Note.

See Smetana (1995) for identification. Majka et al. (2009b) documented a significant range extension for this Philonthus species, shedding light on existing distribution gaps within the eastern rove beetle fauna. While this species displays a bipartite distribution pattern in Canada, Smetana (1995) indicated that it is a transcontinental species, with its presence in Quebec highly expected. Philonthus hepaticus has an extremely broad range in the New World and occurs south to Chile and Argentina. It has also become adventive in Australia and New Zealand ( Newton 2022). This species probably also occurs in at least some parts of southern Ontario.
