Further contributions to the longhorn beetle (Coleoptera, Cerambycidae) fauna of New Brunswick and Nova Scotia, Canada

Abstract

Sixteen species of Cerambycidae are newly recorded for New Brunswick, Canada; Arhopalus obsoletus (Randall), Atimia confusa confusa (Say), Callidium frigidum Casey, Phymatodes amoenus (Say), P. testaceus (Linnaeus), Neoclytus mucronatus mucronatus (Fabricius), Xylotrechus aceris Fisher, X. sagittatus sagittatus (Germar), Tylonotus bimaculatus Haldeman, Lepturges angulatus (LeConte), L. symmetricus (Haldeman), Urgleptes querci (Fitch), Oplosia nubila (LeConte), Eupogonius subarmatus (LeConte), Monochamus carolin- ensis (Olivier), and Pogonocherus parvulus LeConte. Urgleptes signatus (LeConte) and U. querci are newly re- corded from Nova Scotia. All but two specimens were collected in 12-funnel Lindgren traps. Xylotrechus ace- ris, T. bimaculatus, L. angulatus, L. symmetricus, U. signatus (NS), and P. parvulus were detected exclusively in traps deployed in the forest canopy, and most individuals of O. nubila and M. carolinensis were captured in canopy traps. Arhopalus obsoletus, A. c. confusa, C. frigidum, P. testaceus, and X. s. sagittatus were captured almost exclusively in traps near (1 m above) the forest floor. Tese results highlight the importance of sampling both the understory and upper canopy when using traps for surveying diversity of Cerambycidae.
