Reflecting its isolation, geography, and glacial history, the Haida Gwaii archipelago (Queen Charlotte Islands, British Columbia) contains numerous endemic and disjunct taxa of various groups of organisms, but terrestrial gastropods have received scant attention. During surveys of 56 sites on Graham and Moresby Islands and 11 smaller islands, including remote mountain top locations, we detected 18 species of native terrestrial gastropods, most of which also occur in southwestern British Columbia. An undescribed species of semi-slug was found at four sites on Graham Island and six sites on Moresby Island and is formally described (Arionidae: Staala gwaii). Morphological and anatomical analyses suggest that the new slug is related to small species of Hemphillia Bland and Binney, 1872, but the differences are substantial, warranting the establishment of a new genus. The new species is of particular interest because it appears to be a northern endemic and a relict to the archipelago.

The European terrestrial snail Trochulus striolatus (C. Pfeiffer, 1828), found at one locality in the city of Revelstoke, is newly reported from British Columbia, Canada. This record appears to be the first time that this species has been found in western North America.
