Figs 52–53 View Figs 50–57 , 81–84 View Figs 81–84 , 93–95 View Figs 93–101 , 1034


Distinguished from known congeners by armature of male chelicerae ( Fig. 83 View Figs 81–84 ; distinctive pair of distal processes and pair of low frontal humps), by shape of procursus ( Fig. 82 View Figs 81–84 ; distinctive subdistal dorsal widening – arrow in Fig. 82 View Figs 81–84 ), by strongly banded legs ( Figs 52–53 View Figs 50–57 ; femora with 3–4 dark rings), and by external and internal female genitalia ( Figs 84 View Figs 81–84 , 93 View Figs 93–101 ): strong lateral sclerites, small median sclerite; pair of internal anterior pockets/folds; elongate transversal pore plates close together; note that female of C. merida Huber, 2000 is unknown.


The species name refers to the type locality; noun in apposition.

Type material

VENEZUELA – Miranda • ♂ holotype, ZFMK (Ar 21832), El Ávila National Park , near La Julia, ‘site 2’ (10.5037° N, 66.8107° W), 1060 m a.s.l., dry forest, 22–23 Feb. 2020 (B.A. Huber, O. Villarreal M.) GoogleMaps .

Other material examined

VENEZUELA – Miranda • 4 ♂♂, 5 ♀♀, ZFMK (Ar 21833), and 8 ♀♀, 7 juvs in pure ethanol, ZFMK (Ven20-179), same collection data as for holotype GoogleMaps .


Male (holotype)

MEASUREMENTS. Total body length 1.25, carapace width 0.60. Distance PME–PME 50 µm; diameter PME 60 µm; distance PME–ALE 30 µm; AME absent. Leg 1: 10.9 (2.8 +0.2+2.8 +4.3+ 0.8), tibia 2: 1.6, tibia 3: 1.1, tibia 4: 1.3; tibia 1 L/d: 56.

COLOR (in ethanol). Prosoma and legs pale ochre-yellow, carapace and clypeus medially darker, legs with indistinct dark rings on femora (three) and tibiae (two); abdomen pale gray, dorsally light brown with large dark marks.

BODY. Habitus as in Fig. 52 View Figs 50–57 . Ocular area moderately raised. Carapace with distinct thoracic groove. Clypeus unmodified but slightly more protruding than in female. Sternum wider than long (0.44/0.32), with pair of small but distinct anterior processes. Abdomen globular.

CHELICERAE. As in Fig. 83 View Figs 81–84 , with distinctive pair of distal processes overhanging fangs and pair of low, light frontal humps.

PALPS. As in Figs 81–82 View Figs 81–84 ; coxa with distinct retrolateral-ventral apophysis, trochanter barely modified, femur proximally with light retrolateral process, distally with small ventral process; procursus with distinctive subdistal dorsal widening (arrow in Fig. 82 View Figs 81–84 ); genital bulb with complex distal process.

LEGS. Without spines and curved hairs; with higher than usual density of vertical hairs on tibiae (apparently only dorsally); retrolateral trichobothrium of tibia 1 at 11%; prolateral trichobothrium absent on tibia 1; tarsus 1 with ~13 pseudosegments.

Male (variation)

Tibia 1 in five males (incl. holotype): 2.7–2.9 (mean 2.8). Female

In general similar to male ( Fig. 53 View Figs 50–57 ) but without humps on sternum, clypeus less protruding, few vertical hairs on leg tibiae, sternum anteriorly laterally light brown, rings on legs more distinct, femora with four rings. Tibia 1 in five females: 1.9–2.2 (mean 2.02). Epigynum ( Fig. 93 View Figs 93–101 ) barely protruding, anterior plate with strong lateral sclerites, medially whitish with small light brown sclerite; large light brown posterior plate. Internal genitalia ( Figs 84 View Figs 81–84 , 94–95 View Figs 93–101 ) with elongate transversal pore plates close together and pair of unsclerotized internal anterior pockets/folds (arrows in Fig. 84 View Figs 81–84 ); large median transparent receptacle.


Known from type locality only, in Venezuela , Miranda (Fig. 1034).

Natural history

Most specimens were collected in masses of dead leaves and other debris suspended among lianas and other vegetation ~ 1–2 m above the ground.
