Archigetes (flatworm)

The genus Archigetes Leuckart, 1878 is unique among all tapeworms in that its species can mature in invertebrate hosts (Oligochaeta), in contrast to all other cestodes which have a vertebrate host. All five species were described as plerocercoids in oligochaetes, but two of them were also described as adults in cypriniform fishes.
