Ikosipodus carolensis gen. et sp. n., an interstitial neotenic polychaete from North Carolina, U.S.A., and its phylogenetic relationships within Dorvilleidae
Ikosipodus carolensis gen. et sp.n. from shallow subtidal sands off the coast of North Carolina is described. The species shows conspicuous neotenic features. The sexes are separate and dimorphic. The juveniles resemble the adults greatly. A seminal receptacle in the male, of which the fine structure was investigated, is the first proof of direct sperm transmission in the Dorvilleidae. The new form has been classified into a tentative phylogenetic dendrogram of the dorvilleid genera
