Abstract

Formicoxenus nitidulus (Nylander, 1846) and Formica foreli Bondroit, 1918 are two social parasitic ant species with scarce Iberian records. First records for both species in the Eastern Catalan Pyrenees are presented, and also the previous bibliographical records. Males of F. nitidulus were found on the surface of Formica lugubris Zetterstedt, 1838 nests. The morphological differences among F. foreli and the other species in the subgenus líving in the Pyrenees are commented. A list of the other ant species found in the sampled localities is provided.
