Diagnosis

In the eastern North American fauna, O. nitens   can be recognized using the diagnosis given by Brunke et al. (2011) (http://cjai.biologicalsurvey.ca/bnkmm_12/species_pages/ocyn.html) but can also be reliably identified from photos by its characteristically convex head and pronotum, and the relatively short elytra compared to the pronotum (Fig. 1). Superficially similar species of Tasgius   (http://bugguide.net/node/view/868738), also adventive in North America, are more flattened dorsoventrally compared to Ocypus nitens   (http://bugguide.net/node/view/862165).

Distribution

North America (adventive) (Fig. 2 ): Canada (ON); United States (MA, ME, NH, NY, RI, VT).

Ocypus nitens   is newly recorded from Canada (Ontario) and the state of Vermont (United States). Its native range in the Palaeartic Region includes Europe, Russia, Iran and Turkey ( Schülke and Smetana 2015).

Taxon discussion

For a period of more than fifty years (1944-2000), the adventive species Ocypus nitens   was known only from a small area in New England ( Newton 1987, Brunke et al. 2011; Fig. 2 (colored dots)). The expansion of its range westward (Ontario and New York) and northward (Maine) appears to have been recent and rapid, though the reasons for this remain unknown. Newton (1987) reported non-brachypterous individuals in North America, which may be expected to fly, at least occasionally. Their presence on several islands in New England supports this, though they could have been transported there with soil or other organic debris. There is a possibility that Ocypus nitens   remained undetected in Ontario and New York for much of this fifty year period due to a lack of sampling. However, this scenario is considered unlikely, especially for southern Ontario, which has had a long history of collecting by professionals and students in rural and urban habitats. Furthermore, many adventive staphylinid species that now occur broadly in eastern North America were first detected in southern Canada during this period ( Klimaszewski et al. 2013). Ocypus nitens   is large (12-20 mm, ( Schillhammer 2012)) and typically found in human disturbed habitats including woodlots and backyards, making it likely to be encountered by homeowners, naturalists and entomologists alike. Indeed, this is reflected in the number of recent photographic records available on BugGuide. This online, community-based resource continues to be an important source of first detections of adventive species in Canada, the United States, or the entire Western Hemisphere ( Kaldari et al. 2011, Carlson et al. 2012). Gibbs and Sheffield (2009) demonstrated that a rapid range expansion of an adventive bee species was captured by digital insect collections, including BugGuide, and emphasized their effectiveness when coupled with adequate identification resources or taxonomic expertise. Citizen science-based observation data, especially when verified, have become a cost and time-effective option to answer large-scale questions about insect distributions for certain groups that are taxonomically well-known and conspicuous, such as lady beetles ( Coccinellidae   ) ( Gardiner et al. 2012).

Ocypus nitens   joins Ocypus aeneocephalus   (DeGeer), Tasgius ater   (Gravenhorst), T. melanarius   (Heer) and T. winkleri   (Bernhauer) as the largest adventive staphylinids established in Canada and can be expected to eventually occur in Quebec and the Maritime Provinces. The even larger adventive species Ocypus olens   ( Müller) has become established in western North America but is still restricted to the western United States (Washington, Oregon, California and Arizona) and unknown from Canada ( Newton et al. 2001, BugGuide). This is another staphylinid that would be easily monitored by citizen science. The impact of these large species on related, native edaphic rove beetles ( Platydracus   and Dinothenarus   ) occupying similar microhabitats is unknown but several Platydracus   species appear to be less abundant than they were at the beginning of the 20th century ( Brunke et al. 2011).
