ABSTRACT

Taxonomic, nomenclatoral, and comparative morphological studies of Cycloneda Crotch are reviewed. The genus is diagnosed and compared to both related and superficially similar taxa. Pseudadonia Timberlake is recognized as a junior synonym (n. syn.). The species composition of the fauna is delineated, but the need to re-examine species limits and nomenclatoral priorities is stressed. New synonyms are proposed for two species of Cycloneda occurring in North America: Coccinella krikkeni Iablokoff-Khnzorian, reported from India, and Cycloneda atra Casey (of unknown origin) are new junior synonyms of Cycloneda munda (Say); Cycloneda hondurasica Casey (Honduras) and Coccinella reflexa Germain (Chile) are new junior synonyms of Cycloneda sanguinea (Linnaeus). Adalia galapagoensis Van Dyke is transferred to the genus Cycloneda (Cycloneda galapagoensis, n. comb.) and identified as a close relative of Cycloneda sanguinea. Cycloneda sanguinea caymana Chapin is elevated to full species status (Cycloneda caymana, n. status). A new key to species of North American Cycloneda is provided.
