C-banded karyotypes of some dragonfly species from Russia. II. The families Cordulegasteridae, Corduliidae and Gomphidae.
The C-stained karyotypes of five species of three dragonfly families from Western Siberia and Kunashir Island have been analysed. Gomphus epophtalmus Sel., G. vulgatissimus (L.), Nihonogomphus ruptus (Sel. et Hag.) (Gomphidae), and Anotogaster sieboldii (Sel.) (Cordulegasteridae) showed usual character of C-heterochromatin distribution, all chromosomes have terminal C-bands. Somatochlora graeseri Sel. (Corduliidae) has unique for dragonflies type of terminal C-blocks on autosomes. Three pairs of autosomes have the very large heterochromatic blocks, other chromosomes, including the X, have no C-band.
