Faunistic updates on Greek ants: First record of Strumigenys membranifera (Emery, 1869) from Crete and Strumigenys baudueri (Emery, 1875) from Andros

The genus Strumigenys Smith, 1860 (Formicidae, Myrmicinae) comprises over 890 species worldwide. Strumigenys membranifera , a widely distributed tramp species, is known for its small size, thelytokous parthenogenesis and predatory behaviour. Herein, we report the first occurrence of S. membranifera from the island of Crete, Greece. Specimens were collected in olive orchard agroecosystems, located in the Messara Plain, using pitfall traps during surveys conducted in 2023 and 2024. In addition, we report the first occurrence of S. baudueri from the island of Andros, Greece, where specimens were collected from leaf litter. These records expand our knowledge of Strumigenys species on the island of Crete and the Aegean Islands and contribute to our understanding of the ecology and distribution of native and non-native members of this genus in Greece.
