Abstract
Abstract We present the first records of species of Entomobryidae and Paronellidae (Collembola) from the Caribbean island of Nevis, from leaf litter collections on Mt. Nevis. We report 6 genera and 7 species, of which Dicranocentrus icelosmarias sp. nov. and Metasinella radkei sp. nov. are described as new. Evaluation of the dorsal chaetotaxy of D. icelosmarias sp. nov. suggests a closer affinity of Dicranocentrus to Heteromurus than to Orchesella. We provide a new interpretation of the homology of the dorsal chaetotaxy in Metasinella based on analysis of M. radkei sp. nov. The 6 genera reported here are widely distributed in the Greater Antilles, and the species composition shows a combination of endemics with affinities to other Antillean species (Dicranocentrus sp., Lepidocyrtus sp., Metasinella sp., Trogolaphysa sp.), species widespread throughout the northeastern Antilles (Entomobrya linda Soto-Adames), and adventive Neotropical species (Lepidocyrtus nigrosetosus Folsom, Seira brasiliana [Arle]).
