Caddisfly sampling conducted during August ۲۰۲۱ from the Gurgur River in the Sabalan Mountains, Ardabil province, Iran, revealed the first record of Glossosoma unguiculatum Martynov, ۱۹۲۵ for Iran. Previously, this species had only been known from few localities in Turkey, the Caucasus and Kazakhstan. The morphology of male genitalia in the collected specimens generally corresponds to the described species, with the exception of a less incised ventral margin of the abdominal segment IX in ventral view, which may be attributed to geographical variability. This discovery marks the second species of the genus Glossosoma Curtis, ۱۸۳۴ found in Iran.
