Stethophyma grossum : Ryabukhin & Zasypkina, 2005: 307 ; Ermakova, 2011: 21 ; Haberski et al. , 2021: 43 . Stethophyma lineatum (partim): Vickery, 1967: 269 ; Vickery & Kevan, 1983: 1080 ; Vickery, 1984: 20 ; Vickery, 1997: 229 . Remarks. A few specimens of this species have been recorded from Yukon , the Northwest Territories and Alaska as S. lineatum Scudder, 1863 ( Vickery & Kevan, 1983 ). Recently the specimens from Alaska were correctly identified as S. grossum ( Haberski et al. , 2021 ) . The records of isolated populations of S. lineatum from the extremely North Canada seem to be result of misidentification and belong to S. grossum . In Beringia , this Holarctis species has been recorded from Northeast Yakutia, Magadan region, Alaska, Yukon , and the Northwest Territories . This large and conspicuous grasshopper inhabits wetlands.
