Minycardita sectilis Hoare & Plas, 2003

Minycardita sectilis: Hoare & Plas, 2003: 875 , fig. 1.9–14. Baiosoma sp.: Hoare & Plas, 2003: 873 –875, fig. 1.15–19.

Remarks. The two incomplete specimens of “ Baiosoma sp.” in Hoare & Plas (2003) are herein considered to be members of M. sectilis because they share all the distinguishing character states of Minycardita listed above, are roughly the same size, were found from the same locality as the other specimens of M. sectilis , and cannot be distinguished from the holotype and paratype of M. sectilis . One specimen ( Hoare & Plas 2003: fig. 1.16–18) appears to share with Baiosoma pala ( Hoare, Steinker, & Mapes, 1988), the type and only described species of that genus, a straight ventral surface just anterior to the carina, different from other specimens of Minycardita . However, this specimen has a number of character states found in Minycardita but not in Baiosoma , including a swollen body chamber, distinct radial ridges, small diameter rostrum, and smaller, shallower concavity around rostrum on posterior surface of main body chamber.
