| Summary: | Subfamily Parancistrolepidinae Habe, 1972 Diagnosis: Shell with suture constricted; sculpture chiefly spiral; aperture short, lacking long anterior canal; siphonal notch U-shaped, base of lip projecting anteriorly in some genera. Early teleconch whorls dome shaped, apex not projecting. Operculum narrow to broad, convex, with terminal nucleus. Radula most species with the rachidian and lateral teeth each with three sharply pointed cusps. Remarks: Habe, 1972 proposed Parancistrolepidinae (as Parancistrolepisinae) as distinct from Ancistrolepidinae (as Ancistrolepisinae), based on differences in the radula and the operculum between Parancistrolepis kinoshitai (Kuroda, 1931) and Ancistrolepis grammatus (Dall, 1907), and the type of the genus, Ancistrolepis eucosmius (Dall, 1891). Although he used the name Ancistrolepisinae, and implied that the two previously mentioned species were included in it, no actual diagnosis of the subfamily was offered, only a distinction between the radula and opercula of the two. ... : Published as part of Mclean, James H. & Clark, Roger N., 2023, Seven new genera and thirty-four new species of buccinoid gastropods (Neogastropoda: Buccinidae) from the Aleutian Islands, Alaska, pp. 151-201 in Zootaxa 5351 (2) on page 155, DOI: 10.11646/zootaxa.5351.2.1, http://zenodo.org/record/8391375 ... |
