There are not many synonyms for the scientific name Genus Hylactophryne, which refers to a group of frogs endemic to the high Andes of South America. However, Hylactophryne is sometimes grouped under the synonym Hypodactylus, which was another genus of Andean frogs until it was subsumed into Hylactophryne in the late 20th century. Within the Genus Hylactophryne, there are several recognized species, including Hylactophryne augusti, Hylactophryne baturitensis, and Hylactophryne bromeliaceae, among others. These species share certain physical and behavioral characteristics, such as small size, arboreal habits, and care of eggs and tadpoles by parent frogs, which are typical of Hylactophryne as a genus.
