Busycon sinistrum: Wise et al. (2004) considered B. sinistrum to be a subspecies of B. perversum. Their criterion for subspecies recognition was less than two percent observed DNA sequence divergence for cytochrome oxidase I, but this does not contradict a hypothesis that they are separate species, because recently evolved species might have little sequence divergence. The DNA data showed them to be reciprocally monophyletic. Also, there are many reports of B. perversum and B. sinistrum occurring in sympatry in the southern Gulf of Mexico, which contradicts subspecies status. Wise et al. (2004) suggested that the B. perversum morphology represents ecophenotypic variation in the presence of stone crabs, but did not present experimental evidence for induction of that morphology nor explain why stone crabs prey on Busycon in some areas and not others. Busycon sinistrum is therefore maintained as a species separate from B. perversum [GR]. Listed in the original Bulletin 89 (Rehder 1954) as B. contrarium Conrad, which name applies to an extinct species; see Hollister (1958).
