Diagnosis. Adult females of P. otonga sp. n. are distinguished from all species as follows: from P. elicioi, metatarsi with 5 (Figs 21–24) up to 7 trichobothria as opposed to two trichobothria in P. elicioi (Dupérré 2015a: figs 6, 7) and spermathecae with longitudinal fold (Fig. 11) absent in the latter (Fig. 10); from P. pristirana sp. n. by the absence of multi-layered thin seta (Figs 13, 14); present in the latter (Fig. 28); and by the spermathecae being acuminate, shorter (3x longer than wide) with tightly arranged vesicles (Fig. 11), not acuminate, longer (4x longer than wide) vesicles not so tightly arranged in the latter species (Fig. 12) and from P. florezi by the female spermathecae with a genital fold (Fig. 11), absent in the latter species (see Perafán et al., 2019, fig. 3D).

Description. Female (holotype). Total length: 19.62; carapace length: 9.25; carapace width: 9.09; abdomen length: 10.37. Carapace (live color): Dark brown, covered with soil and sand along midline and radiating lines; with short setae along midline and radiating lines (Fig. 13). Chelicerae: Dark brown, slightly encrusted with sand and soil; promargin 14 teeth, retromargin 13 teeth; fang furrow narrow without denticles (Fig. 15). Sternum: light yellow, with six oval sigilla; wider than long, flat (Fig. 15). Labium dark orange basally, light orange apically, without soil, trapezoidal with ~86 cuspules (Fig. 15); maxillae orange, without soil, with conical projection anteriorly and ~103 cuspules (Fig. 15). Eyes: Eight on tubercle; AME rounded, separated by diameter; LE rounded, touching, ALE–PLE equal; PME oval smallest, separated by four times their diameter; anterior almost straight, and posterior eye rows recurved (Fig. 14). Abdomen: Oval, heavily encrusted with soil and sand (Fig. 13); dorsally with numerous, none conspicuous tubercles each bearing a seta, ventrally covered with soil and sand below epigastric groove; book lung apertures without soil and sand, oval, well sclerotized. Spinnerets: PLS yellow orange, not encrusted with soil and sand; basal and medial segment squared, apical segment cylindrical; respectively 0.92/0.96/1.65; PMS small, yellow orange, not encrusted with soil and sand (Fig. 16). Legs: Dark brown slightly encrusted with soil and sand, with few enlarged setae; leg I femora slightly enlarged; leg formula 4123; leg I 23.21(7.14/3.54/6.01/4.00/2.43); II 18.84 (5.72/2.75/4.23/3.79/2.35); III 16.29 (4.96/1.86/3.28/3.89/2.3); IV 25.49 (7.04/2.76/6.42/6.11/3.16). Leg spination: palpal tarsi: 1 rlv 2 plv; leg I: metatarsi 17rlv 18 plv; tarsi 11rlv 11plv. Trichobothria: tibiae I–IV (9/11/11/10); metatarsi I–IV (7/6/6/7); tarsi (13/11/12/14); palpal tibia (9): palpal tarsus (8). Paired tarsal claws with one elongate tooth; ITC on leg I (Fig. 26), absent on legs II–IV. Genitalia: Internal genitalia with elongated spermathecae (3x longer than wide) straight, with longitudinal fold, acuminate apically, with numerous tightly lobed vesicles (Fig. 11).

Male. Unknown

Trichobothrial pattern variation (paratype) (tibiae I–IV (8/8/8/8); metatarsi I–IV (5/5/5/5); tarsi (10/9/9/9) (Figs 17-24); palpal tibia (7): palpal tarsus (8) (Fig. 25).
