Since this species was observed for the first time on Saint-Barthélemy in 1995 (Breuil M, 2002, Histoire naturelle des amphibiens et reptiles terrestres de l’archipel Gua- deloupéen, Paris: Muséum national d’Histoire naturelle, 339 p.), 15 specimens have been found, mostly adults. The first juvenile was found dead in November 2011 (Questel K, 2012, Contribution à la connaissance d’Alsophis rijgersmaei [Squa- mata, Dipsadidae, Xenodontinae] sur l’île de Saint-Barthélemy, Gustavia, Saint-Barthélemy: Réserve Naturelle de Saint-Bar- thélemy & ALSOPHIS, 24 p). The discovery of this second ju- venile indicates that the species has become established on the island. It is currently too early to know the impact of this invasive snake on local biodiversity.
