Inophloeus robustus (Broun, 1917) new combination Catoptes robustus Broun, 1917:414 Catoptes ‘ robustus Broun, 1917 ’, non (Sharp, 1886); Macfarlane et al., 2011:435 Inophloeus Pascoe, 1875 is a composite genus, as currently defined. However it is outside the scope of this paper to fully resolve the difficulties posed by the group. This species is congeneric with Inophloeus villaris Pascoe, 1875 and so it is placed within Inophloeus until such a time as the whole group is fully revised. This species is found in the Canterbury mountains, especially around Mt Hutt. According to Article 59.2 of the International Code of Zoological Nomenclature (ICZN, 1999), removal of this taxon from Catoptes prevents it from requiring a replacement name, despite the secondary homonymy caused by the placement of Tigones robustus Sharp, 1886, into Catoptes by Kuschel (1969).
