Abstract
First finding of Bicolorana bicolor (Philippi, 1830) and Euchorthippus declivus (Brisout de Barneville, 1848), new to the orthoptera fauna of South Tyrol (Insecta). In the framework of the ongoing project Biodiversity Monitoring South Tyrol findings of two orthopteran species hitherto unknown to the fauna of South Tyrol were made: both, Bicolorana bicolor and Euchorthippus declivus were found in summer and autumn 2021 in the surroundings of Altrei/Anterivo in the south of South Tyrol. The distribution of the species is shortly discussed and a suggestion for their red-list status is given. Due to their small range of distribution both should be treated as VU (Vulnerable).
