This species was described from Germany and is broadly distributed throughout Germany ( Zaenker & Nagel 1999), France ( Ginet 1996), Luxembourg ( Hartke et al. 2011), Netherlands ( Stock 1961; Cuppen, 1978a,b) and Belgium ( Fig. 5 , App. 1). All studies (e.g. Martin et al. 2009), including ours, suggest this is the most widespread species in Belgium, and indeed, it was present in 65% localities ( Fig. 5 ; list and App. 1). The species seems to be found in all habitats, from running waters, caves to springs. Our results are concordant with data from neighboring South Limburg ( Netherlands, Stock 1961; Cuppen 1978a,b).

Some authors considered it as subspecies of N. aquilex (e.g. Zaenker & Nagel 1999), but molecular phylogenetic studies clearly rejected its subspecies status ( Fišer et al. 2008). Genetically it is only modestly differentiated, although cryptic species within the complex cannot be ruled out ( Hartke et al. 2011, McInnerney et al. 2014). Noteworthy, the samples from Belgium turned to be rather heterogeneous morphologically. One of the diagnostic characters (inner ramus of uropod I shorter than outer) turned to be polymorphic, i.e. inner ramus as long as or even slightly longer than outer ramus. We suggest that other characters, like elevated number of retinacles in pleopods, are more reliable for identification of Belgian populations of this species.
