Diagnosis
ReferenceDiagnosis
L. Anelli et al. 2009Similar to Pyramus Dana, 1847 and Jacquesia Mendes, 1944, medium sized, stout shelled megadesmid, nearly oval in shape; right valve with one discrete but defined blunt tooth anterior to beak, resulting from a rising fold of the ventral margin of the hinge plate; immediately below the beak, a well marked depression separates the anterior blunt tooth from a possible small second tooth; externally, a discrete sharp to rounded carina runs from umbonal region to the posterior dorsal angle delimiting a respiratory margin. Vestigial punctae are poorly preserved in the posterior and anterior external regions of shell.
