Ctenophryne
genus of amphibians
Ctenophryne is a genus of microhylid frogs. They occur in southern Central America (Costa Rica, Panama) and South America. Their common names are egg frogs and Nelson frogs, the latter applying to species in the formerly recognized Nelsonophryne.
Taxonomy and systematics
As of 2017, Ctenophryne includes two other genera, Nelsonophryne and Melanophryne, in synonymy. The latter might represent valid genera, but molecular analyses could not resolve their relationships in a robust way. Placing Nelsonophryne and Melanophryne in the synonymy of Ctenophryne is an interim measure that avoids paraphyly, until new data might resolve the relationships. When Ctenophryne is defined this way, it is a monophyletic group that is the sister group to all
other gastrophrynines.
Description
Ctenophryne range from relatively small Ctenophryne barbatula (female size 26–27 mm (1.0–1.1 in) in snout–vent length) to moderately large Ctenophryne aterrima (female size to 67 mm (2.6 in)). The current definition of the genus is essentially based on molecular phylogenetics rather than morphology.
The public source identifies “Ctenophryne” as genus of amphibians. This brief keeps that definition visible, then builds a research path around Ctenophryne, genus and amphibians.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Ctenophryne”, the useful work is to connect “genus of amphibians” to the records capable of establishing context and consequence.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Dec 14, 2024. The linked authority identifier is Q2587666. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2017.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
