Cryptolestes is a genus of beetles in the family Laemophloeidae. Several species are known as economically important pests of stored products, especially food grains. The four most notorious species are Cryptolestes ferrugineus, Cryptolestes pusilloides, Cryptolestes pusillus, and Cryptolestes turcicus. C. capensis, C. klapperichi, and C. ugandae are less widespread pests. Species in this genus can be hard to distinguish from one another, and definitive identification often requires close examination of the genitalia.
