Diagnosis. - "The autothecal apertural apparatus is well-developed,
complex, and highly variable. The ventral and dorsal apertural processes
either differ in shape, dimensions, or size relations, or are identical to
each other. A single or both processes display their lateral margins turned
outwards and expanding distally, often with characteretic lateral lobes."
(Mierzejewski 1978, pp.568-569).
