Objective:

to determine the degree of variation of the structural components of the left tegmina in relation to the right tegmina, and how their pattern of variation is within and among taxa of Tettigoniidae.

Methods:

A total of 192 specimens from the Colombian Andean Region, the Amazon, and the Brazilian Atlantic Forest were dissected. Th e tegminas were photographed and six anatomical points were located on them, which were used to perform ANOVA Procrustes morphometric analyzes and main components obtained from the matrices of the covariance of the symmetric and asymmetric effect.

Results:

Asymmetry is highly significant both for the superfamily and the subfamilies level. However, the group differentiation by side was very significant for the family and in the subfamilies except for Pseudophyllinae.

Conclusions:

Each subfamily and most of the tribes studied present specific morphological patterns that can even be used as taxonomic characters.
