Chromosome numbers and karyotypes of Cyprinid fish Alburnoides bipunctatus (Bloch, 1782) from the River Tigris were determined by the chromosome preparation technique from uncultured kidney cells. The diploid chromosome number 2n=50, was composed of 8 pairs of metacentric, 11 pairs of submetacentric and 6 pairs of subtelo-acrocentric chromosomes (NF=88). Sex chromosomes were not determined in the this species. The results were briefly discussed with other, previously conducted studies.

So far, only about 400 species, subspecies, and chromosome races of 15 subfamilies of Tettigoniidae have been studied karyologically, this constituting about 7% of all described species in this group. An attempt was made to establish the basic diploid chromosome numbers of Tettigoniidae and, considering chromosome number, morphology, and the sex determining mechanisms, to suggest how karyotype evolution in the particular subfamilies could have occurred.
