Diagnosis. Males differ from those of T. longbottomi sp. nov. in that the paracymbial spine is noticeably wider distally, with longer distal extension of plate ( Fig. 128b View FIGURE 128 ); also T. carnarvon sp. nov. has larger dark markings on the carapace ( Fig. 127d View FIGURE 127 ) but T. longbottomi sp. nov. has stronger dark spotting on the ventral femora. Females differ from those of T. longbottomi in the strong fang setae and ridge above them ( Fig. 128e, f View FIGURE 128 ).

Etymology. A noun in apposition taken from the type-locality.

Description Holotype male WAM 98/1625

Carapace 4.00 long, 2.69 wide. Abdomen 4.38, 1.88 wide. Total length 8.7.

Colour: carapace dark orange brown with brown markings: broad irregular lobulate marks around margins, two long sinuous bands on caput, lateral and posterior of fovea large irregular patches; chelicerae dark brown with orange brown ovoid area medially; eyes not “masked”; abdomen contracted away from cuticle; dorsal tongue-like scute for half length, ventrally pallid with brown marks; legs yellow brown with small brown areas ventrally on femora around spine bases and bands on distal femora; maxillae and labium red brown, sternum orange brown, coxae all yellow brown. Carapace: with light cover of large black feathery hairs on brown thoracic region; cuticle finely pustulose; lateral margins not serrate and without sharp ledge; shallow pre-foveal saddle; fovea short, deep, on ridge not plateau; striae indistinct, masked by pattern. Eyes: AME clearly largest; ALE about smallest. Chelicerae: robust, vertical; low, rounded, glabrous lobes anterior and posterior to fang base; dentition formula: 2R, 2P; fangs long, tips well behind maxillae; furrow almost vertical, long. Maxillae: curved rounded ridge sloping steeply retrolaterally, apex rounded, small tear-shaped basal groove. Labium wider than long with short lunate depressions at basilateral margins. Sternum widely cordate with intercoxal extension at I/II; low profile with cover of few long erect bristles and many short brown hairs. Legs: coxae with three long midventral bristles in line for width and dividing coxa; RCH absent; trochanters with wide, symmetrical V-shaped notch, deeper distally; intercoxal processes strong on retrolateral edge of I–IV; light cover of small brown feathery hairs; scopula weak on all tarsi; sparse in distal half of metatarsi I and II. Spines: some long but none overlapping; proventral on femur I very long. I: fe pv1p2d3r1; ti p2v2.2.2.2; me v2.2. II: fe pv1p2d3r1; ti p2v2.2.2.2; me p2v2.2. III: fe p3d3r2; ti p2d1r2v2.2.2; me p3r3v2.2.3. IV: fe p2d3r1; ti p2d1r2v2.2.3; me p3r3v2.2.3. Palp: fe p1d2; pa (bristles) p1d1.1; ti p2 basal, d1. Abdomen: dense cover of brown feathery hairs; dorsal scute narrow with jagged margins, for anterior half; genital scute sclerotised back over booklungs; tracheal scute wide, oval with wide distal ridge. Palp: tibia with light proventral depression; cymbium: almost symmetrical from above; lateral margins narrow, prolaterally with light bush of long bristles over distal half of bulb, anterior cone grooved to tip but gradual and shallow; retrobasally with rounded margin above which is truncate scooped paracymbial spine on raised mound; weak scopula dorsally for distal fifth; bulb short, subtegulum not evident laterally on either side; embolic portion with basal narrow, spiralled collar becoming rugose, long and lobular with wide apex set above it; spermatic duct traced back from embolus twists under bulb, recurves and diagonally folds through the retrobasal tegulum.

Allotype female WAM98 About WAM /1626. As ♂ except as follows:

Carapace 4.06 long, 3.19 wide. Abdomen 4.08 long, 2.50 wide. Total length, 13.4.

Colour: carapace like ♂ but background fawn with large white feathery hairs making markings bolder. Abdomen dorsally pallid gray with darker zones formed by large dark feathery hairs in medial foliate band and narrow chevrons forming paler pairs of ovoid patches; ventrally fawn. Abdominal dorsal scute small dark rectangular. Femora-metatarsi yellow brown with 2–3 irregular dark bands of black feathery hairs. Chelicerae: with distinct squared anterior lobe bearing 3–4 short thick curved spines. Fangs and grooves shorter. Legs: trochantera with shallow but distinct notches. Feathery hairs small on dorsal femora. Scopula denser on metatarsi and tarsi I, II. Spines: also with long proventral spine on fe I. I: fe pv1p2 d3r1; ti p2v2.2.2.2; me p1v2.2. II: fe pv1p2d3r1; ti p2v2.2.2.2; me p2v2.2. III: fe p3d3r2; pa d1; ti p2d1r2v2.2.1 me p3r3v2.2.2. IV: fe p2d3r1; pa d1w; ti p2d1r2v2.2.2; me p3r3 v2.2.3. Palp: fe p1d2; pa p1d1.1; ti p2 basal, d1; ta p2 basal r1 basal. Palpal claw: long, dentate. Abdomen: post-epigastric sclerites short, rounded, open; tracheal spiracle with distinct sclerotised and semicircular scute. Epigyne: a broad open plate with two wide round fossae basally ectally bordered by lunate ridge; internally, a wide funnel-shaped duct leads to base of large, long, roughly reniform spermatheca narrowing through transverse creases to back.
