Species text

Sabacon viscayanus is represented in Britain by the sub-species ramblaianus. It is probably a recent introduction (first record: 1980 on the Gower Peninsula) spreading throughout Wales and more recently found in the Wyre Forest area in Worcestershire (2013) and Devon (2014). Its European distribution is centred on the Pyrenees.

Habitat and ecology It is found in damp woodland (mixed and deciduous), utilising deep litter and woodland edge debris. It has also been recorded in subterranean habitats (as in other sabaconids).

Adult females have been recorded between June and October but very little is known about its life-cycle or feeding habits. The dense, brush-like covering of glandular setae on the pedipalps suggests it may be suited to mopping up small invertebrates such as springtails.

Probably an introduced species, which is spreading rapidly.
