This record describes Neodimetrota tenuiducta (species). Recorded family: Staphylinidae. Recorded order: Coleoptera.

Identification and Appearance

This species bears close resemblance to A. burwelli, A. curvipennis, and A. caribou, but it can be distinguished from them by differences in the shape of male genitalia and some external characteristics. Females of this species may be confused with those of A. burwelli, and A. curvipennis, but may be differentiated by association with males which are more easily identifiable. Formerly known as A. prudhoensis in Klimaszewski works, but Muona (2023:21) detailed the historic confusion behind the names:

About Primitive Winged Insects: the wider group

Order-level background for Coleoptera, the group containing Neodimetrota tenuiducta. Species-specific details appear above.

Group overview

Coleoptera is the largest order of insects with over 400,000 described species, representing ~25% of all known animal species and ~40% of all insects. In the U.S. alone, nearly 30,000 beetle species have been identified.

Ecological role of the group

Beetles are prominent decomposers, especially in forests, breaking down dead wood and recycling nutrients. As predators, they reduce populations of pest insects. Many species are also important pollinators of flowering plants.

Economic and practical significance of the group

Beetles have major economic significance: leaf beetles (Chrysomelidae) and weevils (Curculionoidea) are among the most destructive agricultural pests globally, costing billions annually, while predatory species like ladybugs provide natural pest control.

Recorded sources for this group: Britannica, Smithsonian, NCSU Entomology. Imported estimates may describe particular regions or reporting periods.
