Status Pawson (1978) considered ascensionis as subspecies of D. antillarum based on its restriction to a few Atlantic Island Groups and wide distribiton of D. antillarum. Molecular data (mtDNA)of Lessios et al. (2001) confirmed that the Ascension Island populations are nested within D. antillarum. [details]
