Description
Shell with very numerous, fine, low ribs, most of which bifurcate, ventral muscle field poorly defined with a short, low septum, teeth solid, lacking dental cavities, cardinal process small, bilobate, dorsal median septum high, extending to midline, spiralium and jugum unknown. [Poorly represented and known, requires revision. When erected, Neocoelia was regarded as a close relative to Anoplothera and Kayseria, with its shape suggesting closer affinity to the former. In the absence of revision of this genus, Alvarez prefers to regard it tentatively as belonging to the Anoplothecidae, while Copper suggests a closer relationship with Kayseria, of which Neocoelia seems to be an early relative.]
