The new genus Huaca is established for a Panamanian species of Anthonomini originally described as Pseudanthonomus curvicrus Champion (the type species of Huaca), and for 25 previously undescribed neotropical Anthonomini: H. apian (Dominica, Puerto Rico, Republica Dominicana, Florida), H. ayacho (Puerto Rico, United States Virgin Islands), H. cajana (Honduras), H. capi (Uruguay), H. cauas (Costa Rica, Mexico), H. cicui (Panama), H. cinca (Brazil, Mexico, Venezuela), H. collana (Cuba, jamaica), H. cuipan (Belize, Guatemala), H. cumpi (Brazil), H. guayra (Florida), H. matoro (Puerto Rico), H. mayu (Mexico), H. mudca (Honduras), H. pacha (St. Christopher), H. payan (Republica Dominicana), H. picas (Mexico), H. puquiu (Republica Dominicana), H. quilca (Trinidad), H. quillo (Puerto Rico), H. quisco (Jamaica), H. sucanca (Brazil), H. turuca (Dominica), H. usno (Mexico, Venezuela), H. uxi (Mexico). Specimens of these species have been collected in association with plants in the families Malpighiaceae, Myrtaceae, Phytolaccaceae, Rhizophoraceae, Rubiaceae and Rutaceae, but developmental sites and immature stages are not known for any of the species. Characters by which the genus Huaca and each of the included species are distinguished are described and illustrated, and a key to the species is presented.
