dct:abstract

Gulella (Huttonella) bicolor (hutton, 1834), an invasive streptaxid land snail now circumtropical in distribution, is recorded for the first time from the Society Islands of French Polynesia, on the islands of Maupiti and Mo'orea, and its distribution in the islands of the Pacific is reviewed. Although its origin has been in question, previously overlooked paleontological studies indicate that G. bicolor is native to India. Gulella bicolor preys on terrestrial mollusks and its presence increases the threat of the extinction of what remains of the Society Islands' rich fauna of endemic land snails, already at risk because of anthropogenic habitat modification and the earlier introduction of other alien molluscivores.
