Source-derived summary

The cloud forest stream frog (Ptychohyla euthysanota) is a species of frog in the family Hylidae found in El Salvador, Guatemala, Mexico, and possibly Honduras. Its natural habitats are subtropical or tropical moist lowland forest, subtropical or tropical moist montane forest, and rivers. The cloud forest stream frog's lower elevation limit sits at 500 meters and its upper elevation limit is at 2,200 meters (approximately 1640 and 7218 feet respectively). The frog's current population trend is suspected to be decreasing due to the ongoing degradation in the quality and extent of its environment. It is common in Guatemala and Mexico, but the population status in Honduras and El Salvador are unknown. It is threatened by habitat loss. These frogs are semiaquatic, living both terrestrially and in inland freshwater.

Editorial summary

The public source identifies “Cloud forest stream frog” as species of amphibian. This brief keeps that definition visible, then builds a research path around Cloud, forest and stream.

Editorial reviewUseful for establishing the present vocabulary of the subject while preserving a route back to the evidence on which that vocabulary rests. The current lead gives the account dated anchors—1640—that can be checked directly. The selected authority fields contribute no independent date. Its value is orientation rather than verdict, with Cloud, forest and stream providing the first useful test.
Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “Cloud forest stream frog”, the useful work is to connect “species of amphibian” to the records capable of establishing context and consequence.

Evidence profile

Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Dec 6, 2025.

Critical limits

Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. 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.
