Popis: Phylogenetic morphological, and molecular analysis of lumpsuckers of the family Cyclopteridae is carried out. The cladograms reveal the validity of three subfamilies within the family Cyclopteridae: Cyclopterinae, Aptocyclinae, and Eumicrotrematominae. Five valid genera (Cyclopterus, Aptocyclus, Cyclopsis, Lethotremus, and Eumicrotremus) are revealed, and the genus Cyclopterus is accepted as the most generalized within the family Cyclopteridae. The genus Lethotremus is separated from the species of the genus Eumicrotremus, and, thus, the generic status of the former genus is restored. The taxonomic position of E. soldatovi is discussed. Based on the presence of a large number of monotypic genera among generalized clades of lumpsuckers, they could represent the remains of the former widely distributed fauna with a weak development or absence of external armament. The forms of the genus Eumicrotremus with a good armament represent a comparatively young group of weakly differentiated species. Several heterochronies of the paedomorphic and peramorphic types are revealed in the evolution of the family Cyclopteridae.
