Teratodes monticollis

Acridoidea is the largest superfamily of grasshoppers in the order Orthoptera with species found on every continent except Antarctica.[1]

Classification

Orthoptera Species File includes the following families:[1]

Chromosomes

Among the families Acrididae, Ommexechidae and Romaleidae there is reported to be chromosomal stability with a high frequency of species harbouring diploid number (2n) of 23♂/24♀ chromosomes.[2][3] In species of Acrididae and Romaleidae it is common to have acrocentric chromosomes with a fundamental number (FN), i.e. number of chromosome arms, of 23♂/24♀.[3] However, chromosomal rearrangements are frequently found as deviations from the standard acrocentric karyotype. In the subfamily Ommexechinae most species show a unique karyotype (2n = 23♂/24♀, FN = 25♂/26♀) due to the occurrence of a large autosomal pair (L1) with submetacentric morphology.[3] There is some support for 'Mesa's hypothesis' of an ancestral pericentric inversion in the ancestor of Ommexechinae to explain this karyotype variation.[4][5][3][6]
