Margareta's Frog

Odorrana is a captivating genus of true frogs predominantly found in East Asia and neighboring areas, particularly in fast-flowing mountain streams. These frogs are easily recognized by their pointed snouts, earning them the nickname "tip-nosed frogs."

The taxonomic history of Odorrana is rather convoluted. Initially, species from this genus were classified under other genera such as Rana, Amolops, Huia, and Eburana. However, in the early 21st century, molecular phylogenetic studies revealed that Odorrana, Amolops, and Huia are indeed distinct lineages within the Raninae subfamily. Notably, Odorrana appears to be closely related to Rana, potentially its nearest living relative. Although scientists have yet to definitively establish Odorrana as a separate genus, the supporting evidence is substantial.

These studies also identified several groups, or clades, within Odorrana. Some of these groups might even warrant classification as subgenera. For example, there is a basal group with species such as O. bacboensis, and another well-supported clade that includes species like O. margaretae. Another lineage features species such as O. absita and O. khalam, while a larger group encompasses species like O. amamiensis and O. nasica. Additionally, there is a possibility that the Phu Luang Cliff Frog might be reclassified under Odorrana.
