The revision of chromosome III (EF) mapping in (Linnaeus, 1758) group (Diptera, Chironomidae).

A revision of mapping of main and alternative banding sequences in chromosome III (EF) has been made for 14 species of the group. In total, new versions of mapping are presented for 18 banding sequences of arm E and 18 banding sequences of arm F. A new way of tracing the origins of banding sequences in chromosome III of the group in comparison with basic banding sequences of the genus is suggested.

Redescription of larva, pupa and imago male of Chironomus (Chironomus) salinarius Kieffer from the saline rivers of the Lake Elton basin (Russia), its karyotype and ecology.

Cytology and ecology of Chironomus (Chironomus) salinarius Kieffer, 1915 (Diptera, Chironomidae) was examined from material collected in the saline rivers of the Lake Elton basin (Volgograd region, Russia). Larvae of salinarius-type were identified as C. salinarius on the basis of their karyotype.

A revision of chromosome II (CD) mapping in Chironomus plumosus (Linnaeus, 1758) group (Diptera, Chironomidae).

A revision of the main and alternative banding sequences in chromosome II (CD) has been made for all 14 species of the Chironomus plumosus (Linnaeus, 1758)group. A new version of mapping has been suggested for 10 out of 18 banding sequences of arm C and 12 out of 22 banding sequences of arm D. Mapping of 7 banding sequences has been done for the first time according to the Keyl-Devai system.

Karyotypes of Chironomus Meigen (Diptera: Chironomidae) species from Africa.

The karyotypes of six African Chironomus species (Chironomus alluaudi Kieffer, 1913, Chironomus transvaalensis Kieffer, 1923, Chironomus sp. Nakuru, Chironomus formosipennis Kieffer, 1908, Chironomus prope pulcher Wiedemann, 1830, Chironomus sp. Kisumu) were investigated; four of these karyotypes were described for the first time (Chironomus sp.

[Differentiation of chromosome banding sequence pools and genomic DNA in holarctic natural populations of Chironomus entis Shobanov (Diptera, Chironomidae)].

Polymorphism and differentiation of the chromosome banding sequence pools and genomic DNA were studied in three natural populations of Chironomus entis from Europe and North America. These populations showed a moderate level of chromosome polymorphism and high RAPD polymorphism of genomic DNA. The Palearctic and Nearctic populations of this species did not differ significantly in the levels of chromosome and genomic DNA polymorphism.
