Notities over Kwartaire land- en zoetwatermollusken in Nederland – Pseudotrichia rubiginosa (Rossmässler, 1838)

The fossil occurrence of Pseudotrichia rubiginosa in Netherlands' Quaternary deposits is reviewed. The species is known in 14 localities. The assemblages are discussed and short notes are made concerning the stratigraphy. Eight records are Holocene in age, two records in this group date from Subboreal and Subboreal/Atlantic times respectively, whereas the remaining Holocene records can be assigned to the Subatlantic. Three records are from Eemian deposits, most probably originating from the late interglacial phase. Further, the species is reported twice from deposits of the Late Tiglian interglacial phase (Early Pleistocene). It appears that Pseudotrichia is not a relative newcomer in the Netherlands. Contrary to Central Europe the species does not occur in wet loess deposits, so far all records are from tidally influenced deposits from interglacial times.
