Chironomus polonicus sp. n. (Diptera: Chironomidae) from southern Poland

摘要

The paper describes larval, pupal and adult morphology as well as the karyotype of Chironomus polonicus sp. n. from southern Poland. The material has been obtained from reared egg masses collected in Boleslaw pool, near Krakow. The species belongs tothe pseudothummi cytocomplex with 2n = 8 and chromosome arm combinations AE, BF, CD, G. Several homozygous inversions distinguish arm A of the new species from that of C. pseudothummi Strenzke. Arm F is similar to that of C. aprilimis Meigen and differsfrom it by few steps of homozygous inversions. Few morphological differences in the pupa and adult are also presented.
