Figs 1–2, 8–25, 40–42
Gen.n. Bor80 – Huber et al. 2015a: 73–74.
Diagnosis
Easily distinguished from H. niah gen. et sp. nov. (and from other putatively close relatives in the genera Khorata, Savarna, and Aetana) by two pairs of horns on male ocular area (Figs 10, 14, 15, 17), by extremely long apophysis on male palpal trochanter (longer than femur; Fig. 9), and by scape on epigynum (Fig. 40) less sclerotized than in H. niah gen. et sp. nov. and with Fne transversal folds.
Etymology
The species name is derived from the type locality; noun in apposition.
Type material
MALAYSIA-BORNEO: holotype, Ƌ, Sarawak, near Kapit, forest along river, 1.937– 1.944° N, 112.904– 112.910° E, 80–120 m a.s.l., 20 Jul. 2014 (B.A. Huber, S.B. Huber), ZFMK (Ar 15068).
Other material examined
MALAYSIA-BORNEO, Sarawak: 7 ƋƋ, 4 ♀♀, same data as holotype, ZFMK (Ar 15069–70; 6 ƋƋ, 3 ♀♀) and SMK (1 Ƌ, 1 ♀); 2 ♀♀, 4 juvs, same data, in pure ethanol, ZFMK (Bor 183).
Description
Male (holotype)
MEASUREMENTS. Total body length 2.4, carapace width 0.9. Leg 1: 24.5 (5.8 + 0.4 + 5.7 + 9.3 + 3.3), tibia 2: 3.4, tibia 3: 2.4, tibia 4: 3.1; tibia 1 L/d: 72. Distance PME-PME 500 µm, diameter PME 105 µm, distance PME-ALE 25 µm, no AME.
COLOR. Carapace pale ochre with large dark lateral marks and median mark posteriorly, dark median line, ocular area and clypeus dark brown. Sternum dark brown to black. Legs ochre to light brown, without dark rings. Abdomen ochre-grey with large dorsal and lateral marks; ventral side largely covered by large dark mark and smaller dark mark at spinnerets.
BODY. Habitus as in Fig. 1; ocular area highly modiFed (Figs 10, 14, 15, 17), with two pairs of large horns arising from near PME and PLE and pair of smaller processes arising from near ALE; each triad on short stalk directed toward lateral; carapace with distinct thoracic furrow; clypeus with small median process (Figs 15, 17); sternum wider than long (0.60/0.50), unmodiFed. Chelicerae as in Fig. 11, with pair of proximal lateral apophyses in rather frontal position and pair of small, distal apophyses near lamellae; without modiFed hairs.
PALPS. As in Figs 8–9, coxa with sclerotized protruding rim ventro-distally; trochanter with distinctive long retrolateral apophysis widening distally and provided with small teeth at tip (Fig. 16); femur large, without processes; patella unusually long; tibia long and slender. Procursus highly complex, apparently with several hinges between distinctive sclerites. Bulb simple, weakly sclerotized embolus with subdistal branch.
LEGS. With single ventral row of ~25 spines on femora 1; without curved hairs; with short vertical hairs in two dorsal rows on all femora and tibiae; retrolateral trichobothrium on tibia 1 at 6%; prolateral trichobothrium absent on tibia 1, present on other tibiae. Tarsus 1 pseudosegments indistinct, only distally ~15 visible in dissecting microscope.
Male (variation)
Tibia 1 in 7 other males: 5.6–5.9 (mean 5.7). Spines on femora variable in thickness and number (~20–30).
Female
In general similar to male (Fig. 2); ocular area unmodiFed, triads closer together (distance PME-PME 220 µm), not on stalks; clypeus unmodiFed; no spines on femora; fewer vertical hairs on femora and tibiae (but especially on tibiae also with higher than usual density). Tibia 1 in 4 females: 4.7, 4.8, 4.9, 4.9. Epigynum large dark plate, weakly sclerotized, slightly protruding and with many Fne transversal folds, especially in posterior half (Figs 13, 40, 41); with distinctive scape, pale whitish distally; internal genitalia as in Figs 12 and 42.
Natural history
The spiders were found in domed webs in small holes in the ground along a river in well-preserved forest.
Distribution
Known from type locality near Kapit only (Fig. 7).
