Abstract
Roncus elbulli sp. n. is described from Cap de Creus Nature Park (Catalonia, Spain). The new species is morphologically close to Roncus cadinensis Zaragoza, 2007 (Barcelona province), but differs by being smaller in size anda more robust chela with a different microsetae pattern. The new species seems to be restricted to coastal semiarid slopes with garrigue vegetation. A key to the Spanish species of the genus Roncus is provided.

Three species of the genus Roncus L
This study reveals that the Roncus of Catalonia colonize diverse types of habitats and that this is partly responsible for their endemicity
Gabbutt and Vachon (1967) pointed out difficulties in the taxonomy of the genus Roncus, due to the inadequate help that morphometry provides in discriminating between species
Summary
Three species of the genus Roncus L. We describe an additional new species of this genus from Cabo de Creus Natural Park, province of Gerona, Catalonia, Spain. This new discovery supports Zaragoza and Šťáhlavský’s (2008) suggestion that more endemic species of Roncus remain undiscovered or misidentified in Northeast Spain, as well as in Southeast and Balearic islands This study reveals that the Roncus of Catalonia colonize diverse types of habitats and that this is partly responsible for their endemicity
