Isarthrus calceatus (Say, 1836)

In Canada, this uncommonly encountered eucnemid species was taken in Ontario and Québec. In the United States, I. calceatus was previously recorded from Arkansas, Connecticut, District of Columbia, Georgia, Illinois, Indiana, Iowa, Kansas, Maine, Maryland, Massachusetts, Michigan, Missouri, New Hampshire, New Jersey, New York, North Carolina, Ohio, Oklahoma, Pennsylvania, Rhode Island, South Carolina, Texas, Vermont, West Virginia and Wisconsin ( Otto 2022b, 2024b; Wickham 1911). Herein, I confirm a new state record for this species from Kentucky. One specimen was taken from a Lindgren funnel placed in a forested area following a prescribed burn. One specimen was also taken from a Lindgren funnel trap placed in an unburned forested area in Kentucky.
