Armadillidium pictum Brandt, 1833

Remarks and ecology

Species well distributed across Europe in different ecotypes. Rare and scarcely recorded species in the Iberian Peninsula, limited to northern areas, especially in the Pyrenean region: Huesca ( Schmölzer 1971, as A. garumnicum ); Navarra ( Schmölzer 1971, as A. garumnicum ; Fidalgo & Herrera 1980; Vivar et al. 1984; Cruz 1993, as A. pictum ); Andorra and Lleida ( Cruz 1993, as A. pictum ). The only two records in Asturias ( Cruz 1991a; Vázquez-Felechosa & Anadón 2001) need to be confirmed since they are based on female specimens that could have been confused with A. boalense sp. nov., which presents a similar habitus. The unique record in Galicia, also a female specimen ( Cifuentes 2019), comes from the type locality of A. galiciense and could correspond to this species, now revalidated. During our samplings in Asturias, we have not found Armadillidium pictum . We hypothesised that could be more restricted to the Pyrenean region, being replaced by A. boalense and A. galiciense in northern Iberian Peninsula. Little is known about its ecology, although it is considered a silvicolous species well adapted to other natural and seminatural habitats.
