New Records of Coleoptera from Wisconsin Jordan D. Marché II 5415 Lost Woods Court, Oregon, WI 53575

Abstract Specimens of eleven different species of beetles (one of which is identified only to genus) have been collected from and are herein reported as new to Wisconsin. These species collectively occur within seven different families: Leiodidae, Latridiidae, Scirtidae, Throscidae, Corylophidae, Staphylinidae, and Dermestidae. A majority of the specimens were collected at the author’s residence, either in pan traps or at UV lights; the others were taken at two nearby (township) parks.

Although Wisconsin’s coleopteran four antennomeres. Antennal grooves may be fauna is large and diverse, new findings con- found beside the eyes (Peck 2001). Currently, tinue to reveal previously unrecorded genera four species within the genus are recognized and species, at least those collected from one from the continental U.S. and Canada: Z. southern county in particular (Dane County). bifoveolatus Daffner, Z. rubricornis Daffner, Over the past few years, but chiefly during Z. oklahomensis Daffner, and Z. egenus. 2016, the author has employed a variety of The first two species on this list are known collecting techniques, including (passive) only from extreme southern Florida, while usage of pan traps and UV lights, along with Z. oklahomensis has a known distribution more traditional (and active) field techniques of Alabama, Arkansas, Florida, Oklahoma, of examining logs, flowers, etc. Such efforts Texas, and Virginia.
