elongation with terminal capsulate tarsal organ (Fig. 89); procursus proximal part with 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 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 with> 30 pseudosegments, only distally fairly distinct.

Male (variation)

Tibia 1 in 10 other males: 9.2–10.4 (mean 9.6). Background color of abdomen with variable shades of reddish to light brown (Figs 14–15).

Female

In general similar to male but eye triads on low humps and much closer together (distance PME–PME 240 µm); clypeus unmodiFed. Tibia 1 in 4 females: 7.1, 7.3, 7.3, 7.5. Epigynum weakly sclerotized plate with scape directed toward anterior, scape strongly folded, apparently extensible, with distinctive widening in mid-section (Fig. 82), distal part semitransparent; internal genitalia as in Fig. 83.

Natural history

The spiders were found on the undersides of leaves about 0.5–1 m above the ground.

Distribution

Known from two localities on Mindanao Island (Fig. 16).
