Diagnosis. Cruziohyla calcarifer is a moderate to large species of the genus Cruziohyla , attaining a maximum SVL in males of 56.4 mm to 80.5 mm, and 57 mm to 88.8 mm in females, distinguished by a combination of the following characters: (1) prominent dark brown ventral thigh markings present either side of the vent in both sexes; (2) small tympanum, diameter 40–60% that of the eye; (3) fingers and toes moderately webbed, approximately two-thirds: modal webbing formula (fingers): I 2—2 - II 1 +— 2 III 1 1/2— 2- IV; modal webbing formula (toes): I 1— 1 + II 1—2 III 1 +—3 IV 3—2 - V; (4) in life, upper surfaces uniform green, often having small white or pale blue spots; (5) in life, yellow-coloured spot on the posterior rim of the eye when open; (6) short black bars to lateral surfaces of the flanks; (7) colour of undersides, hands, feet, concealed surfaces of thighs and flanks, orange; (8) short sloping snout; (9) calcar on heel, often terminating in two dermal processes with one projecting inward and one projecting outward.

Variation. Variation is noted in the extent of the outward facing calcar found on the heel: in all specimens from Costa Rica and Panama this feature is large, extensive, and marked with dark pigmentation; in some specimens from Colombia and Ecuador the outward-facing calcar on the heel is highly reduced and more rounded.

Distribution: Highly restricted populations occurring in northwest Ecuador, western Colombia, Panama, southeastern Costa Rica ( Fig. 10 ). See discussion.
