Shetland revisited, for its sawflies (Hymenoptera: Symphyta: Tenthredinidae)

Field work in 2024‐2025 adds four species to the list of sawflies known to be established in the Shetland archipelago: Euura annulata (Gimmerthal, 1834), E . ferruginea (Förster, 1854), E . poecilonota (Zaddach, 1876) and Nematus septentrionalis (Linnaeus, 1758). The only published record of Euura melanocephalus (Hartig, 1837) from Shetland is based on a misidentification of E. ferruginea. Euura obducta (Hartig, 1837) is recorded for the first time in the northern group of islands (previously only found on Fair Isle). A total of 16 species are now known to be established. All are Tenthredinidae, and all but three are Nematinae. The species are listed in a table, with an indication of whether they are recorded in the northern archipelago and/???or Fair Isle.
