Abstract

The rare Dolomedes plantarius has been observed in a permanent pond (“ullal”) in the Ebro Delta (Catalonia, north-eastern Spain). This is the most meridional record registered in the Iberian Peninsula, and perhaps in western Europe. Thus, the pres­ence of this semiaquatic species may vary our assumptions on its rarity. Such finding evidences the relevance of aquatic envi­ronments in general and “ullals” in particular for biodiversity conservation, as well as the importance of considering both the semiaquatic and the terrestrial species inhabiting them.
