Allocareproctus
genus of fishes

Allocareproctus is a genus of marine ray-finned fishes belonging to the family Liparidae, the snailfishes. These fish are found in the northern Pacific Ocean.
Taxonomy
Allocareproctus was first proposed as a monospecific genus in 1993 by the Russian ichthyologists Dmitry Leonidovich Pitruk and Vladimir Vladimirovich Fedorov with Careproctus jordani as its only species. C. jordani had been described in 1930 by Charles Victor Burke with its type locality in Sagami Bay in Japan. In 2006 James Wilder Orr and Morgan Scott Busby reviewed the genus, described 4 new species from the Aleutian Islands and confirmed the genus as a valid genus.
Etymology
Allocareproctus is made up of Careproctus, the original genus of A. jordani, prefixed with allo, which means "other", i.e. close to Careproctus.
Species
Allocareproctus has 5 species currently classified within it:
Allocareproctus jordani (Burke, 1930) (Cherry snailfish)
Allocareproctus kallaion J. W. Orr & Busby, 2006 (Combed snailfish)
Allocareproctus tanix J. W. Orr & Busby, 2006 (Peach snailfish)
Allocareproctus unangas J. W. Orr & Busby, 2006 (Goldeneye snailfish)
Allocareproctus ungak J. W. Orr & Busby, 2006 (Whiskered snailfish)
Characteristics
Allocareproctus is characterized by the first 4 to 8 rays of the dorsal fin having their tips free of the fin membrane and they have papillae associated with of the sensory system on the head. In the skull the symplectic bone extends to the central faces of the quadrate bone and the metapterygoid. The largest species is A. jordani which has a maximum published total length of 34 cm (13 in).

Why this record matters
A short description can identify a subject without explaining its stakes. For “Allocareproctus”, the useful work is to connect “genus of fishes” 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 May 17, 2026. The linked authority identifier is Q2300899. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1993, 1930 and 2006.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. 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.
