Description:Bolitoglossa conanti has a standard length of approximately 46.7-48 mm. The head is narrow and there is a distinct groove below the eye that does not extend onto the lip. The labial protuberences are prominent especially in males. This species has many vomerine teeth. The snout is short. The eye does not protrude from the head when viewed from below in males. Limbs are slender and moderately long. The digits are expanded into subterminal pads. Webbing is moderate in forelimbs and hindlimbs. The tail is long, slightly compressed laterally and is constricted near the base (McCranie et al. 1993).

Diagnosis: B. conanti can be distinguished from its close relatives within the B. dunni group by its dorsal coloration patterns. Other members are Mahogany Red. The amount of webbing is used to also distinguish it from others in the group (McCranie et al. 1993)

Coloration:Coloration is variable. B. conanti has two color phases. One phase is a pale, longitudinal band from snout tip to the dorsal tail surface. The other has dark brown dorsal surfaces with gold spotting or blotching. The subcaudal surface is spotted with gold and sometimes silver on a tan to dark brown background (McCranie et al. 1993).

Variation:Coloration patterns vary between the two described phases with intermediate stages. The maxillary and vomerine tooth number is also somewhat variable (McCranie et al. 1993).

Females are more robust than males, lack mental glands and the eyes are not visible from the ventral view (McCranie et al. 1993).

B. conanti was first described by McCranie et. al. (1993).

It is named in honor of Roger Conant, for his contributions to the field of herpetology (McCranie et. al. 1993).

B. conanti is a member of the Bolitoglossa dunni group (McCranie et. al. 1993). It is also included in subgenus Magnadigita (Frost 2011; Wiens et. al 2007).
