Hyla hallowellii
Hallowell's Tree Frog
Subgenus: Hyla
family: Hylidae
subfamily: Hylinae
Taxonomic Notes: Duellman et al. (Zootaxa 2016) treated two major clades as genera; AmphibiaWeb treats these two clades as subgenera(Hyla in the Old World; Dryophytes in the New World and East Asia), thus stabilizing traditional taxonomy.
