Description

Male (based on holotype; WAM T44137). Total length 8.32.

Colour in ethanol: Pars cephalica and chelicerae dark brown, pars thoracica lighter brown (Fig. 2a, 3a). Mottled dark brown pigmentation around AME, PLE, and ALE (Fig. 3e). Sternum pale orange-brown, with eight sigilla of darker orange-brown; maxillae dark orange-brown, darker mottled patches basally; labium dark orange-brown with two distinct darker patches on the basal lateral edges (Fig. 3f). Abdomen dorsally and ventrally pale grey; ventrally with pale yellow book lungs. Spinnerets pale cream, with white interconnecting segments (Fig. 3c, d). Legs bright orange-brown, more or less uniform in colour.

Carapace: 3.37 long and 3.89 wide; pars cephalica height 1.53; pars cephalica covers 0.62 of carapace length. Pars cephalica smooth with few granulations; with two distinct, rounded indentations posterior to AME (Fig. 3e). Pars thoracica with slight granulation, deep trench running longitudinally from fovea to posterior edge; two lateral indentations posteriorly, and a moderately shallow central posterior notch; lateral edges strongly recurved and undulating (Fig. 3a). Pars cephalica strongly elevated, highest point anteriorly (Fig. 3i). Chelicerae: 2.32 long; elongate, and broadly cylindrical; dorsally with fine granulations, and with strong, distinct, and regular dorsal-prolateral transverse ridges, beginning at the midpoint and extending to the apex (Fig. 3a). Sternum: ovoid, with sparse setae. Four pairs of sigilla, all lightly depressed, anterior pair small, and oval; second pair consisting of either a cluster of three small depressions and a larger one (left), or two small adjacent depressions (right); third pair around the same size as the cluster of the second pair and oval; fourth pair largest, ca. twice the size of the third pair, oval (Fig. 3b). Labiosternal junction fused (Fig. 3b). Eyes: OQ four times wider than long; anterior eyes slightly procurved; posterior eyes strongly recurved (Fig. 3e). Cheliceral furrow with row of nine strong pyramidal teeth prolaterally the apical teeth connected in a ridge; retrolateral edge of furrow with two small teeth basally, and with a cluster of five small teeth in the inter-furrow region (Fig. 3h). Maxillae: anteriorly with ca. 80–100 weakly developed cuspules (Fig. 3f). Labium: conical; anteriorly with ca. 25 weakly developed cuspules (Fig. 3f), with labio-sternal sigillae basally (Fig. 3b). Rastellum well pronounced, with five strong, conical spines (Fig. 3g). Around 15 setae forming a fringe over the base the fang of each chelicera and the rastellum.

Abdomen: 3.42 long and 3.47 wide; rounded oval; four spinnerets (Fig. 3c, d).

Legs: sparse, scattered brown-black setae on all surfaces. Leg spination: leg I: tibia rv11, v4, pl7 (spinules), d2; metatarsus rv6, v6, pl6, d2; tarsus rv5, v2, pl5, d2; leg II: tibia rv6, v6, pl5 (spinules), d0; metatarsus rv5, v10, pl5, d0; tarsus rv9, v5, pl8, d0; leg III: tibia rv4, v2, pl6, d7 (spinules); metatarsus rv3, v0, pl6, d10; tarsus rv5, v0, pl7, d5; leg IV: tibia r2, v9, pl6, d0; metatarsus rv3, v0, pl13, d3; tarsus rv11, v3, pl16, d4; patella I 16 spinules prolaterally (Fig. 3k); patella II with ca. 10 spines prolaterally (Fig. 3l); patella III with dense covering of c. 90–100 spinules on the dorsal, prolateral and retrolateral surfaces (Fig. 3m); patella IV eight small spinules retrolaterally, four prolaterally (Fig. 3n). Scopulose setae on tarsus I and II. Tarsi and metatarsi III, IV with scopulae along ventral surfaces (leg IV imaged, Fig. 3j). Leg measure­ments: Leg I: femur 2.61, patella 1.18, tibia 2.21, meta­tarsus 1.71, tarsus 1.28, total 8.99. Leg II: femur 2.73, patella 1.28, tibia 1.61, metatarsus 1.43, tarsus 1.10, total 8.15. Leg III: femur 3.05, patella 1.29, tibia 1.64, meta­tarsus 1.93, tarsus 1.80, total 9.71. Leg IV: femur 3.56, patella 1.23, tibia 2.32, metatarsus 2.05, tarsus 1.69, total 10.85. Formula: 4>3>1>2.

Pedipalp: length of femur 2.28, patella 1.17, tibia 2.14, tarsus 0.76; all segments with scattered setae, sparse dorsally and those of the tibia thickest and longest ventrally (Fig. 4a–c). Tibia not inflated, broader basally, 0.83 wide on the widest point from dorsal and prolateral view, 2.6 times the length than the width (Fig. 4a). Bulb roughly pyriform (Fig. 4a–c). Embolus elongate, curved and slightly sinuous apically, with an apical lamella (Fig. 4d).

Variation (n = 10). All material examined had pars cephalica and chelicerae dark brown, pars thoracica lighter brown. Colour of the dorsal surface of the abdomen varied from pale-grey to slate-grey. Total length: 6.31–8.50, mean 7.32. Number of maxillary cuspules: 45–65, mean 51.8; number of labial cuspules: 21–29, mean 23.8; number of spines on the rastellum: left and right 4–6, left mean 4.5, right mean 4.63. All material examined had a distinct medial groove in the pars thoracica. Number of spinules on the left patella (n = 7): Leg I 11–19, mean 14.86; Leg II 7–11, mean 9; Leg III ca. 70–100; Leg IV 12–22, mean 15.86.
