Taxonomic notes

Based on the newly available material (Supplementary file 2), this species was studied in the SEM (Figs 9–10, 17) and its pronotum is illustrated (Fig. 57).

Habitat and distribution

Soil-dwelling species found also at the entrance of caves and in their deep zones when abundant organic matter is available (Condé 1974; Sendra et al. 2012). It is common and well distributed in central and eastern Europe (Tuxen 1930; Paclt & Rusek 1961; Condé 1956a; Rusek 1965b; Paclt 1969; Blesić 1984, 1997a, 2001; Christian 1992; Sendra et al. 2012), extending its distribution southerly towards central Italy (Condé 1966; Ramellini 2000).
