Popis: West Indian genera of the flea beetle subtribe Oedionychina Chapuis, 1875 are reviewed. Two new genera and one new species are described: Argusonychis Konstantinov, Van Roie, & Furth gen. nov. with Argusonychis clarki Konstantinov, Van Roie & Furth sp. nov. as the type species (Bahamas); and Ciguapanychis Konstantinov, Van Roie & Furth gen. nov. with Alagoasa bicolor (Linnaeus, 1767) as the type species (Puerto Rico). An illustrated key to the genera found in the West Indies is provided. Each genus is illustrated with images of external and internal morphology, including thoracic structures, metendosternite, and female and male genitalia. Asphaera subfasciata Clark, 1860 is designated as the type species for Asphaera Duponchel & Chevrolat in d’Orbigny, 1842. The genus Ptena Chevrolat, 1836 is considered a long-overlooked senior synonym of Asphaera; the use of Asphaera is maintained. The lectotypes are designated for: Chrysomela albicollis Fabricius, 1787, Oedionychis crucipennis Suffrian, 1868, and Haltica decipiens Klug, 1829. Pleurasphaera Bechyné, 1958 is recognized as an objective junior synonym of Litosonycha Chevrolat, 1836 since these two generic names share the same type species, Haltica decipiens Klug, 1829. Oedionychis punctipennis Blake, 1971 is synonymized with Alagoasa sharpi (Jacoby, 1897). The following 17 new combinations are proposed: Alagoasa lunata (Fabricius, 1801), Alagoasa sharpi (Jacoby, 1897), Alagoasa smithi (Jacoby, 1897), Argusonychis megalopia (Blake, 1939), Argusonychis orientensis (Blake, 1959), Argusonychis zayasi (Blake, 1959), Asphaera amplilimbata (Blake, 1959), Asphaera cristalensis (Blake, 1959), Ciguapanychis bicolor (Linnaeus, 1767), Ciguapanychis dimidiatus (Olivier, 1808), Ciguapanychis fasciatus (Fabricius, 1798), Ciguapanychis jamaicensis (Jacoby, 1894), Ciguapanychis pseudofasciatus (Blake, 1940), Ciguapanychis viridipennis (Blake, 1971), Kuschelina pseudothoracica (Blake, 1945), Omophoita turquino (Zayas, 1988), and Walterianella gurneyi (Blake, 1968). The following three species are removed from synonymy and restored to species status as new combinations: Ciguapanychis cinctus (Olivier, 1808), Ciguapanychis lantanus (Blake, 1928), and Ciguapanychis purpurellus (Blake, 1940).
