Concerning valid type species fixation for the genus-group taxon, please consult Art.  67.2.1. In the meaning of the Code the "originally included nominal species" comprise only those included in the newly established nominal genus or subgenus, having been  cited in the original publication by  an available name (including citation by an incorrect spelling [ Art. 67.6 ]) of a species or subspecies (see Articles  45.6  and  68.2 ), or having been cited there as the deliberate application of a previous misidentification (see Articles  11.10 ,  67.13  and  69.2.4 ). http://www.nhm.ac.uk/hosted-sites/iczn/code/?article=31

So, if a species is designated by unavailable name, and this name is cited in the original publication of a new genus, it cannot be used as a type to define this genus genus.
