A new species of the genus Actinopus Perty, 1833, belonging to the cucutaensis group, is described from Colombia. The new species, Actinopus embera sp. nov., was discovered in the departments of Córdoba, Bolivar, Sucre, and Atlántico, located along Colombia’s Caribbean coast, and is readily distinguished by genital organ morphology. Additionally, we report a possible case of phoresis between a mite of the family Acaridae Latreille, 1802 and a female and three immature specimens of Actinopus embera sp. nov. from one of the type localities (Tiquisio, Bolí var). Finally, based on prior evidence and the events leading to the destruction of the type material, we propose Actinopus cucu taensis Mello-Leitão, 1941 as a species inquirenda.
