Chromosomes of Libellago lineata lineata (Chlorocyphidae: Odonata)

Linear characterization and course of meiosis in the zygopteran Libellago lineata lineata of (Chlorocyphidae) are described by conventional staining, C-banding, silver nitrate staining and sequence specific staining. There are two complements n=12 and n=13, without m chromosomes. Increase in chromosome number is due to the fragmentation of medium sized autosome pair. Dark terminal C-bands are present on 9 autosomal bivalents, while remaining 3 bivalents and X chromosome show less amount of C-heterochromatin; 10 autosomal bivalents show terminal NOR-bands; while X chromosome is NOR-negative. All the autosomes and X chromosome possess less intense DAPI and bright CMA₃ signals, which indicate complement is rich in GC rich regions than AT rich regions.
