    ABSTRACT
    The presence of Saga pedo (Pallas, 1771) (Ensifera Tettigoniidae Saginae), in the Euganean Hills area (Veneto, north-eastern Italy) is reported here for the first time. Observations were conducted between 2023 and 2025 in dry grasslands located in several municipalities of the area. The environment, characterized by xerothermophilous vegetation, hosts a diverse community of orthopteroid insects, potential prey of the species. Additional notes are provided on developmental stages, observation times, and some behavioral aspects. The occurrence of S. pedo in the Euganean Hills represents the first confirmed record for this area and expands the known distribution range of the species in Veneto region. This finding confirms the high biogeographical and conservation value of the Euganean Hills system. Consequently, it is recommended that Euganean dry grasslands be reconsidered among the habitats deserving priority protection due to the presence of S. pedo, and that entomological surveys be continued to assess the stability of the local population.

    ABSTRACT
    Neoscona byzanthina (Pavesi, 1876) (Arachnida Araneae Araneidae) is reported for the first time in Italy. Following the original description from Turkey and one report for Greece, the species has long been considered a synonym of Neoscona adianta (Walckenaer, 1802). Recently, it was re-established as a valid name and documented for France and Spain.
