Chironomus luridus Srenzke View in CoL

The chromosome set is 2n = 8. Chromosome AE is submetacentric, chromosomes CD and BF are metacentric, chromosome G is telocentric. Near to the centromere region of chromosome G there is puff. Two BRs are close to each other. In the middle of the chromosome G there is a constriction surrounded by thick dark bands, a marker of the species ( Fig. 17 View FIGURE17 ). The “basic” patterns in A2.2 are in inverted state in comparison with the standard species, C. piger . Twenty-two larvae were analyzed .

Collection sites: Sofia: South Park ; Varna, region St. Konstantin and Elena .
