Kingdom Phylum Class Order Family

Scientific Name: Ecnomiohyla miliaria
Species Authority: (Cope, 1886)
Common Name(s):
English Cope's Brown Treefrog
Hyla immensa Taylor, 1952
Hyla miliaria (Cope, 1886)
Hypsiboas miliarius Cope, 1886
Plectrohyla miliaria (Cope, 1886)
Taxonomic Notes: This species was previously included in the genus Hyla but has recently been moved to the new genus Ecnomiohyla (Faivovich et al. 2005). We follow Duellman (2001) and Savage (2002) in assigning records from Colombia and Ecuador to Ecnomiohyla phantasmagoria.

Ecnomiohyla miliaria is currently a species complex which is under revision (Brian Kubicki pers. comm.).
