Charadrahyla

Charadrahyla is a group of frogs in the family Hylidae. They live in southern Mexico. The name of this genus comes from the Greek word "charadra" ("ravine") and "Hyla". Accordingly, common name ravine treefrogs has been coined for the genus.
Taxonomy and systematics.
Scientists made this genus in 2005 after looking closely at all the frogs in Hylidae. The frogs in "Charadrahyla" are those that used to be in the "Hyla taeniopus" group as defined by in 1970. The genus was originally made using molecular markers and no morphological synapomorphies, meaning that scientists only used the frogs' genes to tell whether they should be in this group. They did not use what the frogs looked like or how their bodies worked. The closet related group to "Charadrahyla" is the genus "Megastomatohyla".
Five of the frogs in this genus were in the genus "Hyla" before 2005. Since then, scientists discovered two species of frogs for the first time, and placed them in "Charadrahyla" too. Another two were moved into "Charadrahyla" from "Exerodonta" in 2018 after scientists studied their DNA.
Description.
The frogs in "Charadrahyla" are large for frogs. They lay eggs in streams in cloud forests and humid pine-oak forests of central and southern Mexico. Most of the male frogs in this genus are long from nose to rear end and females . But the former "Exerodonta" species, "Charadrahyla juanitae" and "Charadrahyla pinorum", are much smaller, with males and females . Most species have a brownish skin on their backs with large spots (exception is "Charadrahyla altipotens").
Species.
As of 2019, there were ten species in this genus:
