Distribution and Habitat
This species was first collected from a site near Dublin in 1978. Further specimens were found on this site in 1979 and another location near Dublin in 1981. During the BMIG Field Meeting in 2004 it was collected with Geoglomeris subterranea from Aston Clinton, Buckinghamshire (Harper & Richards, 2006). Further specimens were collected from a nearby site later the same year and from Great Missenden, Buckinghamshire in February 2006. Insufficient habitat data are available for analysis but the British and Irish sites share similarities with the French sites in the western Pyrenees (Mauriès, 1960; Demange, 1981). The French and British specimens were all collected from scrub or woodland on calcareous soils. At least one of the Irish sites was an area of cleared scrub on limestone (Blower, 1985). Although all of the specimens found so far were collected by hand searching (in soil, under stones, under moss, and in leaf litter), it is possible that Berlese extraction or related techniques would be more productive for sampling this species.
Outside of Britain and Ireland it is known only from the western Pyrenees. However, Kime (2001) considers it may have been overlooked in western France and may possibly have an Atlantic distribution. The Irish records have included adult females in September, November and February and adult males in February. Adults of both sexes were found in April in Buckinghamshire.
