Abstract: Six species of Orthoptera are reported as new to the Portuguese fauna: Cyrtaspis tuberculata Barranco, 2005, Natula averni (Costa, 1855), Oecanthus dulcisonans Gorochov, 1993, Pteronemobius heydenii (Fischer, 1853), Tetrix bipunctata kraussi Saulcy, 1888 and Stenobothrus grammicus Cazurro, 1888. The first documented records of Stenobothrus bolivarii (Brunner von Wattenwyl, 1876) and Omocestus viridulus kaestneri Harz, 1972 are presented, along with new records of some rare species: Leptophyes puncta- tissima (Bosc, 1792), Conocephalus conocephalus (Linnaeus, 1767), Metrioptera ambigua Pfau, 1986 and Sphingonotus nodulosus Llucià-Pomares, 2013.

Introduction Until recently the Portuguese Orthoptera fauna was relatively were used. Additionally moist areas were inspected for poorly studied. In recent years more and more data are being groundhoppers and for tree- and bush dwelling species published, e.g. Lock (1999), Miranda-Arabolaza & Barranco branches were beaten with a stick, collecting the specimens (2005), Ferreira et al.
