Smetana (1995: 331) wrote, “ Philonthus couleensis is a pronouncedly hygrophilous species, occurring in a wide variety of wet habitats … even in marshy habitats along sea beaches”. There are scattered records in New Brunswick, Newfoundland, and Nova Scotia ( Smetana 1995) including a few from coastal habitats. Its distribution in North America is shown in Smetana (1995).
