Abstract
The section Uniolae of the genus Tribolium Desv. comprises four specie s, namely T. alternans (Nees) Renv., T. amplexum (Nees) Renv., T. brac hystachyum (Nees) Renv. and T. uniolae (L. f.) Renv. Tribolium alterna ns, T. amplexum and T. uniolae are morphologically similar and form a hybrid swarm. Thus, only two species should be recognized, namely T. b rachystachyum and a T. uniolae hybrid swarm. Diploid, tetraploid and h exaploid specimens have been observed in the T. uniolae hybrid swarm, whereas all the T. brachystachyum specimens were tetraploid. Segmental alloploidy, tending towards alloploidy, is present in both species.
