Abstract

Rove beetles (Staphylinidae) are diverse and dominant in many of North America’s ecosystems but, despite this and even though some subfamilies are nearly completely revised, most species remain difficult for non-specialists to identify. The relatively recent recognition that staphylinid assemblages in North America can provide useful indicators of natural and human impact on biodiversity has highlighted the need for accessible and effective identification tools for this large family. In the first of what we hope to be a series of publications on the staphylinid fauna of eastern Canada and the adjacent United States (ECAS), we here provide a key to the twenty-two subfamilies known from the region, a tribe/subtribe level key for the subfamily Staphylininae, and a species key to the twenty-five species of the subtribe Staphylinina. Within the Staphylinina, the Platydracus cinnamopterus species complex is defined to include P. praetermissus Newton spec. nov., P. cinnamopterus (Gravenhorst) and P. zonatus (Gravenhorst). Lectotypes are designated for Staphylinus cinnamopterus Gravenhorst, Staphylinus zonatus Gravenhorst and Staphylinus badius Mannerheim. One new Canadian record, one new record from eastern Canada, and thirty-nine new provincial or state records are presented.
