Type material.

Holotype male from Colombia, Meta, Villavicencio, Bosque de Bavaria, 4.18089N, 73.64800W, 570 m, 7-X-2005, col. HJ Salazar (ICN-Ar 1404).

Diagnosis.

Anisaspis camarita sp. n. differs from A. tuberculata by the absence of a spine on dorsal tarsi distally, longer spinnerets (PLS) with apical segment digitiform (domed in A. tuberculata ) (Figure 1A, B) and AME on a super-tubercle (another higher tubercle on the ocular tubercle, Figure 1D).

Description.

Holotype male (ICN-Ar 1404) (Figure 1): total length 12.6; carapace length 6.0, width 6.5; abdomen length 5.8, width 3.4; chelicerae length 2.8. Color (in alcohol): body with soil particles encrusted; carapace, chelicerae, coxa, trochanter and femur dark reddish 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 strongly arched, separated from thoracic region by transverse shallow fovea, straight, width 1.1 (Figure 1A). Eyes and ocular tubercle: tubercle length 1.0, width 1.0, very elevated (height 0.8) and forwardly directed, with few stout setae. AME on a supertubercle (another higher tubercle on the ocular tubercle, Figure 1D). Clypeus absent. Anterior eye row slightly procurved, posterior recurved. Ocular sizes and interdistances: AME 0.25, ALE 0.30, PME 0.23, PLE 0.28, AME-AME 0.15, AME-ALE 0.05, PME-PME 0.48, PME-PLE 0.05, ALE-PLE 0.08, AME-PME 0.10, ALE-ALE 0.65, PLE-PLE 0.70. Chelicerae: short sparse bristles on dorsal and lateral areas, long fine bristles on ventral and anterior area. Rastellun absent. Cheliceral furrow with two rows of teeth well-developed, 12 and 9 teeth on promargin and retromargin, respectively. Fang long. Labium: length 0.7, width 0.9, with 77 cuspules on anterior edge (Figure 1C). Labio-sternal groove narrower in the middle than laterally. Maxillae longer than wide, with the anterior prolateral lobe very elongated, conical (Figure 1C); with 75/78 rounded cuspules spaced, largely spread over prolatero-ventral border from the inner edge to anterior lobe. Lyra absent. Sternum: length 2.5, width 3.4; three pairs of sigillae, anterior and median subcircular, posterior sigillae oval, all submarginal. Anterior half of sternum elevated (Figure 1C).

Legs: cuticle with soil particles encrusted. Leg and palpal segments measurements provided in Table 1. Leg I clearly thicker than the others. Bristles, plumose and thorn-like setae and spines evident. Trichobothria: filiform, on central 2/3 of tarsi, palp 5, leg I 8, II 7, III 6, IV 8; on distal 1/4 of metatarsi, legs I-III 4, IV 5; and on proximal 1/3 of tibiae, palp two rows of 3 each, legs I-III two rows of 4 each, IV two rows of 4 and 1 respectively. Scopula absent. Pseudoscopula weak and divided by conical longer setae, only present on distal tarsi I and II; tarsi III and IV with few sparse pseudoscopula setae. Claw tufts absent. Tarsal claws: ITC absent on all legs but a very small tooth present on right leg I in the same position of ITC; STC with one medial tooth on all legs. Tibial apophysis absent. Spination: principally thorn-like setae on all segments. Spines: palp and legs I-II 0; leg III, fe 0, pa 0, ti 0, me 1pd, 3v, ta 1p; leg IV, fe 0, pa 0, ti 0, me 2v, ta 1p.

Palp: cymbium with two unequal lobes separated by a sclerotized groove; tibia with shallow distoventral groove. Palpal bulb pyriform elongated; embolus curved, long, tapering to the apex, apex wide; a triangular translucent tooth on the subapical region, close to the apex (Figure 1E, F).

Abdomen: with four longitudinal dorsal rows of seven small tubercles, each emitting from its summit a plumose, bacilliform seta; lateral area finely tuberculate, with smaller plumose setae (Figure 1A). Book lung apertures projected, oval, sclerotized (Figure 1B). Spinnerets: PMS absent; PLS length 2.8, apical segment digitiform. Basal segment of PLS divided in two unequal cuticle plates (Figure 1B).

Female. Unknown.

Distribution.

Only known from its type locality, in the foothills of the Eastern Cordillera of Colombian Andes (at 570 m altitude), Meta Department, Bavaria forest (Figure 10).

Etymology.

The specific epithet camarita is a noun in apposition which means friend, in the colloquial way of the Llanos Region of Colombia, where this species is distributed.
