Cephalodella megalocephala (Glascott, 1893) 		Valid Name:
There is no data to display.
Parent taxa:             Genus / Family / Order / Superorder / Subclass / Class
Cephalodella: Notommatidae: Ploima: Pseudotrocha: Monogononta: Eurotatoria 		Taxonomic / nomenclatural notes:
• ?"Genus? species?" after De Smet (1989) [Ref.14236].
• Trophi morphology, bendable toes, and swimming behavior strongly deviate from what is known of other members of the genus; the assignment of C. megalocephala to genus Cephalodella requires reconsideration!
