Abstract

The germ line limited (K) chromosomes of Acricotopus lucidus (Diptera, Chironomidae) were stained for G-banding on gonial mitoses, along with the somatic (S) chromosomes. Nine different types of K chromosomes could be distinguished by the G-banding pattern and other cytological criteria. Various combinations of K chromosomes were found in the complements of different individuals and cells: some Ks were missing and others were present up to as many as five times. No two animals were completely alike in the composition of their gonial chromosome complement. Thus none of the different K types can be essential. These results are discussed in view of the complex chromosome cycle of the Orthocladiinae.
