Cyclinus Kirby, 1827

The nomen Cyclinus was first used by Kirby (1827) for a new genus accommodating a single North American species, C. assimilis . Subsequently, Aubé (1836) synonymized Cyclinus with Dineutus MacLeay, 1825 . Much later, Hatch (1925) resurrected the nomen Cyclinus for a subgenus of Dineutus , including the original species, Dineutus assimilis , and adding several other North American species. As with the nomen Cyclous , Article 50.3 of the Code applies, and although Hatch (1925) recognized the group at subgenus rank, authorship of the nomen belongs to Kirby (1827).

At the time of its original establishment, Cyclinus only contained a single species, C. assimilis , which is therefore the type species of Cyclinus through monotypy. Ochs (1926, 1927) incorrectly designated the type of Cyclinus as Dineutus americanus and attributed the authorship to Say without a date, despite D. americanus being attributed to Linnaeus (1767). The nomenclatural history of the two species, D. assimilis and D. americanus , is difficult and we refrain from discussing it here, as the scope of this paper is limited to genus and family nomina.
