Cytogenetic characteristics of species of the Chironomus genus (Diptera, Chironomidae) from Lake Łuknajno Biosphere Reserve (northwest Poland)

Abstract

The cytotaxonomic characteristics of two species of the Chironomus genus from Lake Łuknajno (northwest Poland) were determined: Chironomus nuditarsis Strenzke, 1959 with the chromosome arm combinations of AB, CD, EF, and G (the "thummi" cytocomplex), and Camptochironomus tentans (Fabricius, 1805) with the chromosome arm combinations of AB, CF, DE, and G. A heterozygous inversion in arm F of the Chironomus nuditarsis chromosomes was detected. The polymorphism of Camptochironomus tentans as a homozygous inversion in arms A and E and a heterozygous inversion in arm F were revealed. 1 ijpb@uwm.edu.pl 2 michailova@zoology.bas.bg

The first record of Chironomus nuditarsis Keyl, 1961 from Sevan Lake (Armenia) confirmed by morphology, karyotype and COI gene sequence

“…Later, in an article by Jabłońska-Barna and Michailova, the species was named Ch. nuditarsis Strenzke, 1959 ( Jabłońska-Barna and Michailova 2009 ). In recent works by Kiknadze et al ( Kiknadze et al 2016 ) and Karmokov ( Karmokov 2020 ) the species is named Ch.…”

“…The studied species Ch. nuditarsis has a wide Palearctic range; therefore it is a convenient object for studying the chromosomal divergence of populations and species ( Polukonova et al 2005a , 2005b ; Kiknadze et al 2006 ; Jabłońska-Barna and Michailova 2009 ; Kiknadze et al 2016 ; Karmokov 2020 ).
