Etymology. The specific epithet is a patronym in honor of Dr. Andrew J. Penniman (U.S.A.), who studied the genus Scotinella and improved the knowledge of North American phrurolithids.
Diagnosis. The females of P. pennimani sp. nov. differ from P. eutypus by having two oval atria (Fig. 5A) and the dorsal scutum is long and wide (Fig. 2C), while P. eutypus has two slit-like atria (Gertsch & Davis 1940: fig. 27) and the dorsal scutum covers only the base of the opisthosoma. The females of P. pennimani sp. nov. differ from P. separatus by having two large atria, S1 ectal to the CD, FD arising from the posterior part of the S1 (Figs 5A–D), the carapace that is almost as wide as long, and the opisthosomal scutum that is wide and long (Fig. 2C), while in P. separatus there is only one small atrium, S1 lie posterior to the CD, FD arise from the anterior part of the S1 (Figs 1E–H), the carapace is slightly longer than wide, and the opisthosomal scutum is narrow and short (Figs 1A, C). The females of P. pennimani sp. nov. differ from P. talquian sp. nov. by having two shallow epigynal atria (Fig. 5A), with the CO visible in ventral view (Figs 5A, 5C, 6C), oval S1, and by the apparent absence of S2 (Fig. 5B), while in P. talquian sp. nov. the epigynal atria are deeper, with the CO not visible in ventral view (Figs 10A, 10C, 11C), the S1 are liver-shaped, and by the presence of small S2 (Figs 10B, 10D). The males of P. pennimani sp. nov. differ from P. talquian sp. nov. by having a conical RTA with its tip very slender (thread-like, Figs 3A, 4A), by the shape of the DTA, finger-like when seen dorsally (Fig. 4B), and by the C tip widened in ventral view (Fig. 3B), while in P. talquian sp. nov. the RTA is tapering but the tip is not thread-like (Figs 8A, 9A), DTA in dorsal view is S-shaped (Figs 9B), and the C is not noticeably widened distally (Fig. 8B).

Leg spination: femur I with 2 prolateral spines in distal half; tibia I with 6 pairs of ventral spines; metatarsus I with 4 proventral spines and 3 retroventral spines. Femur II with 1 prolateral spine in distal half; tibia II with 5 pairs of ventral spines; metatarsus II with 4 proventral spines and 3 retroventral spines. Femora without dorsal macrosetae. Tarsal claw pectinate, onychium with pair of dorsal tactile hairs (Fig. 6D). Tarsal organ capsulate, with oval opening (Figs 4C–F). Palpus: femur with one dorso-distal spine, with central, broad and shallow depression on ectal side, with cluster of setae on mesal side (Figs 3C–D) and inconspicuous ventral apophysis perceived as slight swelling between the setae and depression (Fig. 3C). RTA long and conical, with distal part thread-like, as seen retrolaterally (Figs 3A, 4A). DTA tapering in lateral view, with its tip blunt (Fig. 3A), finger-like, directed towards ectal side in dorsal view (Fig. 4B). Cb with few short and thick setae on dorsal side and longitudinal narrow area without setae in its basal half (Fig. 4B). T large, protruding ectally at its proximal side (Figs 3B, 4A). E, EBP and C similar in length (Figs 6A–B). C with its tip widened and covering tips of E and EBP in ventral view (Fig. 3B).

Legs measurements: I 3.77 (0.99, 0.38, 1.05, 0.93, 0.42), II 3.12 (0.83, 0.34, 0.76, 0.74, 0.45), III 2.77 (0.73, 0.31, 0.55, 0.73, 0.45), IV 3.87 (1.00, 0.34, 0.86, 1.06, 0.61). Leg formula and spination as in male. Tarsal claw, onychium and tarsal organ (Figs 4G–I) as in male. Palpus: as in female of P. separatus, except tibia with one dorsal and one prolateral spine in its basal half, with small claw with few teeth. Epigynum: with two shallow atria separated by less than diameter of an atrium, depth of each atrium greater at CO, which are visible in ventral view (Figs 5A, 5C, 6C); B membranous, somewhat kidney-shaped in ventral view (Figs 5C, 6C). In dorsal view, oval S1 lie ectal to CD; B anterior to CO and slightly larger than S1 (Figs 5B, 5D); CD tube-like, slightly curved (Figs 5B, 5D); FD arise from mesal-posterior part of S1 (Fig. 5B).
Variation. Males (n=5) total length 1.93–2.27; carapace 0.95–0.97 long, 0.86–0.91 wide. The male scutum ranges from occupying roughly 3/5 to 4/5 of opisthosoma length. Females (n=11) total length 2.20–2.73; carapace 0.96–1.06 long, 0.85–0.97 wide. In females, the scutum ranges from almost 1/2 to 2/3 of the opisthosoma. Sometimes the same specimen (male or female) have one more or one less macrosetae on some of the anterior femora or metatarsi or both, but the leg in the opposite side has the number of macrosetae noted in the holotype. Some females have up to three slender white cream chevrons and one caudal spot above the anal tubercle.
Habitat. This species was collected from leaf litter in a shade-grown coffee plantation (Coffea arabica L.); the trees that provide shade are mostly Inga spp.
Distribution. Known only from the type locality in Chiapas, México (Fig. 12).
