Odorrana
Odorrana (commonly known as the odorous frog) is a genus of true frogs (Ranidae) from East Asia and surrounding regions. Many of these frogs inhabit fast-flowing mountain streams, and they typically have a remarkably pointed snout, as evidenced by common names like tip-nosed frog and scientific names like "nasica" or "nasutus" ("with a nose"). Systematics and taxonomy. "Odorrana" has a confusing taxonomic and systematic history. Most species placed here were initially placed in "Rana". Some were considered to belong in "Amolops" and "Huia" instead, and yet again others were separated as "Eburana". The most extreme proposal was  to merge "Odorrana" into "Huia". In the early 21st century, molecular phylogenetic studies established that the systematic confusion was due to widespread convergent evolution between "Amolops", "Huia" and "Odorrana", which actually represent quite distinct lineages of Raninae. This necessitated some taxonomic changes, especially affecting "Huia". It was also found that "Odorrana" is a rather close relative of "Rana" (which includes "Lithobates" nowadays) – possibly the most closely related living lineage. And while it is not completely certain that "Odorrana" is in fact a distinct genus, the available evidence points towards this being so. Initial studies have revealed what seems to be  several clades of "Odorrana", which are sometimes considered subgenera. But few species have had their DNA sequence data sampled, and that the convergent evolution is liable to obscure relationships if assessed by morphology alone: In addition, the Phu Luang Cliff Frog (presently "Huia aureola") might belong in "Odorrana" too.
