Julus spinosus Ribaut, 1904

Leucoiulus spinosus auct.

Cylindroiulus spinosus auct.

Distribution

ES-SPA, FR-FRA. Atlanto-Mediterranean.

Habitat

Deciduous, mixed and coniferous woodland. Recorded dominant trees include Fagus sylvatica , Fraxinus excelsior , Quercus petraea , Q. ilex , Abies alba and Pinus sylvestris , with a mention of Tilia in oakwood. Most records are montane, up to 1600 m, from leaf litter, under bark on the ground and in the soil. Under large stones beside tracks. The soil is often very light and sandy. Troglophile.

Remarks

A rather unusual known distribution centred on the Pyrenees with northward extensions to the Dordogne, Montagne Noire and the Massif Central, but, while most records are montane, it has been found in pinewoods near sea level in Aquitaine, in lowland caves and around Toulouse. The limits of its range are uncertain, both in France and in Spain.
