Pseudaxine trachuri
species of worm

Pseudaxine trachuri is a species of monogenean, parasitic on the gills of a marine fish. It belongs to the family Gastrocotylidae.
Systematics
Pseudaxine trachuri was first described and illustrated based on specimens from the gills of the Atlantic horse mackerel Trachurus trachurus (Carangidae) (referred to as Caranx trachurus in the original description) off Genova, Italy. Pseudaxine trachuri was designated the type species of the genus.
Morphology
P. trachuri has the general morphology of all species of Pseudaxine, with a triangular body and an anterior extremity constricted at the level of buccal suckers in some species. The body comprises an anterior part which contains most organs and a posterior part called the haptor. The haptor is oblique and unilateral, and bears numerous clamps arranged in a single row. The clamps of the haptor attach the animal to the gill of the fish. The terminal lappet is present and bears two pairs of anchors. Also, two buccal suckers occur at the anterior extremity.
“Pseudaxine trachuri” enters the record as species of worm. Crown Archives preserves that source wording while asking what Pseudaxine, trachuri and species can confirm, complicate or overturn.
Why this record matters
“Pseudaxine trachuri” is worth following because a concise public description often conceals a longer documentary argument. Here, Pseudaxine, trachuri and species provides the most credible route into that argument.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Apr 20, 2026. The linked authority identifier is Q1914076. None of the 0 selected statements returned an explicit reference.
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.
