Distribution The species is known only from the spring of Bosna River (Vrelo Bosne) ( 581 m a.s.l.) near Ilidža, south of Sarajevo. This spring is draining the karst waters of the Igman Massif ( 1502 m a.s.l) and North Bjelašnica Massif ( 2067 m a.s.l.). Remarks The type species of the genus, Plagigeyeria plagiostoma , with P. inflata , were both originally described from the Bosna River Springs in Ilidža under the genus “ Geyeria ”, named after the famous German malacologist David Geyer ( 6 November 1855 – 6 November 1932 ). However the genus name was invalid due to homonymy, as it had been previously used by Buchecker in 1876 to name a moth in the family Castniidae Boisduval, 1828 , by Buckman in 1899 for a cephalopod, by Carapezzae & Schopen in 1899 for a brachiopod, and by Fucini, 1901 for a cephalopod. Based on the homonymy, Tomlin in 1930 renamed the genus “ Geyeria ” as Plagigeyeria with Plagigeyeria plagiostoma as type species and the Vrelo Bosna ( 581 m a.s.l.) as type locality for the genus. The species inhabits karst conduits under the Igman Massif ( 1502 m a.s.l.) and northern Bjelašnica Mountains ( 2067 m a.s.l.), likely drained from Prečko Polje ( 1002 m a.s.l.).
