Craticula,-ae (s.f.I): a genus of Diatoms; (in Diatoms) craticula, a type of modified, polymorphic valve, together with heribaudii valves in the genus Craticula. Craticular valves possess a central rib with plates that extend transapically across the valve, but the ribs lack a consistent definite shape or pattern. Craticula valves lack a raphe system. Heribaudii valves have radial, punctate striae that appear to retain an equal distance between striae. Unlike the craticula valves, heribaudii valves possess a simple raphe system similar to vegetative valves.” from description of Craticula cuspidata [> Fuelling, L., and LaLiberte, G. (2011).
