In the present study, the chromosomes of a predatory rove beetle Paederus littoralis were studied from Jammu region of outer Himalayas. These beetles are also potential bio-control agents in suppressing the populations of cereal aphids. The diploid chromosome number was found to be 2n=32 including 22 metacentric, 3 submetacentric, 6 subtelocentric and 1 telocentric chromosomes. The sex chromosomes (Xy_p) included submetacentric X and telocentric y chromosome. Meiotic observations comprised diplotene, diakinesis and metaphase-I. The study is helpful in solving taxonomic problems with in the family Staphylinidae and it authenticates the existence of this particular species through chromosomal data. https://www.biotech-asia.org/vol15no2/karyotypic-and-morphometric-analysis-of-a-predatory-rove-beetle-paederus-littoralis-coleoptera-staphylinidae-from-jammu-region-of-outer-himalayas-india/ Chromosomes; Diplotene; Metacentric; Paederus
