Original Description
Cephalis trilobate, with large subglobular [antecephalic] lobe, smaller globular [cephalic] lobe, and inflated-conical [postcephalic] lobe, lying in the same plane. [Antecephalic] lobe bears two slender cylindrical tubes, one directed apically and the other posteriorly. [Postcephalic] lobe bears a slender cylindrical tube directed anteriorly. Thorax subcylindrical, inflated, or ovate, often with somewhat constricted mouth. Shell surface smooth, perforated by numerous small circular or subcircular pores, irregularly arranged.

Length of cephalis plus thorax 90-125µm, of tubes 15-120µm. Maximum breadth of thorax 50-60µm. Distinguishing characters (rw): This species closely resembles A. disolenius Haeckel, from which it differs principally in bearing two tubes on the occipital lobe. It differs from A. trisolenius Haeckel in having a trilobate cephalis.

Etymology: [Probably from the Latin tritubus = three tubes]
