Eleven sawfly species are recorded from the largest wetland area in the Balearic Islands. Seven of these species are recorded for the first time in the archipelago, with one of them, Janus luteipes , being an addition to the recorded fauna of the Iberian Region. Keywords : sawflies, Symphyta, Mediterranean islands, wetland, biodiversity, faunal records, host plants.

Very little information on the sawfly assemblages of Sawflies (Hymenoptera Symphyta) are Mediterranean wetlands has hitherto been an under-recorded group in Mallorca. made available. Information for the Balearic Islands largely stems from the work of Wolfgang Schedl, who collated known records from a series Methods of sources, including specimens collected by his colleagues and himself (Schedl, Study area 1987).
