Chromosomal Rearrangements and Karyotypic Evolution in Decticinae (Orthoptera: Tettigonioidea)

Abstract

The superfamily Tettigonioidea is characterised by a variation in its chromosome numbers that extends over a wide range. This variation is principally caused by chromosomal rearrangements such as centric fusions and pericentric inversions. Thus, the species Metioptera brachyptera has 31 telocentric chromosomes in males (Southern 1967) while M. saussureana has 2n
