Scanning electron microscopic study of adult stored product beetle mandibles

Adult stored product beetle mandibles were used as a subject for this scanning electron microscopic study. A total of 34 species are represented. Discussion is organized taxonomically by family, and comparisons are made between species where possible. Established terminology for morphological processes has been applied to all characteristics of mandibles reported in earlier literature; however, several new terms have been added in an attempt to better describe specific attributes of a species.
