The genera Badelina Thomson, 1880, Balsameda Thomson, 1880, Guatemalica Neervoort van de Poll, 1886, and Heterocotinis Martínez, 1948 are reviewed. Redescriptions, diagnoses, distributions, and illustrations of all species in each genus are provided. Balsameda monzoni Ratcliffe and Balsameda porioni Ratcliffe are described as new species from Guatemala and Mexico, respectively. Gymnetis marginicollis Burmeister, 1842 (formerly Guatemalica marginicollis) was recently transferred to Amithao, and Gymnetis luctuosa Bourgoin, 1916 is not in the genus Guatemalica but in a yet-to-be determined species of Gymnetis MacLeay. Gymnetis smaragdinea Gory and Percheron, 1833 and Cotinis nitidicollis Moser, 1907 are placed in new junior synonymy with Heteroconitis terminata (Gory and Percheron, 1833).
