Paratropis carcosita new species

Figures 16–17, Map 1.

Type material. Female holotype from Santa Elena province, La Rinconada (–01°42’48’’, –80°47’48’’) 47 m, 11– 13.X.2013, R. Romo, ECFN 7236 (QCAZ) . Paratype: 1♀, same data as holotype, ECFN 7238 (QCAZ) .

Etymology. The specific epithet is non-Latin adjective (invariable) taken from the Spanish language meaning “dirty” in reference to the species covered with soil particles.

Diagnosis. Females most resemble those of P. kapak sp. nov. but are distinguished by spermathecae with rounded spermathecal heads (Fig. 17C, D), versus oval spermathecal heads in the latter species (Fig. 13C–E).

CEPHALOTHORAX: Carapace orange-brown covered with soil particles, caput arched; fovea, recurved (Fig. 17A). Chelicerae dark orange-brown covered with soil particles; promargin 16 teeth, retromargin 12 teeth. Labium sub-rectangular, 90 cuspules anteriorly (Fig. 17B). Maxillae longer than wide, anterior prolateral lobe elongated, conical; 46 cuspules spread over ventral surface; outer margin with 32 spinules (Fig. 17B). Sternum length 2.65; width: 3.33, oval, with three pairs of oval sigilla (Fig. 17B). EYES: Eight eyes on tubercle, height: 0.67; AME rounded 0.21; ALE 0.23; PME 0.12, PLE: 0.19; PME–PME 0.53. ABDOMEN: Dorsally dark gray, with beige patches strongly encrusted with soil particles, with 7 transversal rows of spatulate setae; laterally gray strongly encrusted with soil particles with fewer and smaller spatulate setae; ventrally beige with some soil particles, without spatulate setae (Fig. 16A, B). LEGS: Uniformly orange-brown partially covered with soil particles. Macrosetae ventrally on tibia III–IV, on metatarsi and tarsi II–IV. Spinules on leg I ventrally, tibia: 1–3, metatarsus: 21, tarsus: 10; tarsal scopula absent. Trichobothria: palpal tarsus: 8; tarsus I: 9, II: 9/10, III: 8, IV: 10; metatarsus I: 5, II: 4, III: 4, IV: 5/6. Legs measurements: I 15.78 (4.85/2.07/4.20/3.08/1.58); II 13.36 (4.14/1.76/3.03/2.79/1.64); III 11.24 (3.47/1.41/2.18/2.57/1.64); IV 17.35 (4.64/1.86/4.25/4.10/2.50); leg formula 4123. Tarsus I third claw present; tarsi II–IV without third claw; all paired claws with one tooth.
