Ctenisodes piceus

As a member of Pselaphinae, Ctenisodes piceus is likely small-bodied with the characteristic compact, hump-backed form typical of the subfamily. Species in the genus Ctenisodes are distinguished by features of the antennae and pronotum; however, specific diagnostic characters for C. piceus require examination of type specimens or original description.

Associated with ant colonies, as indicated by the common name 'ant-loving beetle.' Specific microhabitat preferences are not documented.

Northeastern North America: Canada (New Brunswick, Ontario, Quebec) and eastern United States (Connecticut, District of Columbia, Massachusetts, Maine, Michigan, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Vermont).

• Ants - myrmecophilousSpecies is described as 'ant-loving,' indicating association with ant colonies; specific host ant genera not documented.

Myrmecophilous, living in association with ant colonies. Specific behavioral adaptations to ant colony life are not documented.
