Description

Eleutherodactylus dimidiatus reaches 45 mm in SVL in adult females, with the males being smaller. Digital discs are absent. There is no webbing between the toes. The vomerine teeth, behind the choanae, are in an abruptly curved series (Cope 1862; Ruiz 1987; Schwartz and Henderson 1985; Schwartz and Henderson 1991).

These frogs are brown to golden tan, sometimes with a mid-dorsal pale hairline. The dorsal color is bordered laterally by a wide black band that is the posterior extension of a black canthal band. A bold straight cream line extends from the nares to the forelimb insertion, which is margined above by the dark canthal line and below by a dark labial line. A large, black groin spot may be present. The concealed surfaces of thighs are sometimes pinkish or reddish. The venter is pearly white (Cope 1862; Ruiz 1987; Schwartz and Henderson 1985; Schwartz and Henderson 1991).

Eleutherodactylus dimidiatus is a member of the Eleutherodactylus dimidiatus group (subgenus Euhyas). Related species include Eleutherodactylus emiliae, E. maestrensis, and E. albipes (Heinicke et al. 2007).

The chromosome number is 30 (Bogart 1981).

Synonyms include Hylodes dimidiatus (Cope 1862).
