Taxonomy
Holoaden is the type genus of subfamily Holoadeninae that was erected in 2008 and placed in family Strabomantidae, erected at the same time. Before that, it was in Brachycephalidae. However, later research has led the whole Strabomantidae, Holoadeninae included, to become included in Craugastoridae. This arrangement is not followed by all, and the AmphibiaWeb still keeps Holoadeninae, and consequently Holoaden, in Strabomantidae.
Description
Holoaden grow to 48 mm (1.9 in) snout–vent length at most. Head is narrower than the body. Differentiated tympanic membrane and tympanic annulus are absent. Dorsum is highly glandular. Venter is areolate.
