Ballistura ultonica was described by Carpenter (1911) as new to science from specimens collected in garden soil from Ballyclare, County Antrim. Unfortunately, no type specimens appear to have survived but from the description, it is likely that Carpenter's material was a species of Ballistura (8+8 ocelli, very long mucro, absence of apical ventral manubrial setae, one ventral seta on dens, empodium with a filament, tenaculum with 4+4 teeth). It seems to possess characters of both Ballistura filifera and Ballistura fitchi, but does not exactly match either. It is possible that 'ultonica' was an introduced species of Ballistura that could subsequently have been described as new to science from another country (or not at all). There are a few scattered literature records, mainly from Ireland but the identity of these is impossible to confirm unless specimens can be found.
