SM (HNHM pseud-1169: 1♀ ) ; Tatabánya : litter of purple smoke bush, 18.10.1960 , leg. IL (HNHM Pseud-1622: 5 adults ) . Habitat preference: this species has been previously reported from the litter of deciduous, pine and mixed deciduous forests, from moss, and in some cases from caves and tree hollows ( Beier 1951 ; Christophoryová et al. 2011a ; Novák 2012 ). In Slovakia it was also reported from compost heaps ( Christophoryová et al . 2017a ) and from tree hollows ( Christophoryová et al . 2017c ). In Hungary it has been reported from beech, oak and hornbeam forests, and from rock face in beech forest (Novák 2018). During the present investigations this species was found in the leaf litter of oak, beech, beech-hornbeam, and juniper forests, and from the litter of purple smoke bush. Remarks: Chthonius carinthiacus was described by Beier (1951) from Austria as a subspecies of Chthonius pygmaeus . It was later elevated to species level ( Gardini 2014 ). Christophoryová et al . (2011a) have reported it from neighbouring Slovakia , and Novák (2012) from several regions of Hungary . In the specimens from Hungary , the distal paraxial seta of fixed chelal finger displayed a sygmoid state.
