Newly Discovered Real Species of Frog That Looks like Kermit the Frog

"A new species of glassfrog, genus Hyalinobatrachium (Anura: Centrolenidae), from the Caribbean foothills of Costa Rica" [pdf]

"Abstract

We describe a new glassfrog belonging to the genus Hyalinobatrachium from the tropical wet forests and premontane rain- forests of the Caribbean foothills of Costa Rica, at elevations between 400–800 m. The type locality is approximately 4km west of Santa Clara, ca. 400 m a.s.l. (N 10.219, W 83.949). This new taxon is distinguished by its morphological charac- teristics, distinct advertisement call, and genetic distance (COI mRNA). The new species can be distinguished from other species of the genus Hyalinobatrachium by the combination of the following characters: (1) snout truncate in dorsal and lateral views; (2) granular dorsal skin; (3) parietal and cardial peritonea transparent; (4) hand webbing formula III 2-–2+ IV; (5) in life having a uniform lime green dorsal surface that lacks any evident light or dark spots; (6) iris coloration sil- very-white with fine dark spots or reticulation; (7) advertisement call consisting of a single tonal long metallic whistle- like note with a duration of 0.40–0.55 s (average 0.501 s) and a dominant frequency of 3.35–3.44 kHz (average 3.39 kHz); (8) highly divergent DNA sequences for the mitochondrial gene COI from other analysed members of the genus Hyalino- batrachium, with 12.4% divergence from its closest known species, Hyalinobatrachium chirripoi.
