The flatworms, flat worms, Platyhelminthes, or platyhelminths (from the Greek πλατύ, ''platy'', meaning "flat" and ἕλμινς (root: ἑλμινθ-), ''helminth-'', meaning "worm") are a phylum of relatively simple bilaterian, unsegment ...

Taxonomy and phylogeny
History
The Maricola group was first proposed by
Hallez in 1892. He recognized three
families
Family (from la, familia) is a group of people related either by consanguinity (by recognized birth) or affinity (by marriage or other relationship). The purpose of the family is to maintain the well-being of its members and of society. Ideall ...
: Otoplanida, Procerodida and Bdellourida. Two years later, in 1884, Hallez renamed these families as Otoplanidae, Procerodidae and Bdellouridae. 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. Von Graff used the same classification in 1916. In 1989

recognized the six present families on the basis of
phylogenetic analyses of the whole group.
