The 9 species of the Lasionycta leucocycla complex are reviewed and the number of species reduced to 4. Populations of these species are arranged in 18 subspecies, of which 3 are described as new: L. leucocycla magadanensis Kononenko and Lafontaine, from Magadanskaya Oblast’, L. staudingeri sajanensis Kononenko, from southern Siberia, and L. quadrilunata yukona Lafontaine, from northwestern Canada. Lasionycta dovrensis (Wocke), of the Palaearctic region, is treated as a subspecies of L. leucocycla. Characters to distinguish the species and subspecies, and their distributions are given. The larva of L. staudingeri is described.

Mimallonidae of the Caribbean Basin are discussed, with attention primarily given to species endemic to the Caribbean islands and the northern coast of Venezuela. The Caribbean Basin is a political term for tropical regions circumscribed by the Gulf of Mexico. Cicinnus bahamensis sp. n. is described from the Bahamas, the first species of Mimallonidae from this country. The Cuban species Cicinnus packardii (Grote, 1865), the closest relative of C. bahamensis sp. n., is figured and compared. A third, similar, species from northern coastal Venezuela, C. falcoargenteus sp. n., is described and compared to the previous two species.

The holotypes of Arhodia egenaria Walker, 1866 and Cicinnus primolus Schaus, 1928, syn. n., were examined. Both names are junior synonyms of C. melsheimeri (Harris, 1841). Cicinnus melsheimeri (as Perophora egenaria), sensu Hampson, 1904, is a misidentification of C. bahamensis St Laurent & McCabe, 2016.
