A new species of Glaresis Erichson from the Iberian Peninsula (Scarabaeoidea : Glaresidae)

Glaresis thiniensis new species is described from material collected at lig ht in littoral sand dunes from eastern Iberian Peninsula. A new record of t he other known Iberian species of Glaresis Erichson, G. hispana (Baguena), is provided. Diagnostic characters of both species include the presence/abs ence of mesotibial fossa in the metasternum, the form of the clypeus and me so- and metatibia, the number and size of teeth on the metatrochanter and f emora and the form of male genitalia. These characters and others as the fo rm of mandibles, length of metatarsomers, and the form of outer horseshoe-s haped portion of metatibia can be used to separate G. thiniensis from the N orth African species: G. mandibularis Petrovitz, G. tripolitana Petrovitz, G. carthagensis Petrovitz, G. pardoi Petrovitz and G. mauritanica Petrovitz . A map with the known distribution of the Iberian species is also provided .
