New species of Entomobrya from Etna Mountain, Sicily (Collembola, Entomobryomorpha)

Sicily is described. Entomobrya siciliana n. sp. is separated from all other known species by the following combination of characters: characteristic colour pattern, ratio antennae/head length ≈2, apical vesicle bilobated, labral papillae almost smooth, with two small projections on central ones, claw with 4 internal teeth and empodium with serrate external edge (leg III). The macrochaetotaxy is described. For the identification and description of these species we used the set of characters proposed by JORDANA and BAQUERO (2005).
