Type material.

Holotype female from Colombia, Valle del Cauca, km 16 road Cali-Buenaventura, 3.52519N, 76.61992W, 1800 m, 14-xii-2014, col. C Perafán (ICN-Ar 11437). Paratypes: three females with the same data (ICN-Ar 11438).

Diagnosis.

Females of Paratropis florezi sp. n. differ from those of all other species of Paratropis by having the abdominal tubercles not prominent (Figure 3A) and by the spermathecal receptacles with a long neck, with the base widened and apex narrow, ended in a fundus with several projected lobes (Figure 3D).

Description.

Female (ICN-Ar 11437) (Figure 3): total length 15.2, carapace length 7.0, width 6.7; abdomen length 7.2, width 5.6; chelicerae length 3.4. Color (in alcohol): body with soil particles encrusted; carapace and legs reddish dark brown, chelicerae dark brown, abdomen grayish brown (Figure 3A). Carapace: scarcely setose, lateral margins with single line of spiniform setae; striae conspicuous; caput arched, separated from thoracic region by transverse fovea, slightly procurved, width 1.3 (Figure 3A). Eyes and ocular tubercle: tubercle length 0.8, width 0.7, very elevated (height 0.8) and slightly forwardly directed, with few setae. Clypeus absent. Anterior eye row slightly procurved, posterior recurved. Ocular sizes and interdistances: AME 0.38, ALE 0.35, PME 0.18, PLE 0.33, AME-AME 0.10, AME-ALE 0.08, PME-PME 0.55, PME-PLE 0.05, ALE-PLE 0.10, AME-PME 0.05, ALE-ALE 0.80, PLE-PLE 0.83. Chelicerae: short sparse bristles on dorsal and lateral areas, long fine bristles on ventral and anterior area. Rastellum absent. Cheliceral furrow with two rows of teeth well-developed, 11/13 and 9/12 teeth on promargin and retromargin, respectively. Labium: sub-rectangular, length 1.0, width 1.8, with 120 cuspules on anterior edge (Figure 3C). Labio-sternal groove with two lateral mounds. Maxillae longer than wide, with the anterior prolateral lobe very elongated, conical (Figure 3C); with 80/71 cuspules spaced, largely spread over prolateral-ventral border from the inner edge to anterior lobe. Sternum: heart shaped length 2.9, width 3.8; three pairs of sigillae, anterior subcircular, median and posterior sigillae oval; anterior and median sigillae marginal, posterior submarginal. Anterior edge of sternum with a semicircular area slightly elevated (joined to labio-sternal groove) (Figure 3C).

Legs: cuticle with soil particles encrusted. Leg and palpal segments measurements provided in Table 3. Palp, tarsi swollen. Leg I, clearly thicker than the others. Bristles, thorn-like setae, and spines present. Trichobothria: filiform, on central 2/3 of tarsi, palp 9, leg I 12, II 11, III 9, IV 13; on distal 1/4 of metatarsi, leg I 5, II 4, III 5, IV5; on proximal 1/3 of tibiae, palp and leg I two rows of 4 each, II two groups of 4 and 5 respectively, III two groups of 4 each, IV 2r-5p-1d (proximal/distal). Scopula or pseudoscopula absent. Claw tufts absent. Tarsal claws: ITC present on leg I; STC with one curved tooth on all legs. Spination: principally thorn-like setae on all segments. Spines: palp fe 0, pa 0, ti 0, ta 1pv, 4rv; leg I fe 0, pa 0, ti 0, me 10v, 5pv, 7rv, ta 10pv, 10rv; leg II fe 0, pa 0, ti 0, me 4v, 1pd, 1pv, 1rv, ta 3rv; leg III fe 0, pa 0, ti 0, me 3v, 2pd, 2pv, 1rv, ta 1pv, 1rv; leg IV fe 0, pa 0, ti 0, me 3v, 2pv, ta 5pv.

Abdomen: with four longitudinal dorsal rows of seven small tubercles, each emitting from them a plumose, bacilliform seta. Book lung apertures projected, oval, sclerotized (Figure 3B). Two spermathecal receptacles with a long neck, with the base widened and apex narrow, ended in a fundus with several projected lobes (Figure 3D). Spinnerets: PMS length 0.6; PLS length 2.7, apical segment digitiform. Basal segment of PLS divided in two unequal cuticle plates (Figure 3B).

Male. Unknown.

Distribution.

Only known from its type locality, in the western Cordillera of Colombian Andes, Valle del Cauca Department, km 16 road Cali-Buenaventura, at 1800 m altitude (Figure 10).

Natural history.

The females of Paratropis florezi sp. n. live in shallow burrows that they dig in the substrate of the ravines of the road.

Etymology.

The species epithet is a noun in genitive, in honor of Dr Eduardo Flórez Daza (ICN), in recognition of his friendship, teachings, and vast contributions to Colombian arachnology.
