FAMILY LATHRIDIIDAE (Minute brown scavenger beetles)
Y. Bousquet
Fifty-three species of lathridiids have been recorded from Canada and Alaska. These species are usually found on foliage, in rotten wood, under logs, bark of dead trees as well as in fungi and nests of social Hymenoptera, birds and mammals. A number of species, including Cartodere constricta and Aridius nodifer, are regularly found on stored products, especially damp and moldy ones. Adults and larvae feed on fungi, particularly molds. This is another family of Cucujoidea that has been poorly studied in North America. Most of the genera, particularly those of the subfamily Corticariinae, are in need of modern revision. Two subfamilies, the Lathridiidae and the Corticariinae, occur in the Nearctic Region. The generic classification of the Lathridiinae follows that of Walkley (1952).
