Taxonomy and phylogeny
History
The Maricola group was first proposed by Hallez in 1892. He recognized three families: Otoplanida, Procerodida and Bdellourida.[2] Two years later, in 1884, Hallez renamed these families as Otoplanidae, Procerodidae and Bdellouridae.[3] In 1906 Böhmig classified the Maricola in two families and five subfamilies: Procerodidae (Euprocerodinae, Cercyrinae, Micropharynginae) and Bdellouridae (Uteriporinae, Eubdellourinae). In 1909 Wilhelmi wrote a monograph on the group in which five families were described: Procerodidae, Uteriporidae, Cercyridae, Bdellouridae, Micropharyngidae.[4] Von Graff used the same classification in 1916.[5] In 1989 Sluys recognized the six present families on the basis of phylogenetic analyses of the whole group.[6] However, recent molecular studies do not recover the currently established families.[7]
