New molecular genetic analysis has conducted and leading to at least two species of Pomacea that attributed to as ‘golden apple snails’. One of these is most likely P. canaliculata but the identity of the other is not yet certain.

However, verification of the identity of this second species requires further research. There are a number of synonyms of both P. canaliculata and P. maculata, some of which have been used in the pest-related literature. It seems unlikely that P. lineata is one of the pest species. And although there is as yet no evidence for hybridization among the pest populations, this remains a possibility, which will increase the difficulty of providing a definitive species
