Palirhoeus
genus of insects

Palirhoeus is a monospecific genus of beetle found on islands in the Sub-Antarctic Indian Ocean.
Taxonomy
Palirhoeus eatoni is the only species within the genus Palirhoeus. This weevil species was described in 1876 by the British entomologist C. O. Waterhouse who placed it in the genus Ectemnorrhinus. In 1971, Chilean-New Zealand entomologist Guillermo Kuschel created the monospecific genus Palirhoeus.
Description
Palirhoeus eatoni is a weevil in the tribe Ectemnorhinini with seven larval instars. Adult females are on average larger (4.4 mm) than males (3.9mm). Adults are black or dark brown with a slight metallic sheen. Thorax has keel-like ridge.
Biology
Palirhoeus eatoni lives on the shoreline (in the littoral zone), where it feeds on marine algae and lichens. The species is tolerant of cold but cannot survive freezing.
The public source identifies “Palirhoeus” as genus of insects. This brief keeps that definition visible, then builds a research path around Palirhoeus, genus and insects.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Palirhoeus”, the useful work is to connect “genus of insects” 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 Apr 13, 2026. The linked authority identifier is Q21219047. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1876 and 1971.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. 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
Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
