Aphantophryne nana
species of amphibian
Aphantophryne nana is a species of frog in the family Microhylidae. It is endemic to the Philippines and is known with certainty only from the island of Camiguin. It is unclear whether similar frogs from northeast Mindanao are referable to this species. It was
described as Oreophryne nana, but based on molecular data it was moved to Aphantophryne in 2017. Common names Camiguin cross frog, Camiguin narrow-mouthed frog, and volcano cross frog have been coined for the species.
Description
Aphantophryne nana are small, moderately slender-bodied frogs. Adult females in the type series measure 17–20 mm (0.7–0.8 in) in snout–vent length; no males were collected. The head is broader than it is long. The snout is short and bluntly round–pointed. The canthus rostralis is rounded.
This brief starts where responsible research should: with the source description of “Aphantophryne nana” as species of amphibian. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as species of amphibian. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Aug 8, 2026. The linked authority identifier is Q2276635. 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 lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
