Atlantihyla

Atlantihyla is a genus of frogs in the family Hylidae.^[2][3] It is endemic to Central America, specifically to Honduras and Guatemala.^[2] The generic name refers to its distribution on the Atlantic side of the isthmus (from Atlantis+hyla).^[1] The members of the genus are known as stream frogs.

Taxonomy

The genus was established based on molecular data in a revision of the subfamily Hylinae by Julián Faivovich and colleagues in 2018. In order to obtain a monophyletic Ptychohyla, Faivovich and colleagues moved two former Ptychohyla species to Atlantihyla and four former Ptychohyla species to Quilticohyla. Atlantihyla has a sister group relationship to a poorly-supported clade that includes Bromeliohyla, Duellmanohyla, and Quilticohyla.^[1] A third Atlantihyla species was described in 2020.^[4]

Description

The only, tentative phenotypic synapomorphy of this genus is the presence of a well-defined ventrolateral white stripe. A vertical rostral keel is present.^[1] Males measure 30–41 mm (1.2–1.6 in) and females 31–46 mm (1.2–1.8 in) in snout–vent length.^[1][4] The tadpoles have large oral discs.^[1]

Species

There are currently three recognized species:^[2]

• Atlantihyla melissa Townsend, Herrera-B., Hofmann, Luque-Montes, Ross, Dudek, Krygeris, Duchamp, and Wilson, 2020^[4]
• Atlantihyla panchoi (Duellman and Campbell, 1982) – Guatemala stream frog
• Atlantihyla spinipollex (K. P. Schmidt, 1936) – Ceiba stream frog

The AmphibiaWeb lists this genus as monotypic, with Atlantihyla melissa as the sole species.^[3]
