Seven new species of Laboulbeniales parasitizing beetles (Coleoptera) are described: Corethromyces hernandoi and C. obscuristipes on Medon sp. (Staphylinidae), Eucantharomyces philorhizicola and E. rugatus on Philorhizus crucifer confusus (Carabidae), Eusynaptomyces cornutus on Hydrobius fuscipes (Hydrophilidae), Hydrophilomyces aduncus on Ochthebius dilatatus (Hydraenidae), and Monoicomyces myllaenae on Myllaena elongata (Staphylinidae). In addition, four other Laboulbeniales are reported. Arthrorhynchus nycteribiae is confirmed for Spain and the structure of its rhizoidal haustorium is described. The remaining three species are new records for Spain: Stigmatomyces borbori, S. canzonerii, and S. ceratophorus; the first two are second world records because the taxa were only known from type collections, from Cameroon and Senegal, respectively. © 2006 J.
