Entobia ovula Bromley et D’Alessandro, 1984

Diagnosis: A camerate entobian composed in the mature stage of small chambers of globose to ovoid shape, greatly crowded, arranged in a boxwork. The chambers are separated from neighbours by a very short intercameral canal, usually reduced to a constriction. In phase C, the chambers are arranged in straight strings, forked at variable angles and anastomosed, giving rise to a network in one or two, poorly distinguishable tiers. A and B phases are reduced. Apertural canals distinct, tapering distally, or slightly inflated as a barrel. The openings are relatively small, numerous, rather regularly disposed, rarely fused.
