REMARKS This species is very common in the northern Iberian Peninsula, and in some Atlantic regions of Europe such as France, Belgium and the United Kingdom. It occurs in different habitat types and is not rare in caves, probably due to its preference for humid places (Kime & Enghoff 2011). This also agrees with its presence in the MSS in forested screes, as shown in the present study and in Eusébio et al. (2021). | Published as part of Gilgado, José D. & Ortuño, Vicente M., 2023, Polydesmid millipedes in the MSS of the northern Iberian Peninsula (Diplopoda, Polydesmida, Polydesmidae), pp. 451-461 in Zoosystema 45 (15) on pages 456-457, DOI: 10.5252/zoosystema2023v45a15, zenodo.org/record/8406495
