Developeans[2] or developayellids[3] are a group of predatory single-celled eukaryotes. They are classified as the family Developayellaceae[1] (or Developayellidae in zoological nomenclature), the only family in the order Developayellales[4] (or Developayellida in zoological nomenclature) which is in turn the sole order in the class Developea,[5] part of the stramenopiles. All known members consume bacteria as prey, except for the genus Develorapax , which consumes other eukaryotes.[6]
Taxonomy
[edit ]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,[7] a diverse group of protists distinguished by two unequally sized flagella, one of which has tripartite mastigonemes (hair-like structures).[8]
In 1997, Thomas Cavalier-Smith proposed Developayella as the evolutionary link between pseudofungi and opalinids, and described higher taxon ranks to accommodate this genus: family Developayellaceae, order Developayellales, and class Bigyromonadea, in the stramenopile phylum Bigyra.[9] The concept of 'bigyromonad' was later expanded to include the class Pirsonea, another group of phagotrophic stramenopiles.[10] [11]
In 2016, a second genus Develorapax was described, and the class Developea was created to accommodate both genera.[12] In 2018, Cavalier-Smith validated the order- and family-level names for this group under zoological nomenclature: Developayellida and Developayellidae, respectively.[11] The group was further expanded in 2020 and 2022 with the description of four new genera: Mediocremonas ,[13] Develocauda , Develocanicus and Cubaremonas .[6]
