    Marine relatives of terrestrial nemerteans: The genus Prosadenoporus Bürger, 1890 (Hoplonemertea) (1988)
    Springer
    Hydrobiologia 156 (1988), S. 75-86

    Notes: Abstract A diagnosis of the monostiliferous hoplonemertean genus Prosadenoporus is provided and the type-species, P. arenarius, is redescribed and illustrated from Malaysian material; this identification is related to Bürger's (1890) original description. The remaining four species can on present evidence neither be accepted as valid taxa nor regarded with certainty as synonymous with P. arenarius; they are accordingly designated as nomina dubia. A comparison between Prosadenoporus, Prosorhochmus and the group I genera of terrestrial nemerteans (Geonemertes, Pantinomemertes) indicates that they belong in the same family, Prosorhochmidae, and a definition of this family is given.

    Methods of classifying nemerteans: an assessment (1993)
    Springer
    Hydrobiologia 266 (1993), S. 89-101

    ISSN: 1573-5117
    Keywords: classification ; phenetics ; cladistics ; phyletics

    Topics: Biology
    Notes: Abstract Phenetic, cladistic and phyletic methods of classifying animals are discussed with particular reference to nemerteans. It is concluded that phenetic (numerical) taxonomy is particularly inapplicable to any group of invertebrates for which well defined character differences are relatively few, whilst both the phenetic and cladistic methods fail through their fundamental assumption that convergent evolution is a rare occurrence. Terrestrial and freshwater nemerteans especially demonstrate convergent evolution in many ways; cladistic classifications proposed for these animals are therefore untenable. Convergence is shown to be a common occurrence in other nemerteans also. It is concluded that because the traditional phyletic approach does not implicitly assume that resemblances between organisms are more likely to be due to common ancestry than to convergence, it is far more likely to reveal true evolutionary relationships between taxa.
