Identification
Identification to level in Lordithon requires examination of male genitalia and detailed comparison with . The Lordithon comprises small to medium-sized rove beetles with compact bodies and relatively short . L. anticus can be distinguished from the more common European species L. lunulatus, which has been introduced to North America, by subtle differences in body proportions and aedeagal structure. Reliable identification typically requires reference to original descriptions or specialized keys for Mycetoporinae.
Habitat
Presumed to inhabit decaying fungi, rotting wood, and other decomposing organic substrates based on affinities. Specific microhabitat preferences for this have not been documented.
Distribution
Recorded from Canada (New Brunswick, Nova Scotia, Ontario, Quebec) and the United States (Connecticut, District of Columbia, Iowa, Illinois, Indiana, Massachusetts, Maryland, Maine, Michigan, Missouri, Nebraska, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Virginia, Wisconsin). The distribution appears concentrated in the northeastern and north-central regions of North America.

Taxonomic history
Originally described as Bolitobius anticus by Horn in 1877, later transferred to the Lordithon. The genus Lordithon is part of the Mycetoporinae, which was historically classified within Tachyporinae but is now recognized as a distinct lineage.
Data limitations
This is rarely encountered in collections and has minimal published biological information. Most available data consists of specimen records and taxonomic descriptions rather than ecological studies.
