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).
