“…We also found it in 2013 in a garden centre in Kamloops, in the drier interior of British Columbia (Table 2). On the Atlantic coast, D. invadens was found in 2012 on rough ground adjacent to gardens in St John's, Newfoundland (Forsyth 2014; confirmed by HR); the maritime influence there ameliorates winter temperatures.…”

The article reviews distribution records of Deroceras invadens (previously called D. panormitanum and D. caruanae), adding significant unpublished records from the authors' own collecting, museum samples, and interceptions on goods arriving in the U.S.A. By 1940 D. invadens had already arrived in Britain, Denmark, California, Australia and probably New Zealand; it has turned up in many further places since, including remote oceanic islands, but scarcely around the eastern Mediterranean (Egypt and Crete are the exceptions), nor in Asia. Throughout much of the Americas its presence seems to have been previously overlooked, probably often being mistaken for D. laeve. New national records include Mexico, Costa Rica, and Ecuador, with evidence from interceptions of its presence in Panama, Peru, and Kenya. The range appears limited by cold winters and dry summers; this would explain why its intrusion into eastern Europe and southern Spain has been rather slow and incomplete. At a finer geographic scale, the occurrence of the congener D. reticulatum provides a convenient comparison to control for sampling effort; D. invadens is often about half as frequently encountered and sometimes predominates. Deroceras invadens is most commonly found in synanthropic habitats, particularly gardens and under rubbish, but also in greenhouses, and sometimes arable land and pasture. It may spread into natural habitats, as in Britain, South Africa, Australia and Tenerife. Many identifications have been checked in the light of recent taxonomic revision, revealing that the sibling species D. panormitanum s.s. has spread much less extensively. A number of published or online records, especially in Australia, have turned out to be misidentifications of D. laeve.

“…The first serious collections of terrestrial molluscs on the Island of Newfoundland were made, somewhat incidentally, by Philadelphia botanist Bayard Long, who Reise et al (2011), andin Forsyth (2014). This collection is significant, since it constitutes only the second outdoor record of D. invadens for eastern Canada.…”

“…This collection is significant, since it constitutes only the second outdoor record of D. invadens for eastern Canada. The first eastern Canada outdoor record of D. invadens (Forsyth 2014) was also collected from St. John's, from a location approximately 0.9 km south-southeast of the second one. Interestingly, repeated attempts by JEM to rediscover D. invadens at the first site have been unsuccessful, suggesting that the occurrence at that particular spot was ephemeral.…”

The family Boettgerillidae, represented by the Eurasian slug Boettgerilla pallens Simroth, 1912, is first recorded for Newfoundland and Labrador, Canada-a range extension of almost exactly 5000 km within the Americas. Compiled, within an appendix, to provide a national perspective for the Newfoundland and Labrador record, are 13 previously unpublished B. pallens records from British Columbia, Canada. Incidentally recorded is the second eastern Canadian outdoor occurrence of the European slug Deroceras invadens. This paper is the first in a series that will treat all of the terrestrial molluscs of Newfoundland and Labrador.
