TL;DR: Standard maps of polytene salivary gland chromosomes of black fly species Simulium (Simulium) singtamense have been prepared and revealed normal simuliid complement of n=3 chromosomes.
Abstract: Standard maps of polytene salivary gland chromosomes of black fly species Simulium (Simulium) singtamense have been prepared. It revealed normal simuliid complement of n=3 chromosomes. Two homologues of each polytene chromosomes are tightly synapsed and are provided with identifiable centromeres. First two chromosomes are metacentric while the third one is submetacentric. Characteristic landmarks of polytene chromosomes such as Balbiani Ring, nucleolar organiser, puff and characteristic banding patterns have been described and compared with those of congeneric species.
