A search of the available literature revealed that no other ancistrolepine (fossil or extant) has such a wide and flat outer lip callus, although a few extant species can have a very thin, narrow ridge callus. A terminal “varix” is common in warm, shallow-marine gastropods, but is rare in polar and deep-marine habitats (

(p. 12, figs. 2A–2D) from the upper Eocene Rategian Formation at Podkagernaya Bay, northwestern Kamchakta. The Llajas Formation species is similar in its ovate-fusiform shell shape, approximately five rounded whorls, rounded base on last whorl, subtriangular to triangular spiral ribs, about seven spiral ribs (can be variously spaced) on last whorl, and interstitial ribs on last whorl of some specimens.

differs from this Kamchakta species by having a smaller size shell, fewer spiral ribs on the spire whorls, many fewer and much less closely spaced spiral ribs on the siphonal canal, and the presence of a terminal varix on the outer lip.
