Pseudotychius watsoni
Pseudotychius watsoni is a small brentid weevil in the subfamily Nanophyinae, described by Blatchley in 1922. The species has been suggested to associate with Decodon verticillatus (swamp loosestrife), a wetland plant in the family Lythraceae, though this host relationship requires confirmation. It is known from Ontario, Canada, and like other members of its subfamily, likely occupies aquatic or semi-aquatic habitats tied to its host vegetation.
