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

Abstract

A revision of mapping of main and alternative banding sequences in chromosome III (EF) has been made for 14 species of the Chironomus plumosus 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 Ch. plumosus group in comparison with basic banding sequences of the genus Chironomus is suggested. The presented data indicate that h’pluE2 in arm E and p’borF2 in arm F are the closest to banding sequences of Ch. piger Strenzke, 1959 and thus should be considered the most ancient among banding sequences of chromosome III in the Ch. plumosus group. Phylogenetic relationships of banding sequences of chromosome III are discussed.

Revision of the banding sequence pool and new data on chromosomal polymorphism in natural populations of Chironomus agilis Shobanov et Djomin, 1988 (Diptera, Chironomidae)

“…The revision of mapping of main banding sequences in arms A, B, C, D, E and F was presented by Golygina and Kiknadze previously (2008, 2012, 2018. Revised mapping of these banding sequences is shown on Fig.…”

“…Arm A was monomorphic in all populations with the exception of the Siberian population from the pond on the Eltsovka river where banding sequence p'agiA2 was Keyl (1962), GV -version of mapping in arm E according to Golygina and Kiknadze (2018).…”

“…Arrows indicate centromeric regions. KV -version of mapping in arm E according toKeyl (1962), GV -version of mapping in arm E according toGolygina and Kiknadze (2018).…”

“…The second one is done according to revised mapping of Ch. plumosus made byGolygina and Kiknadze (2018) (marked as GV).…”
