Cheilotrema
genus of fishes
Cheilotrema is a genus of marine ray-finned fishes belonging to the family Sciaenidae, the drums and croakers. These fishes are found in the eastern Pacific Ocean.
Taxonomy
Cheilotrema was first proposed as a monospecific genus in 1861 by the Swiss naturalist and explorer Johann Jakob von Tschudi. Tschudi was describing a new species from Peru, Cheilotrema fasciatum, and created the new genus for it. Cheilotrema belongs to the family Sciaenidae in the order Acanthuriformes.
Etymology
Cheilotrema combines cheilos, meaning "lip", with trema, which means "pore", an allusion to the obvious pores on the upper lip of C. fasciatum.
Species
Cheilotrema has two recognised species classified within it:
Cheilotrema fasciatum Tschudi, 1864 (Arnillo drum, Burro)
Cheilotrema saturnum (Girard, 1858) (Black croaker)
Characteristics
Cheilotrema croakers have deep, oblong shaped bodies with a sloped head and pointed snout. The mouth is just below the snout and there are 5 pores on the chin but no barbels. The preoperculum may have either a serrated or smooth margin. The dorsal fin has a deep incision dividing it and there are 10 spines to the front of the incision and a single spine and between 24 and 28 soft rays to its rear.
The public source identifies “Cheilotrema” as genus of fishes. This brief keeps that definition visible, then builds a research path around Cheilotrema, genus and fishes.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Cheilotrema”, the useful work is to connect “genus of fishes” to the records capable of establishing context and consequence.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated May 18, 2026. The linked authority identifier is Q2962149. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1861, 1864 and 1858.
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.
