Amphibolips is currently divided into two species-groups, clearly differentiated by adult and gall morphology. The ‘niger’ group of Amphibolips species is revised. This complex includes eight species: A. gumia Kinsey, A. jubatus Kinsey, A. elatus Kinsey, A. maturus Kinsey, A. nebris Kinsey, A. niger Kinsey, A. pistrix Kinsey and A. ufo Cuesta-Porta & Pujade-Villar sp. nov. We provide descriptions of new species and re-descriptions of known species, diagnoses, keys to complexes and species. The possibility of the ‘niger’ complex belonging to a new genus is also discussed.
