Neonemertea

Belongs within: Nemertea.Contains: Heteronemertea, Monostilifera. The Neonemertea is a clade of nemertean worms identified by molecular analysis (Thollesson & Norenburg 2003). It unites the clades Hoplonemertea, in which the eversible proboscis is armed by one or more stylets, and Pilidiophora, whose members possess a distinctive larval form called a pilidium. <==Neonemertea |–PilidiophoraTN03 | |–HeteronemerteaTN03 |… Continue reading Neonemertea

Nemertea

Belongs within: Eumetazoa.Contains: Neonemertea. The Nemertea, ribbon worms, are a phylum of mostly marine worms though there are also some freshwater and terrestrial species. Among the major features of the group is the presence of an eversible proboscis contained in an anterior chamber called the rhynchocoel. In basal members of the Nemertea, commonly classified in… Continue reading Nemertea

Amphiporidae

Belongs within: Monostilifera. The Amphiporidae are a family of nemertean worms traditionally distinguished by the presence in most species of numerous (three or more) pairs of eyes. The molecular phylogenetic analysis of Thollesson & Norenburg (2003) indicated that the traditional ‘Amphiporidae’ is paraphyletic with regard to taxa previously included in Emplectonematidae, Ototyphlonemertidae and Prosorhochmidae, as… Continue reading Amphiporidae

Monostilifera

Belongs within: Neonemertea.Contains: Amphiporidae. The Monostilifera is a clade of nemertean worms characterised by the possession of a proboscis armed by a single stylet (Thollesson & Norenburg 2003). <==Monostilifera [Mictosemia, Paramonostilifera] | i. s.: Cryptonemertes actinophila (Bürger 1904)G02 | AnnulonemertesC03 |–Cratenemertea [Cratenemertiformes]C03 | |–KorotkevitschiidaeC03 | | |–AchoronemertesC03 | | `–Korotkevitschia Friedrich 1968C03 | | `–K.… Continue reading Monostilifera
