Karyotypes of 15 species of the Acheilognathine fishes were studied using chromosomes of kidney, liver and spleen cells prepared by the air drying technique. The fishes were classified into three groups. The first group possessed 48 chromosomes with the following kinetochore positions; median (m, 4 or 5 pairs), submedian (sm, 9 or 10 pairs), subterminal, terminal and terminal sensu stricto (st, t and T, 10 pairs). The second group contained 44 chromosomes, 6 or 7 pairs in the m-position, 7 or 8 pairs in the sm-position and 8 pairs in the st, t and T-positions. The third group possessed 46 chromosomes, 2 pairs in the sm-position and 21 pairs in the st, t and T-positions. In the first group were Acheilognathus lanceolata, A. limbata, Rhodeus ocellatus ocellatus, R. ocellatus smithii and Tanakia tanago, in the second group A. cyanostigma, A. moriokae, A. tabira tabira, subspecies I and II (I; Akahire-tabira, II; Senboshi-tabira), A. rhombea, A. Longipinnis, and Pseudoperilampus typus, in the third group Rhodeus atremius and R. suigensis. Sexual heteromorphism or intraspecific polymorphism of the chromosomes was not observed in any species studied.
