Two New Species and New Records of Springtails (Collembola: Entomobryidae, Paronellidae) from Nevis, Lesser Antilles

This is the authors' abstract. We don't add key points for this paper.

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 [Arlé]).
