Hypsagoninae
subfamily of fishes
Hypsagoninae is a subfamily of marine ray-finned fishes belonging to the family Agonidae, part of the sculpin superfamily Cottoidea. These fishes are found in the North Pacific Ocean.
Taxonomy
Hypsagoninae was first proposed as a taxonomic grouping in 1861 by the American zoologist Theodore Gill. Some workers have regarded the genus Agonomalus as synonymous with Hypsagonus and place the two remaining genera in the subfamily Percidinae which was also named by Gill in 1897. However, most authorities recognise the three genera and place them in the subfamily Hypsagoninae. The 5th edition of Fishes of the World classifies the Hypsagoninae within the family Agonidae, part of the superfamily Cottoidea, the sculpins.
Genera
Hypsagoninae contains following 3 genera:
Agonomalus Guichenot, 1866
Hypsagonus Gill, 1861
Percis Scopoli, 1777
Characteristics
Hypsagoninae sculpins typically have deep, laterally compressed bodies with a terminal mouth which has nearly equal jaws, The rear edge of the orbit is convex. The bony plates on the body are arranged in groups and rows which are bot clearly distinct and do not have exact margins and are made up of plates that differ in size and shape. There are plates on the first dorsal fin and the pectoral fin and there is no enlarged plate on the snout. The first dorsal fin is supported by strong spines.
Begin with the source’s own compact description: “Hypsagoninae” is subfamily of fishes. The dossier treats that line as a proposition to test through Hypsagoninae, subfamily and fishes, not as a finished interpretation.
Why this record matters
The phrase “subfamily of fishes” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Jul 6, 2026. The linked authority identifier is Q15269602. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1861, 1897, 1866 and 1777.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. 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.
