The Ciidae of New Brunswick, Canada are reviewed. Seventeen species are recorded for New Brunswick, including the following 10 species that are newly recorded for the province: Ceracis singularis (Dury), Ceracis thoracicornis (Ziegler), Cis angustus Hatch, Cis fuscipes Mellié, Cis horridulus Casey, Cis striatulus Mellié, Dolichocis laricinus (Mellié), Malacocis brevicollis (Casey), Orthocis punctatus (Mellié), and Plesiocis cribrum Casey. Additional locality data are provided for the following species previously known from the province: Cis americanus Mannerheim, Cis creberrimus Mellié, Cis levettei (Casey), Cis submicans Abeille de Perrin, Dolichocis Manitoba Dury, Hadreule elongatula (Gyllenhal), and Octotemnus glabriculus (Gyllenhal). Seven synonyms are proposed here: Cis pistoria Casey with C. submicans Abeille de Perrin; C. fraternus Casey, C. macilentus Casey and C. striolatus Casey with C. striatulus Mellié; Dolichocis indistinctus Hatch with D. laricinus (Mellié); and Octotemnus denudatus Casey and O. laevis Casey with O. glabriculus (Gyllenhal). Lindgren funnel traps provided the majority of specimens for 15 of the 17 species reported from New Brunswick and were the sole source of specimens for seven of the 10 species newly reported here, suggesting they are a very useful tool for sampling Ciidae in the forests of New Brunswick
Plain Language Summary
Ten species of minute tree-fungus beetles in the family Ciidae have been newly discovered in New Brunswick. These species had never before been observed and documented as occurring in the province. Both the larvae and adults of minute tree-fungus beetles live in and feed on “conks”, that is, the fruiting bodies of fungi that usually sprout from tree trunks or logs. The main point of this paper is to improve the knowledge of species diversity and composition of beetle fauna in Canada. The more we know about the distribution and composition of our forest insect fauna, the more readily we can detect changes in species abundance and distribution that may result from forest disturbances, e.g., changing climate or invasive species. Many of the beetle specimens in this paper were incidentally collected in traps that were part of experiments designed to develop improved tools for survey and detection of potentially invasive wood-boring beetles. In most trapping studies, incidental “non-target” species collected in traps are ignored. However, we took advantage of the opportunity provided by our trap samples to identify non-target species in many beetle families, including the Ciidae, and in doing so, have improved the knowledge of beetle species diversity and distribution in Canada.
