Species Guides

The genus currently contains at least 16 described , with a documented distribution primarily in the Nearctic region. Unpublished records indicate presence in the Neotropics, suggesting the true range is broader than currently recognized. Most species were described by Fall and Brown in the early-to-mid 20th century, with several added by Peck and Cook in 2013.

Members of Anogdus can be distinguished from other Leiodidae by the combination of: body form compact and rounded; with distinct club; and specific male genitalic characters used in -level determinations. The genus is placed in tribe Leiodini, subtribe Anogdina, and is most similar to other anogdine genera such as Cyrtodirus and Agathidium, from which it differs in details of antennal structure and male genitalia . Species identifications require examination of male genitalia and are detailed in Peck and Cook (2013).

Taxonomic history
The was revised by Peck and Cook (2013), who described five new and provided keys to all known species. The subtribe Anogdina was established to accommodate Anogdus and related genera.
Research needs
The Neotropical fauna remains poorly documented; future collections and study are expected to reveal additional and expand known ranges of existing species.
