Genus Aleutijapelion gen nov.

urn:lsid:zoobank.org:act:22EAA94C-CE59-4729-86BF-39B49BF46D57

Diagnosis: Shell tall, moderately broad in profile; protoconch 2.5 whorls (nearly always eroded); whorls, seven or eight, rounded, without shoulder, suture fine, deeply impressed. Axial sculpture absent, spiral sculpture absent or faint, irregular; pillar deeply concave, base with constriction producing short extension of fasciole, lip projecting only slightly beyond pillar; final lip thickened, callus of anal sinus continuous with parietal callus; inner lip broad, not raised; canal short, broad. Radula, typical for this subfamily, rachidian tooth simple, acuspate.

Type species: Beringius aleuticus Dall, 1895 View in CoL (HD).

Remarks: This genus is similar to Metajapelion Chiba and Kosuge, 1980 (TS Tritonium (Buccinum) pericochlion Schrenck, 1862 , SD), but differs in 1) lacking the tabled shoulder, 2) lacking spiral sculpturing on the early whorls, and 3) spiral cords on base of body whorl. Goryachev, 1987: 35 subsequently designated Japelion perichochlion Schrenck, 1863 as the type species of Metajapelion (see Higo, Callomon and Goto 1999: 224).

Two species are recognized, Aleutijapelion aleuticus (Dall, 1895) , and Aleutijapelion mirandus n. sp. This genus is genetically close to Metajapelion , but we consider it distinct based on the before mentioned characters.
