Abstract
Bembidion lampros and B. properans possess a similar karyotype with the same chromosome number and sex determination type: .male. 2n = 22A + XO; .female. 2n = 22A + XX. Only slight differences in the karyotype occur between the two species: (1) the X chromosome is metacentric in B. lampros and submetacentric in B. properans, and (2) B. lampros shows the presence of one pair of submetacentric autosomes, not observed in the other species.
