Topics considered for publication include systematics, taxonomy, nomenclature, checklists, faunal works, and natural history. Insecta Mundi will not consider works in the applied sciences (i.e. medical entomology, pest control research, etc.), and no longer publishes book reviews or editorials. Insecta Mundi publishes original research or discoveries in an inexpensive and timely manner, distributing them free via open access on the internet on the date of publication. Insecta Mundi is referenced or abstracted by several sources, including the Zoological Record and CAB Abstracts. Insecta Mundi is published irregularly throughout the year, with completed manuscripts assigned an individual number. Manuscripts must be peer reviewed prior to submission, after which they are reviewed by the editorial board to ensure quality. One author of each submitted manuscript must be a current member of the Center for Systematic Entomology. Guidelines and requirements for the preparation of manuscripts are available on the Insecta Mundi website at http://centerforsystematicentomology.org/insectamundi/ Chief Editor: David Plotkin, [email protected] Assistant Editor: Paul E.

Forty new provincial records, including two new aleocharine species for the province of Manitoba (Coleoptera: Staphylinidae) are provided. The two new species, Acrotona manitobensis Klimaszewski and Go- din, new species, and Atheta manitobae Klimaszewski and Godin, new species, are described and illustrated. Habitat information and new locality records are provided for the newly recorded species. The current number of Aleocharinae in Manitoba stands at 120 species, including 40 new records and two new species described here. A checklist of all currently recorded species from the province, with their distribution records in Canada and USA, is included. Key words. Rove beetles, Nearctic, distribution, faunistics. Introduction Staphylinidae are the most species-rich family of Coleoptera with more than 63,495 described species in 3,762 genera worldwide (Newton, unpublished database, December 2017). Canada has 1,774 valid species recorded (Newton, unpublished database, December 2017; Klimaszewski et al. 2018) – an increase from the 1,652 species recorded from Canada listed in Bousquet et al. (2013). There are currently 511 described Aleocharinae species in Canada (A. Davies, unpublished data). The number of aleocharine species in Manitoba has increased to 120 (Klimaszewski et al. 2015a–c, 2016a–d, 2017a–d, 2018, and present data) since 69 species recorded by Bousquet et al. (2013). Aleocharine beetles are among the most poorly known and difficult-to-identify, megadiverse groups of Coleoptera, but enormous progress has been made in understanding their taxonomy in the last 20 years, especially in eastern Canada, where 407 species were recently recognized and treated (Klimaszewski et al. 2018). Western and north- ern Canada, Manitoba to British Columbia, and the three territories, however, remain poorly studied except for a few recent contributions to the knowledge of aleocharines in Alberta and Saskatchewan 2 • INSECTA MUNDI 0641, July 2018 KLIMASZEWSKI ET AL. (Klimaszewski et al. 2015a, 2016b,c), Yukon (Klimaszewski et al. 2008, 2012), and in coastal British Columbia (Klimaszewski and Winchester 2002; McLean et al. 2009a,b). For many species the full distribution in Canada is unknown because of the large gaps in sampling intensity (Klimaszewski et al. 2012, 2015a). Nonetheless, the fauna of these provincial and territorial jurisdictions is starting to receive more attention as many studies in recent years have sampled aleocharines in a large number of habitats, particularly in Alberta and Saskatchewan (Klimaszewski et al. 2016b,c). More intensive and less patchy sampling of Staphylinidae, and especially Aleocharinae, is needed to establish baseline biodiversity
