ABSTRACT = {	
The taxonomic history of the South American genus <i>Pomacea</i> Perry, 1810, and some shifts of systematic concepts during recent decades are briefly reviewed. Too many pre-evolutionist, shell-defined species created a gibberish, the only acceptable solution of which being perhaps a conventional, somewhat authoritarian decision based on expertise. The addition of other sources of morphological, biochemical, ecological or genetic information should not solve the problem if it is not accompanied by a sound reappraisal of the species concepts. Since the assumptions of each concept differ, any correspondence between them is irrelevant, and may drive to incompatible results. The shell variability of <i>Pomacea canaliculata</i> was acknowledged for most authors throughout more than a century. A recent insight into its life-history traits demonstrated they are as variable as the morphology. These findings stress the need of determining the ecological identity of any pest apple-snail population at a local scale, because its invading ability may be not exactly correlated to its taxonomical identity. Probably, all the <i>canaliculata</i>-like apple snails constitute a single, very variable “species” in most senses, even though different subsets may be recognized under other incommensurable concepts.},
