Identification
Distribution and Habitat
This species is virtually confined to Ireland, where it is locally common across much of the south-east.
It was unknown in Britain until 1994 when a site was discovered in south Wales. In 2010 a population was discovered in Mid-Lothian, Scotland (Sivell & Gregory, 2012) and a detailed account of its occurrence there is given by (Maguire, 2020).
It is characteristically associated with river and stream valleys, often inhabiting rough vegetation beside watercourses, where it occurs among leaf litter, under stones and dead wood.
This summary is based on the detailed account in Gregory (2009).
