Abstract

Calliptamus barbarus (Orthoptera: Calliptaminae) is a most polymorphic species with one (1S) or three (3S) femoral spot. In the previous studies, comparisons of the two forms were made. In previous studies, different authors have attempted to compare the two forms of this species based on the morphology of the inner surface of the posterior femur (red or orange), classical morphometry, isolation reproductive, sound production, enzymatic and biochemical characters and recently a phyllogenic study based on the use of mitochondrial DNA. In order to distinguish these forms between them we conducted a landmark-based geometric morphometric analysis on right and left elytra via the Generalized Procustes Analysis (GPA). This method allowed us to quantify the asymmetry of the elytra and identify shape changes between the two forms. It is performed by three mathematical operations: rotation, translation and scaling using the TPS software. Eleven landmarks were chosen at vein intersections. The obtained results show that the landmarks 4, 5 and 6 had  low  amounts of variability, but in general the displacement of  landmark 11 on 1 and 3S form of C. barbarus is not very important. Thus the modifications of the wing shape between forms are slight. The effect of sex (male, female) and chromatic polymorphism on the wing asymmetry were not significant. This means that there is only one kind of asymmetry – a fluctuating asymmetry, and it is entirely due to development stress..
