NB (New Canadian record). This Palaearctic species was not recognized by Casey (1889) in his monograph, unless as a synonym, but it was reported from North America the same year by Fauvel (1889) from MI and SC; the last record was by Ulke (1902) as the synonym tenellus (Erichson), from the District of Columbia (DC).

Natural history.

Carpelimus gracilis was collected by treading emergent Carex and grasses on a lake margin, sifted from decaying (moldy) corncobs and cornhusks and collected with an aerial net during evening flight between 16:30 & 20:00 h ADT in a mixed forest opening near a residential area. Adults were collected during May, June, and September.
