Hogsback frog
species of amphibian

The Hogsback frog (Anhydrophryne rattrayi), or Rattray's forest frog, is a species of frog in the family Pyxicephalidae. It is one of three species within the genus Anhydrophryne. It is endemic to the Eastern Cape province of South Africa.
Discovery
This frog was initially discovered by Dr. George Rattray in the Hogsback Mountain region of the Eastern Cape, South Africa, and was described as a new species by John Hewitt in 1919.
Distribution and habitat
The frog is found in the Amotola (where the type locality, Hogsback is located), Katberg and Keiskammahoek mountains. Its habitat is the floor of forests near the forest edge at an altitude greater than 1100 m. It is particularly associated with the forest–grassland ecotone.
Biology
These small frogs are light-grey to dark-brown (sometimes coppery) in colour. The adult often has a thin pale line over its head and back, with two darker bands along either side.
The public source identifies “Hogsback frog” as species of amphibian. This brief keeps that definition visible, then builds a research path around Hogsback, frog and species.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Hogsback frog”, the useful work is to connect “species of amphibian” to the records capable of establishing context and consequence.
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 20, 2026. The linked authority identifier is Q2704336. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1919 and 1100.
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
