Abstract

This paper treats the discovery of new species and new records of Staphylinidae from the subfamilies Omaliinae, Proteininae, Tachyporinae, Oxytelinae, Scydmaeninae, Steninae, Euaesthetinae, Pseudopsinae, Paederinae, and Staphylininae for the province of New Brunswick and other provinces of Canada, and the USA. We report here two species new to science, three new North American records, nine new Canadian records, two new USA records, and 50 new provincial records. The following are the species new to science: Proteinus hughesi Webster & Davies, sp. n. and Proteinus sweeneyi Webster & Klimaszewski, sp. n. (Proteininae). Sepedophilus immaculatus (Stephens) and Carpelimus erichsoni (Sharp), Carpelimus mundus (Sharp) are newly recorded from North America. New Canadian records are as follows: Carpelimus difficilis (Casey), Carpelimus gracilis (Mannerheim), Carpelimus lacustris (Notman), Carpelimus probus (Casey), Carpelimus pusillus (Gravenhorst), Carpelimus rivularis (Motschulsky), Carpelimus spretus (Casey), Carpelimus weissi (Notman) (Oxytelinae), and Edaphus lederi Eppelsheim (Euaesthetinae). This is the first record of the genus Edaphus for Canada. Bledius basalis LeConte and Carpelimus obesus (Kiesenwetter) (Oxytelinae) are removed from the faunal list of New Brunswick. Proteinus acadiensis Klimaszewski and Proteinus pseudothomasi Klimaszewski are newly recorded from the USA and several provinces of Canada. Habitat data from New Brunswick are provided for most of the species treated in this contribution.

Highlights

In recent years, the Staphylinidae of New Brunswick have been studied intensively
Species with a † are adventive to Canada, species with a ‡ are either Holarctic or adventive to Canada, species with a * are Holarctic
The determination that a species was a new record is based on information in the print version of Bousquet et al (2013)

Summary

Introduction

The Staphylinidae of New Brunswick have been studied intensively. In a series of papers published in a Special Issue of ZooKeys (186), Biosystematics and Ecology of Canadian Staphylinidae, 184 species of Staphylinidae were newly reported from New Brunswick in the following 15 subfamilies: Omaliinae, Micropeplinae, Phloeocharinae, Olisthaerinae, Habrocerinae (Webster et al 2012d), Pselaphinae (Webster et al 2012a), Tachyporinae (Webster et al 2012e), Aleocharinae (Webster et al 2012b), Scaphidiinae, Piestinae, Osorinae, Oxytelinae (Webster et al 2012f), Oxyporinae (Webster and DeMerchant 2012a), Paederinae (Webster and DeMerchant 2012b), and Staphylininae (Webster et al 2012c). In a recent review of the Euaesthetus (Euaesthetinae) of North America, Puthz (2014) added nine members of this genus to the faunal list of the province. In this special issue, Webster et al (2016b) and Klimaszewski et al (2016) report another 66 Aleocharinae new to New Brunswick, including 30 species new to science, one new North American record, six new Canadian records, and 29 new provincial records. The purpose of this paper is to report on these new discoveries
