The two species, Isopsera sp. and Letana atomifera belonging to the family Locustidae, a group of long-horned grasshoppers, were found to have unusual sex chromosome constitutions namely, neo-X+neo-Y and X1X2 +neo-Y respectively, in the male individuals. At the present status of our knowledge of chromosomes in the Locustidae, it is impossible to draw any conclusion regarding the nature of the probable evolutionary pathway in these insects.
