Etymology.
The specific name is a noun in apposition taken from the
type
locality, Otonga Biological Reserve.
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
).
