Taxonomy Rhizothrix Brady & Robertson, 1876 (Family Rhizotrichidae)
The binomen Rhizothrix curvata was first mentioned as a nomen nudum in a species list by Brady and Robertson (1876: 197). Brady (1880a: 98) abandoned the intended generic name and described the species as Enhydrosoma curvatum, attributing authorship to “Brady & Robertson”. Sars (1909a: 302) erroneously claimed that Brady and Robertson (1876) had established the genus Rhizothrix and unfortunately this error has been perpetuated in the literature (e.g. Lang 1948; Bodin 1997; Boxshall & Halsey 2004; Wells 2007; Kornev & Chertoprud 2008). In fact, by providing a detailed generic diagnosis and therefore satisfying the provisions of ICZN Art. 12.1, Sars (1909a) himself had made the genus-group name available. Consequently this author should be credited with the authorship as Huys et al. (1996: 40) had recognized already.
The type species of Rhizothrix Sars, 1909a (by monotypy) is Enhydrosoma curvatum Brady, 1880a = Rhizothrix curvata (Brady, 1880a). It should be noted that the species cannot be attributed to “Brady & Robertson, 1880” or “Brady & Robertson in Brady, 1880a” since an outside person (i.e. other than an author of the work) can only be credited with authorship if he/she is alone responsible for the name and for satifying the criteria of availability (ICZN Art. 50.1.1). The same rule applies to the type species of the genera Jonesiella Brady, 1880a (Pseudotachidiidae), Normanella Brady, 1880a (Normanellidae), Robertsonia Brady, 1880a (Miraciidae) and Stylicletodes Lang, 1936b (Cletodidae), all of which have been erroneously attributed to Brady & Robertson by Brady (1880a) (Table 4).
Boxshall and Halsey (2004: 378) remarked that the traditional spelling of the family name, Rhizothricidae Por, 1986a, reflects an incorrect derivation that must be amended to Rhizotrichidae.
