Forty-four species of Staphylininae are newly reported from New Brunswick, bringing the total number of species known from the province to 126. Quedius criddlei (Casey) is reported for the first time from Quebec. Bisnius cephalotes (Gravenhorst) is removed from the faunal list of New Brunswick due to a lack of supporting voucher specimens. Additional locality data are presented for seven species either recently recorded from the province or with few previous records and little habitat data. We provide the first documented records of Atrecus americanus (Casey), Quedius erythrogaster Mannerheim, Quedius labradorensis labradorensis Smetana, Quedius plagiatus (Mannerheim), and Neobisnius terminalis (LeConte) from New Brunswick. Collection and habitat data are presented and discussed for all species.
Staphylinidae, Staphylininae, new records, Canada, New Brunswick, United States, Maine
Intensive collecting of rove beetles (family Staphylinidae) in New Brunswick by the first author since 2003 has yielded many new provincial and national records. Additional records were obtained from by-catch samples during a study to develop a general attractant for detecting invasive species of Cerambycidae. These records are being published in a series of papers, each focusing on one or more subfamilies of Staphylinidae and other families of Coleoptera. This paper covers the subfamily Staphylininae.
This subfamily is fairly well known taxonomically in Canada and North America, thanks to various revisions. The genera Erichsonius and Neobisnius were revised by
Adults of Staphylininae live in a wide variety of habitats. Many species live in and near wetlands, including river and brook margins, lakeshores, vernal pool and pond margins, bogs, marshes, sea beaches, and various synanthropic situations (

Notes: *New to province; **New to Maritime provinces
The following records are based in part on specimens collected as part of a general survey by the first author to document the Coleoptera fauna of New Brunswick. Additional provincial records were obtained from specimens contained in the collection at Natural Resources Canada’s Atlantic Forestry Centre in Fredericton, New Brunswick.
Collection methodsVarious collection methods were employed to collect the Staphylininae reported in this study. Details are outlined in
Examples of most species of Staphylininae were dissected to confirm their identity. The genital structures were dehydrated in absolute alcohol, mounted in Canada balsam on celluloid microslides, and pinned with the specimens from which they originated.

ResultsForty-four species of Staphylininae are newly recorded from New Brunswick; Bisnius cephalotes (Gravenhorst) is removed from the faunal list of New Brunswick because of lack of a supporting voucher specimen. We provide the first documented records of Atrecus americanus (Casey), Quedius erythrogaster Mannerheim, Quedius labradorensis labradorensis Smetana, Quedius plagiatus (Mannerheim), and Neobisnius terminalis (LeConte) from New Brunswick. This brings the total number of species known from the province to 126 (Table 1). Thirty-three of these species are newly recorded for the Maritime provinces (New Brunswick, Nova Scotia, Prince Edward Island) of Canada. Additional locality data are presented for seven species either recently recorded from the province or having few previous records and little bionomic data. Quedius criddlei (Casey) is reported for the first time from Quebec.
