NOV . FIGS 57–59 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 436 E.

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.
