Abstract
Littoridinops monroensis Frauenfeld, 1863 was found in recent surveys in the Guanahacabibes Peninsula, Cuba. The species seems to be well established in this area with populations occurring in diverse habitats. L. monroensis has never been recorded from other monitored localities in the country and constitutes a new species record for Cuba. Its appearance in this survey may be because of a recent introduction. Migratory birds might have played an important role in the introduction since this region is a protected area and access is very restricted. Ecological data and the distribution of this species in Cuba is presented.
