Armadillidium tabacarui (Isopoda: Oniscidea: Armadillidiidae), a new troglobitic species from a sulfurous cave in Romania

Four species of terrestrial isopods belonging to Caucasonethes, Haplophthalmus, Trachelipus and Armadillidium were collected in Movile Cave, Romania. Trachelipus troglobius was described recently and Armadillidium tabacarui, a new species, is described here. It was collected in the lower level of the cave where it is present in large numbers on the walls of the cave's airbells. It feeds on the rich chemoautotrophic microbiota covering the walls.
