Species Guides
1Anchorius is a of small beetles in the Biphyllidae, first described by Casey in 1900. The genus was long known only from North America, with Anchorius lineatus as the sole described , until the recent description of Anchorius dollyae from Chile extended its range to South America. Members of this genus are distinguished by specific morphological features of the pronotum, ventrites, and male genitalia. The Chilean discovery represents the southernmost record of the genus.
