[eng] Armadilloniscus Uljanin, 1875 is a genus of halophilic woodlice that strictly occurs in coastal habitats. Two species are known in the coastal areas of the western Mediterranean and only one species, A. ellipticus, was previously recorded in the Iberian Peninsula and the Balearic Islands. Another species, A. candidus, is reported for the first time in Asturias and the Iberian Peninsula. This species could have arrived to the Atlantic coast attached to floating objects, like logs, trunks or plants. The record shows the capability of A. candidus to adapt to coastal areas of the Atlantic. Until now, this species was only documented in the Atlantic by two single records from the French coast and the Azores islands. Ecological data are provided of this species in the Iberian Peninsula. Finally, figures of the habitus and of the morphological characteristics are provided, that allow the identification of the two species of Armadilloniscus present in the Iberian coastal areas.
