| Name | Westheide, W (1982). Microphthalmus hamosus sp.n. (Polychaeta, Hesionidae)—an Example of Evolution Leading from the Interstitial Fauna to a Macrofaunal lnterspecific Relationship. Zoologica Scripta 11 (3), 189–193. | ||||||

| Note | Microphthalmus hamosus sp.n. is described from Florida and North Carolina, USA. Striking characters as body shape, parapod construction, setation and shape of the anal plate can be referred to a close interspecific relationship with a macrofauna species: one specimen was found on Sipunculus nudus. The phylogenetic-systematic position of the new species within the genus is discussed. The speciation process leading to a niche outside the interstitial biotope included a secondary increase in body size and number of segments. Dollo's law is applicable on the sctation: setae which have been lost in the previous adaptation to interstitial life do not reappear. | ||||||
