Diagnosis. Distinguished from similar known congeners ( C. djavani  , C. exigua  ) by details of male pedipalp ( Figs 689–691View FIGURES689–695; long tibia; procursus with subdistal prolateral branch), by armature of male chelicerae ( Fig. 692View FIGURES689–695; distinctive arrangement and sizes of two pairs of small frontal apophyses), by simple epigynum without pocket, with whitish median area at posterior margin of anterior plate ( Figs 694View FIGURES689–695, 715View FIGURES 711–720), and by internal female genitalia ( Figs 695View FIGURES689–695, 716View FIGURES 711–720; very large elongated pore-plates, parallel to each other).

Etymology. The specific name refers to the rapid running of this species (Latin agilis  = quick, swift); adjective.

Description. Male (holotype)

MEASUREMENTS. Total body length 2.0, carapace width 0.95. Distance PME-PME 80 µm, diameter PME 60 µm, distance PME-ALE 50 µm, distance AME-AME 25 µm, diameter AME 25 µm. Sternum width/length: 0.60/ 0.50. Leg 1: 12.4 (2.8 + 0.3 + 3.0 + 5.2 + 1.1), tibia 2: 1.9, tibia 3: 1.4, tibia 4: 1.7; tibia 1 L/d: 40. Femora 1–4 width (at half length): 0.19, 0.20, 0.20, 0.20.

COLOR (in ethanol). Prosoma and legs ochre, legs without dark rings, tips of tibiae whitish; abdomen pale gray, with large yellowish mark in hear area, light brown plate in front of gonopore, yellowish plate in front of spinnerets.

BODY. Habitus as in Figs 670–671View FIGURES665–676; ocular area barely raised; carapace with deep median furrow; clypeus unmodified; sternum unmodified.

CHELICERAE. As in Fig. 692View FIGURES689–695; with two pairs of small frontal apophyses; proximal pair with one uniquely curved modified hair on each apophysis.

PALPS. As in Figs 689–690View FIGURES689–695; coxa with large retrolateral apophysis; trochanter with small ventral process; femur with retrolatero-ventral process proximally; tibia very long; tarsus with prolatero-dorsal process; procursus weakly curved, with subdistal prolateral branch ( Fig. 691View FIGURES689–695); genital bulb large, with straight pointed apophysis and large, mostly membranous dorsal protrusion.

LEGS. Densely covered with regular short hairs, without spines and curved hairs, few vertical hairs; retrolateral trichobothrium on tibia 1 at 12%; prolateral trichobothrium present on tibia 1; tarsus 1 with ~25 pseudosegments, distally fairly distinct.

Male (variation). Tibia 1 in nine other males: 2.5–3.1 (mean 2.9); abdomen in some specimens with dark bluish internal marks dorsally and laterally.

Female. In general similar to male ( Fig. 672View FIGURES665–676) but abdomen without yellowish mark in heart area. Tibia 1 in 19 females from near Cachoeira da Gruta and Reserva Biológica de Saltinho: 2.2–2.5 (mean 2.3); in female from Alto da Serra: 2.8. Epigynum as in Figs 694View FIGURES689–695, 715View FIGURES 711–720; anterior epigynal plate simple, semicircular, without pocket and processes, weakly protruding, with distinctive whitish area at posterior margin; posterior plate narrow. Internal genitalia as in Figs 695View FIGURES689–695, 716View FIGURES 711–720, with pair of large elongated pore-plates lying parallel to each other.

Natural history. This species was abundant in dead bamboo sheaths on the ground at the forest edge and in regular leaf litter in the forest. During about 1 hour of searching of 1m 2 at Cachoeira da Gruta, about eight adult specimens were found, together with several specimens of the syntopic C. bispina  . In contrast to C. bispina  , this species lived higher in the leaf litter and ran rapidly when disturbed. Some females had large genital plugs.

Distribution. Known from three localities in Pernambuco state ( Brazil) ( Fig. 743View FIGURE 743).
