Thirteen species of Tenebrionidae are newly reported for New Brunswick, Canada. Paratenetus punctatus Spinola, Pseudocistela brevis (Say), Mycetochara foveata (LeConte), and Xylopinus aenescens LeConte are recorded for the first time from the Maritime provinces. Platydema excavatum (Say) is removed from the faunal list of New Brunswick, and the presence of Platydema americanum Laporte and Brullé for the province is confirmed. This brings the total number of species of Tenebrionidae known from New Brunswick to 42. Two species of Zopheridae, Bitoma crenata Fabricius and Synchita fuliginosa Melsheimer, are newly recorded for New Brunswick, bringing the number of species known from the province to four. Bitoma crenata is new to the Maritime provinces. Collection and habitat data are presented for these species.
Tenebrionidae, Zopheridae, new records, Canada, New Brunswick
The Tenebrionidae is the sixth largest families of beetles, with 1184 species known from North America (
Most Tenebrionidae occurring in eastern Canada are associated with forests and live in or are associated with dead wood; a few are subcortical. A number of species are associated with fruiting bodies of polypore fungi, and a few species are found on flowers and leaves. Most of our adventive species are stored product pests. For more details, see
The Zopheridae, which includes the Colydiidae (
The following records are based on specimens collected during a general survey by the first author to document the Coleoptera fauna of New Brunswick and from by-catch samples obtained during a study to develop a general attractant for the detection of invasive species of Cerambycidae.
Collection methodsVarious collection methods were employed to collect the species reported in this study. Details are outlined in
Distribution maps, created using ArcMap and ArcGIS, are presented for each species in New Brunswick. Every species is cited with current distribution in Canada and Alaska, using abbreviations for the state, provinces, and territories. New records for New Brunswick are indicated in bold under Distribution in Canada and Alaska. The following abbreviations are used in the text:

ResultsThirteen species of Tenebrionidae are newly reported for New Brunswick. Paratenetus punctatus Spinola, Pseudocistela brevis (Say), Mycetochara foveata (LeConte), and Xylopinus aenescens LeConte are recorded from the Maritime provinces for the first time; Platydema excavatum (Say) is removed from the faunal list of New Brunswick, and the presence of Platydema americanum in New Brunswick is confirmed. This brings the total number of species known from New Brunswick to 42 (Table 1).

Collection localities in New Brunswick, Canada of Synchita fuliginosa.
Most (16) adults from New Brunswick were captured in Lindgren funnel traps deployed in a mature hardwood forest, an old red oak forest, an old silver maple swamp, and an old red pine forest. Individuals with more specific bionomic data were reared from American elm (Ulmus americana L.) bolts and taken at an ultraviolet light. Elsewhere, Synchita fuliginosa have been found under bark of a variety of hardwood species or collected at light (
