Abstract

The following three species of Helophoridae are newly recorded for New Brunswick, Canada: Helophorus (Kyphohelophorus) turberculatus Gyllenhal, Helophorus (Rhopaleloporus) oblongus LeConte, Helophorus (Rhopaleloporus) marginicollis Smetana. Hydrochus subcupreus Randall, family Hydrochidae, and the following 15 species of Hydrophilidae are newly reported for the province: Berosus fraternus LeConte, Berosus peregrinus (Herbst), Berosus sayi Hansen, Paracymus despectus (LeConte), Chaetarthria atra (LeConte), Cymbiodyta acuminate Fall, Cymbiodyta blanchardi Horn, Cymbiodyta minima Notman, Enochrus (Lumetus) hamiltoni Horn, Enochrus (Methydrus) consors (LeConte), Enochrus (Methydrus) consortus Green, Enochrus (Methydrus) pygmaeus nebulosus (Say), Cercyon (Cercyon) cinctus Smetana, Cercyon (Cercyon) herceus frigidus Smetana, Cercyon (Dicyrtocercyon) ustulatus (Preyssler).

Plain Language Summary

Knowing which species are present in Canada and how they are distributed is useful because it allows us to monitor future changes in species diversity and distribution that might happen as a result of a changing climate, habitat loss, and other forms of disturbance. This paper documents 19 new species of beetles never before recorded in New Brunswick, bringing the total number of species in these families known to occur in the province to 61, an increase of 25%. Most of the beetles in these three families are either aquatic or terrestrial species that feed on decaying vegetation, rotting mushrooms, or animal dung, but some are predaceous. Some of the new species records were collected in funnel traps as part of another study to develop improved methods of surveying for potentially invasive bark and wood-boring beetles. This paper improves our knowledge of insect species diversity and distribution in Canada.
