A short interspersed repeat (SINE) in the two sibling species Chironomus pallidivittatus and Chironomus tentans is described. It is present at many sites in the genome and is surrounded by 10 to 14 bp target site duplications. It consists of two sequence modules in different numbers and variable order relative to each other and often has large inversions of different sizes at one end. One of the modules contains pol III promoter consensus sequences. This SINE, nevertheless, is likely to have been dependent on an outside promoter for its formation. It is therefore interesting that both modules start with a 22 bp region with striking similarity to the R2 insertion site in the preribosomal gene of insects. We suggest that this type of SINE, termed Cp1, was formed after a series of events among which the first step was the retroposition of a tRNA gene into the R2 site in the preribosomal gene by the R2 coded protein. The final step is likely to have been due to retroposition from this site.
