Zoobank registration: urn: lsid: zoobank. org:act: CF82E029-6963-4245-8D81-271EB7E65F61.
Types: Holotype male from wet disturbed forest in Chile, X Región de Los Lagos, Osorno Province,
hills south of Maicolpue, elev. 75 m [S40.6179º, W73.7468º], collected January 26, 1986, N. I. Platnick and R.T. S ch u h, (CASENT 9 0 4 4 6 4 7) deposited in AMNH.
Etymology: Named after the popular Chilean style of serving meat dishes, ‘a lo pobre’. A noun in apposition.
Diagnosis: Males of this species can be identified solely by the DTA; in lateral view, the DTA appears thumb like (Figs 58C, 59C), much larger than in P. ariasbohartae (Fig. 71D) or P. torobayo (Fig. 55C), blunted and dark, projected dorsally, perpendicular to frontal plane; in apical view, the DTA appears to have two small lobes (Figs 58D, 59D).
Description: Male: based on holotype. Markings as in Figure 57A, B, two yellow anterolateral bands with one pair of median spots. Total length 5.03. Carapace length 1.27 times width. Clypeus height 2.5 times AME diameter. ALE diameter 2 times AME diameter. Chelicera length 5.2 times clypeus height. Sternum as long as wide. Femur I 1.41 times carapace length. Leg formula 1423. Cymbium length 2.21 times length of bulb. Cheliceral promargin with four teeth and one denticle. Leg spination as follows: palp: femur d1-1- 3, patella d1-1, tibia d0-1(r)-0, tarsus p0-0-1, r0-0-1; leg I: femur d1-1-1(r)-1(p)-2, patella d1-1, tibia d1(r)- 0-0, p0-0-1-0, v2-2-2, metatarsus p0-0-1, v2-2-2; leg

II: femur d1-2-1-1(r)-1(p)-2, patella d1-1, tibia d1(r)- 0-0, p0-1-1-0, r0-0-1-0, v2-2-2, metatarsus d0-0-1, p0-1-0, r0-1-1, v2-2-2; leg III: d1-1(p)-2-2-2, patella d1-1, tibia d1(r)-0-1-0, p0-1-0-1-0, r0-1-1-0, v2-2-2, metatarsus d2-0-2, p0-1-0, r-0-1-0, v2-2-2, tarsus r0-1; leg IV: femur d1-1-1(p)-1(r)-2, patella d1-1, tibia d1(r)-0-1-0, p0-1-0-1-0, r0-1-0-1-0, v2-2-2, metatarsus d2-0-2, p0-1-0, r0-1-0, v2-2-2, tarsus r0-1. Palp as in Figures 58 and 59, similar to P. faberi, with a few noticeable exceptions. DTA is a thumb-like blunted projection oriented straight back dorsally (Figs 58A, C, 59A), oriented dorsoapically in P. ariasbohartae or P. torobayo. RTA thicker, extending out more perpendicular to tibia with thicker apex, blunted, with darkened tooth-like point on anterior margin directed anteriorly (Figs 58B, D, 59B). Embolus base longer, reaching past midline of bulb, anterior margin smooth, not notched (Fig. 59B). Embolus, VTA and conductor like P. faberi. Paracymbium present, knob like (Fig. 59C).
Leg measurements (right): leg I 13.35 (3.50, 4.40, 3.50, 1.95); leg II 11.30 (3.10, 3.55, 2.95, 1.70); leg III 10.25 (2.85, 3.05, 3.00, 1.35); leg IV 13.30 (3.50, 3.95, 4.05, 1.80); palp 5.65 (2.10, 1.45, –, 2.10).
Distribution: Known only from the type locality in Osorno Province, X Región de los Lagos (Fig. 76C).
Other material examined: None.
