Panjange dinagat Huber sp. nov.

urn:lsid:zoobank.org:act:A711003E-5B76-4450-B9EE-C618A2200483

Figs 11–13, 74–78

Diagnosis

Easily distinguished from most known relatives (except Pa. marilog Huber sp. nov.) by complex male palpal trochanter apophysis (Fig. 75), and by widening of epigynal scape in mid-section (Fig. 77); from Pa. marilog Huber sp. nov. by male pedipalp (Figs 74–75; relatively wider tibia; shorter whitish elongation of tarsus; different shapes of procursus and appendix; more slender embolus) and female genitalia (longer than wide; Fig. 77).

Etymology

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

Type material

PHILIPPINES: holotype Ƌ, in ZFMK (Ar 13015), Dinagat Island, near Libjo, Paragua Forest, “ site 1 ” (10.222°N, 125.553°E), 130 m a.s.l., forest at brook, on leaves, 20 Feb. 2014 (B.A. Huber, P.N. Banaag).

Other material examined

PHILIPPINES, Dinagat Island: 1 Ƌ, 3 ♀♀, 2 juvs in ZFMK (Ar 13016), same data as holotype; 1 ♀, 2 juvs in pure ethanol, in ZFMK (Phi 232), same data; 1 ♀ in ZFMK (Ar 13017), near Libjo, Paragua Forest, “ site 2 ” (10.241°N, 125.545°E), 240 m a.s.l., forest along brook, on leaf, 20 Feb. 2014 (B.A. Huber, P.N. Banaag).

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.

Distribution

Known from type locality on Dinagat Island only (Fig. 16).
