Type material.

Holotype male from Colombia, Cundinamarca, Río Negro Province, Topaipí, 1377 m, 18-23-x-2012, col. M Medrano, A García, E Martínez (ICN-Ar 11439).

Diagnosis.

Stormtropis colima sp. n. differs from the other species of the genus by the presence of a tibial apophysis with shorter base and not so much separated from the tibia as in the other species (Figure 5D, E). Additionally, S. colima sp. n. differs from S. parvum sp. n. by the presence of a continuous row and more numerous cheliceral teeth on promargin (13-11) (7 in S. parvum sp. n.) and from S. paisa sp. n. by the absence of a sclerotized dark mark on proximal dorsal tibia, without a slight excavation.

In addition, S. colima sp. n. is larger (8.4 mm) and lives at lower elevation (1377m) than S. parvum sp. n. (6 mm; 2750 m) and S. paisa sp. n. (8.5 mm; 2400 m).

Description.

Holotype male (ICN-Ar 11439) (Figure 5): total length 8.4, carapace length 4.2, width 4.2; abdomen length 3.3, width 2.7; chelicerae length 1.7. Color (in alcohol): body with soil particles encrusted; carapace, chelicerae, coxa, trochanter and femur dark brown; abdomen dorsally and patella-tarsus brown. Carapace: glabrous, striae conspicuous, lateral margins with single line of curved setae mixed with disperse clubbed setae; caput arched, separated from thoracic region by transverse shallow fovea, straight, width 0.4 (Figure 5A). Eyes and ocular tubercle: tubercle length 0.6, width 0.7, very elevated (height 0.5) and forwardly directed, with few stout setae. Clypeus absent. Anterior eye row slightly procurved, posterior recurved. Ocular sizes and interdistances: AME 0.23, ALE 0.25, PME 0.15, PLE 0.18, AME-AME 0.08, AME-ALE 0.03, PME-PME 0.28, PME-PLE 0.03, ALE-PLE 0.05, AME-PME 0.03, ALE-ALE 0.38, PLE-PLE 0.45. Chelicerae: dorsal few plumose setae, short sparse bristles on dorsal and lateral areas, long fine bristles on ventral and anterior areas. Rastellum absent. Cheliceral furrow narrow with two rows of teeth, 13/11 teeth on promargin, and 8 teeth on retromargin. Fang long. Labium subquadrate, length 0.5, width 1.00, with 39 elongated cuspules on anterior edge (Figure 5C). Labio-sternal groove narrower in the middle than laterally. Maxillae longer than wide, with the anterior prolateral lobe very elongated, conical; with 42/44 elongated cuspules widely distributed throughout the prolateral half of the maxillae; field of cuspules wider proximally (Figure 5C). Sternum heart shaped, length 1.73, width 2.15; three pairs of sigillae, anterior and median subcircular, posterior sigillae oval, all marginal (Figure 5C).

Legs: cuticle with soil particles encrusted. Leg and palpal segments measurements provided in Table 5. Legs I slightly stouter than II–IV. Femur IV widened. Clubbed plumose and thorn-like setae. Trichobothria: filiform, on central 2/3 of tarsi, palp, and all legs 5; on distal 1/4 of metatarsi, all legs 3; and on proximal 1/3 of tibiae, palp and legs I–III two rows of 2 each, IV 4. Scopula absent, few and sparse pseudoscopula setae on tarsi I and II. Claw tufts absent. Tarsal claws: ITC absent from all legs; STC long, with one tooth on all legs. Tibial apophysis on leg I present: a short flattened branch on distal prolateral side, with spines on two parallel rows, 10 distal and 5 proximal (Figure 5D, E). Thorn-like setae mainly present on legs III and IV. Spines absent.

Palp: cymbium with two unequal lobes separated by a sclerotized groove; tibia with shallow distoventral groove. Palpal bulb pyriform elongated; embolus curved, very long, tapering to the apex, apex wide; a triangular translucent tooth on subapical region, close to apex (Figure 5F, G).

Abdomen: oval, with small clubbed setae; lateral and dorsal areas finely tuberculate, with small plumose clubbed setae, principally on posterior area (Figure 5A). Book lung apertures projected, oval, sclerotized (Figure 5B). Spinnerets: PMS length 0.3; PLS length 1.6, apical segment digitiform (Figure 5B).

Female: unknown.

Distribution.

Only known from its type locality, Topaipí in the Río Negro Province (Cundimarca), in the Eastern Cordillera of Colombian Andes, at 1300 m altitude (Figure 10).

Etymology.

The species epithet colima is a noun in apposition which means warrior in the extinct Muisca language. The Colimas were an indigenous tribe that inhabited in the central highlands of Colombia, where the species occurs.
