F. neglectissima occurs in Southern Poland and Ukraine.[1] [2]

F. neglectissima was originally assessed as Near Threatened (LR/nt) for the 1996 IUCN Red List, as it is restricted to springs in a small geographical area. However, individuals have not been found since 1988 and it is currently considered data deficient; it is listed as critically endangered in the Polish Red Data Book of Animals.[1]
