Paracymbium present but not knob shaped, more flattened and inconspicuous ( Figs 71D, 72C). Female with deep ‘M’-shaped atrium as in  P. correcaminoswith scalloped lateral margins, but  P. ariasbohartaeis distinct in that the fleshy bulge protruding out of the cavity is so large it bisects the cavity ( Fig. 71F); 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) as in  P. correcaminos( Fig. 61F).  Description: Male: based in holotype. Markings as in Figure 70A-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.

Palp as in Figures 71and 72, with four tibial apophyses: VTA flattened mound with once concave and one convex side in ventral view ( Fig. 72B); RTA extended from tibia at about a 45° angle, tapered with a distal tooth directed apicad, slightly hooked ( Fig. 71B, E). LRTA bent, projecting ventrally with long tip, grey ( Figs 71D, 72C). DTA long, slender, finger like, projected and pointed retroapically ( Figs 71E, 72D, far slenderer than DTA of  P. torobayoor  P. alopobre. Conductor ( Fig. 71B) 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, 72B). 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, 72C).   Figure 70.Habitus of  P. ariasbohartae sp. nov.A-C, male holotype from Oncol Park, CASENT9026272.

Epigyne as in Figure 71F, 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. Centreof posterior margin with slightly darkened medial band. Slit-like copulatory openings visible inside cavity just adjacent to central bulge. Vulva ( Fig. 71G, H) 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 inventral 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. ariasbohartaeis 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).  Distribution:Only known from the typelocality, Oncol Park ( Fig. 76C).  Other material examined:None. 4126400327 2007-01-10 CASENT E.
