Entobia cateniformis Bromley et D’Alessandro, 1984

Diagnosis: Entobian developed as an open camerate system, comprising long rows of cylindrical chambers forming an irregular maze through branching and anastomosis. Many chambers elongated, commonly T-, L- or crossshaped where rows intersect. Elsewhere, no fusion of chambers. Intercameral canals reduced to constrictions. Apertures small, irregularly distributed; apertural canals well developed. Ontogenetic phases A, B and C well developed, D reduced.
