Family Laelapidae Berlese, 1892 Genus Gaeolaelaps Evans and Till, 1966

Remarks — The genus Gaeolaelaps Evans et Till, 1966 includes over 100 described species. Most species were described from soil and litter, but some species were collected from nests of vertebrates and from arthropods (or their nests), including mygalomorph spiders, millipedes, cockroaches, termites, carabid, passalid, cerambycid, scarabaeid beetles and ants ( Bregetova, 1977d ; Karg, 1993; Beaulieu, 2009; Trach, 2012b, 2016; Kazemi et al., 2014). Only four species of Gaeolaelaps were previously encountered in Europe on carabids — G. nolli (Karg, 1962) on Agonum fuliginosum (Panzer, 1809) in Belgium, G. aculeifer (Canestrini, 1884) on Carabus intricatus Linnaeus, 1961 in Poland, G. carabidophilus Trach, 2012 on Stenolophus mixtus (Herbst, 1784) and G. khaustovi Trach, 2016 on Bembidion sp. in Ukraine ( Fain et al., 1995; Haitlinger, 2008; Trach, 2012b, 2016).
