Taxonomy Reid et al. (2003) pointed out that the genus-group name Stygonitocrella Petkovski, 1976 was unavailable since no type had been designated. In the interest of preserving prevailing usage they re-established the genus by fixing Nitocrella montana Noodt, 1965 as the type species and by presenting an updated generic diagnosis (ICZN Arts 13.1.1, 13.3 and 16.1). Suárez-Morales and Iliffe (2005) continued to attribute authorship to Petkovski (1976), and proposed a subdivision of the genus in two new subgenera, Eustygonitocrella Suárez- Morales & Iliffe, 2005 and Fiersiella Suárez-Morales & Iliffe, 2005. As pointed out by Wells (2007: 89), since the subgenus Eustygonitocrella contains the type species of the genus, Stygonitocrella montana (Noodt, 1965), it must be replaced by the nominotypical subgenus and carry the name, author and date of the genus (ICZN Art. 44.1), i.e. Stygonitocrella (Stygonitocrella) Reid, Hunt & Stanley, 2003. Moreover, the subgeneric name Eustygonitocrella does satisfy the provisions of ICZN Art. 13.1.1 (it is accompanied by a differential diagnosis) but not those of Art. 13.3 (type fixation was not rigidly construed) and hence is permanently unavailable. Suárez-Morales and Iliffe’s (2005: 217) statement in the etymology section that “... the subgenus was named using the Greek prefix ‘‘eu’’ meaning ‘‘the original’’, to denote the inclusion, in this group, of the
type species of the genus Stygonitocrella (S. montana), designated by Reid et al. (2003)” does not qualify as a type fixation (ICZN Art. 67.5).
The status of the second subgenus, Fiersiella, is also problematic. Suárez-Morales and Iliffe (2005: 224) designated Nitocrella dubia Chappuis, 1937 as “... the representative species of the subgenus...”. However, type designation must be rigidly construed (ICZN Art. 67.5) preferably by using the term “type species” or a strictly equivalent term in another language (espèce-type, Typusart, specie tipo, etc.) (ICZN Recommendation 67A) to avoid ambiguity. According to these provisions Suárez-Morales and Iliffe’s (2005) designation cannot be considered valid and renders the genus-group name Fiersiella unavailable. It is here re-established as Fiersiella subgen. nov. by the explicit fixation of Stygonitocrella sequoyahi Reid, Hunt & Stanley, 2003 as the type species, taking the authorship and date of the present paper. Stygonitocrella sequoyahi is by far the most accurately described species in the subgenus and a much better candidate for the name-bearing type than Nitocrella dubia (the oldest species in the subgenus). The subgenus Fiersiella can be differentiated by the characters listed in the original diagnosis given by Suárez-Morales and Iliffe (2005: 223) (ICZN Art. 13.1.1). According to these authors the subgenus includes Nitocrella dubia Chappuis, 1937 = Stygonitocrella (Fiersiella) dubia (Chappuis, 1937), N. karamani Petkovski, 1959 = S. (F.) karamani (Petkovski, 1959), N. ljovuschkini Borutzky, 1967 = S. (F.) ljovuschkini (Borutzky, 1967), N. colchica Borutzky & Mikhailova- Neikova, 1970 = S. (F.) colchica (Borutzky & Mikhailova-Neikova, 1970), Stygonitocrella petkovskii Pesce, 1985a = S. (F.) petkovskii (Pesce, 1985a) and S. (F.) sequoyahi Reid, Hunt & Stanley, 2003. Wells (2007: 37–38) inadvertently assigned these species to the subgenus Stygonitocrella and vice versa. [details]
