(Haldeman, 1853)
Cyclotrachelus gravidus is a ground beetle in the Carabidae, Pterostichinae. The Cyclotrachelus comprises medium to large-sized ground beetles found in North America. This was described by Haldeman in 1853 and is known from the United States. Like other members of its genus, it is presumed to be a ground-dwelling , though specific biological details remain poorly documented.

Identification
Members of Cyclotrachelus can be distinguished from similar ground beetles by their robust, somewhat flattened body form and characteristic elytral striation patterns. Specific features distinguishing C. gravidus from such as C. heros, C. constrictus, C. substriatus, and C. torvus would require examination of subtle morphological characters including pronotal shape, elytral microsculpture, and male genitalia. Detailed identification keys for this are available in technical carabid literature.
