Genus Puytoracia Bonnet, 1970
Diagnosis: Test ovoid, elongated, rather close to that of Trinema enchelys. Ventral side slightly flattened, dorsal surface domed. Pseudostome of the plagiostome type, with the opening in the plane of the ventral surface or in a very slightly oblique plane with respect to the latter. Pseudostome circular or slightly elliptical. In the latter case, the pseudostome's major axis is perpendicular to that of the test. The pseudostome is bordered by a row of about twenty subcircular, nested scales, each bearing a strong central rectilinear denticulation bordered by two denticles which are at the limit of visibility under a light microscope. The typical thorny chitinoid necklace of the genus Trinema seems to be lacking. Test consisting of siliceous, endogenous, hyaline, elliptic scales, separated, very rarely joined (and then without appreciable superposition). Free space occupied by a second series of much smaller scales and also elliptic. There may be a very slight overlap between small and large scales, but in general, the contact seems to be punctual. Colorless hyaline cement.
