The distribution is unusual; beyond the Alps it reaches Belgium to the
northwest and Serbia to the southeast. Also recorded from Poland in the east by Enghoff & Kime (2009),
but as Leptoiulus simplex marcommanius, which is presumably Leptoiulus noricus Verhoeff, 1913. Its
distribution in Poland is logical for L. noricus and not for L. simplex. These records are not shown on
either map. Taxonomically close to L. alemannicus, its complicated taxonomic history was explained
by Spelda (1999).
