In Spain, this species is limited to northern Iberian Peninsula, from Galicia to Gerona (a summary of most of these records is included in Dollfus 1892 ; Fidalgo & Herrera 1980 ; Cruz 1993 , Schmölzer 1955 , 1971 ; Vivar et al. 1994; Vázquez-Felechosa & Anadón 2001 , Cifuentes 2019 ) ( Fig. 1A ). It had already been recorded in Asturias ( Schmölzer 1955 , 1971 ; Vandel 1962 ; Vázquez Felechosa & Anadón 2001). We provide here several new localities. This species was usually found in several habitats: different native forest masses, eucalyptus plantations, meadows, rural areas, gardens, rocky walls, and coastal habitats. A. nasatum was always located under logs, stones or other structures that create humid and shady microhabitats and our ecological observations agreed with those provided by Vandel (1962) .
