Genus Bandelopsis Frýda, Blodgett, and Stanley, 2003

Type species: Bandelopsis oregonensis Frýda, Blodgett, and Stanley, 2003 . Late Carnian– Early Norian , Wallowa Mountains (Oregon, USA) .

Remarks.—The following species are here tentatively ascribed to the genus Bandelopsis Frýda, Blodgett, and Stanley, 2003 on the basis of the general shape of the shell and ornament. Moreover in the specimen here assigned to Bandelopsis ? sp. the peristome, though partly preserved, is very similar to that of the type species, B. oregonensis Frýda, Blodgett, and Stanley, 2003 , i.e., thickened, slightly trumpet−shaped and with inner lip seemingly smooth and simple.

The species described below differ from B. oregonensis in having a larger number of spiral cords, and a slightly convex and inclined ramp. They differ from Nuetzelopsis Frýda, Blodgett, and Stanley, 2003 in having the ramp delimited by a distinct outer angulation and in the presence of granules or nodes at the intersection of the collabral ribs wih the spiral cords. The poor preservation of the material and the few available specimens suggest to leave open their generic assignment.

According to Bandel (2007), a simple inner lip distinguishes Bandelopsis from Fossariopsis Laube, 1869 . The latter has the inner lip with two teeth separated by a median depression which is a diagnostic character of the family Neritopsidae Gray, 1847 ( Bandel 2007, 2008). For this reason, Bandel (2007) excluded Bandelopsis from the Neritipsidae, but he did not suggest an alternative systematic placement for Frýda et al.’s (2003) genus. In fact, none of the combinations of characters established by him for identifying the neritimorph families corresponds to that exhibited by Bandelopsis .
