The first known genus of developayellids,
Developayella, was described in 1995. Due to many similarities shared with
opalinids and
heterokont algae, it was considered a member of the
stramenopiles, The concept of 'bigyromonad' was later expanded to include the class
Pirsonea, another group of phagotrophic stramenopiles. In 2016, a second genus
Develorapax was described, and the class
Developea was created to accommodate both genera. In 2018, Cavalier-Smith validated the order- and family-level names for this group under
zoological nomenclature:
Developayellida and
Developayellidae, respectively. The group was further expanded in 2020 and 2022 with the description of four new genera:
Mediocremonas,
Develocauda,
Develocanicus and
Cubaremonas. == References ==
