Etymology: Named in honour of our friend Dr Elizabeth Arias-Bohart who introduced Charles to Chile, organized permits and expeditions and encouraged our research.

Diagnosis: Males can be identified by their thin finger-like DTA directed retrolaterally ( Fig. 71D View Figure 71 ). Paracymbium present but not knob shaped, more flattened and inconspicuous ( Figs 71D View Figure 71 , 72C View Figure 72 ). Female with deep ‘M’-shaped atrium as in P. correcaminos with scalloped lateral margins, but P. ariasbohartae is distinct in that the fleshy bulge protruding out of the cavity is so large it bisects the cavity ( Fig. 71F View Figure 71 ); scape on posterior margin of bulge reaching past posterior margin of atrium; two slit-like openings in each cavity visible; lobes of the posterior margin folded anteriorly to form lateral margins, no deep groove present ( Fig. 71G, H View Figure 71 ) as in P. correcaminos ( Fig. 61F View Figure 61 ).

Description: Male: based in holotype. Markings as in Figure 70 View Figure 70 A-C, bright yellow anterolateral lines, faint median spots; sternum with yellow centre surrounded by thick, dark grey margin. Total length 4.76. Carapace length 1.33 times width. Chelicera length 2.14 times clypeus height. Sternum length 1.08 times width. Femur I 1.40 times carapace length. Leg formula 1423. Cymbium length 3.86 times length of bulb. Cheliceral promargin with five teeth and one denticle. Leg spination as follows: palp: femur d1-1-3, patella d1-1, tibia d0-1-0; leg I: femur d1-3-2-2, patella d1-1, tibia d1(r)-0-0, p0-1-1-0, v2-2-2, metatarsus p0-0-1, v2-2-2; leg II: femur d2-3-2-2, patella d1-1, tibia d1(r)-0-0, p0-1- 1-0, r0-1-1-0, v2-2-2, metatarsus d0-0-1, p0-1-1, r0-1-1, v2-2-2; leg III: femur d3-3-2-2, patella d1-1, tibia d1(r)-1- 0, p0-1-1-0, r0-1-1-0, v2-2-2, metatarsus d2-0-0, p0-1-2, r0-1-1, v2-2-2, tarsus r0-1, v0-2; leg IV: femur d1-2- 1(p)-2, patella d1-1, tibia d1(r)-0-1-0, p0-1-1-0, r0-1-1- 0, v2-2-2, metatarsus d2-0-1, p0-1-1, r0-1-1, v2-1(p)-2, tarsus r0-1, v0-3. Palp as in Figures 71 View Figure 71 and 72 View Figure 72 , with four tibial apophyses: VTA flattened mound with once concave and one convex side in ventral view ( Fig. 72B View Figure 72 ); RTA extended from tibia at about a 45° angle, tapered with a distal tooth directed apicad, slightly hooked ( Fig. 71B, E View Figure 71 ). LRTA bent, projecting ventrally with long tip, grey ( Figs 71D View Figure 71 , 72C View Figure 72 ). DTA long, slender, finger like, projected and pointed retroapically ( Figs 71E View Figure 71 , 72D View Figure 72 , far slenderer than DTA of P. torobayo or P. alopobre . Conductor ( Fig. 71B View Figure 71 ) more loosely twisted, ‘S’-shaped (curved over middle of bulb before terminating just distad of bulb as in P. correcaminos ). Embolus base shield like, smooth, entire anterior margin, without notch ( Figs 71B View Figure 71 , 72B View Figure 72 ). Embolus tip gradually tapered along posterior margin and curved to meet the tip of the conductor; embolus fine for the distal onethird of its length. Tegulum large, with dark margin and large median concavity. Paracymbium present but inconspicuous in ventral view, a subtle bulge on retroapical margin of cymbium ( Figs 71D View Figure 71 , 72C View Figure 72 ).

Leg measurements (right): leg I 13.80 (3.70, 4.55, 3.45, 2.10); leg II 11.95 (3.25, 3.70, 3.25, 1.75); leg III 11.10 (3.40, 3.1, 3.05, 1.55); leg IV 13.70 (3.50, 4.05, 4.25, 1.90); palp 7.20 (2.75, 2.05, –, 2.70).

D e s c r i p t i o n: F e m a l e: b a s e d o n p a r at y p e CASENT9026272, from Oncol Park. Markings as in Figure 70 View Figure 70 D-F. Total length 5.36. Carapace length 1.37 times width. Clypeus height 2.33 times AME diameter. ALE diameter 1.67 times AME diameter. Chelicera length 5.14 times clypeus height. Sternum length 1.13 times width. Femur I 1.02 times carapace length. Leg formula 4123. Cheliceral promargin with five teeth and one denticle. Leg spination as follows: palp: d1-1-3, patella d1-1, tibia d1-0-1, p1-0-0, tarsus d1(r)-0, p2-1- 1-0, r0-1-1-0, v1(r)-1(r)-2; leg I: femur d1-3-2-2, patella d1-1, d1(r)-0-0, p0-0-1-0, v2-2-2, metatarsus v2-2-3; leg II: femur d3-1(r)-3-2-2, patella d1-1, tibia d1(r)-0-0, p0-1- 1-0, r0-1-1-0, v2-2-2, metatarsus d0-0-2, p0-1-0, r0-1- 0, v2-2-3; leg III missing; leg IV: femur d1-1(p)-1-2-2, patella d1-1, tibia d1(r)-0-1-0, p0-1-1-0, r0-1-1-0, v2-2- 2, metatarsus d2-0-1, p0-1-1-1, r0-1-1-1, v2-2-2, tarsus r0-1, v0-3. Epigyne as in Figure 71F View Figure 71 , with ‘M’-shaped cavity bisected by a large, fleshy bulge with short, ovoid scape on posterior margin, scape reaching beyond posterior margin of cavity. Margins of cavity scalloped by a series of folds. Posterior margin continuous with lateral margin, no deep groove dividing posterior and lateral margins as in P. correcaminos . Centre of posterior margin with slightly darkened medial band. Slit-like copulatory openings visible inside cavity just adjacent to central bulge. Vulva ( Fig. 71G, H View Figure 71 ) resembles that of P. correcaminos , but can be distinguished by the elongated and more erect spermathecal stalks, extending beyond Base 2, and the slenderer profile of Base 1 in ventral view; left and right receptacles closer together than those of P. ariasbohartae . Bennett’s gland pore obscured by stalk in strict dorsal view. Atrium ventral wall with pronounced differences reflecting the morphology of the more elongated ventral bulge; midline of ventral wall with shallow and longer rift, compared to the ‘M’-shaped ridge and bulge of P. correcaminos . Ventral wall of P. ariasbohartae is shorter.

Leg measurements (right): leg I 9.90 (2.65, 3.35, 2.30, 1.60); leg II 8.45 (2.35, 2.75, 2.05, 1.30); leg III NA; leg IV 10.80 (2.90, 3.30, 3.10, 1.50); palp 3.60 (1.15, 1.25, –, 1.20).
