Abstract(s)
Biometric data of the exuviae of female larvae of the dragonfl y Cordulegaster boltonii collected in Portugal, Spain and
Morocco were analysed to determine whether the size of three exuvial structures measured differed depending on the geographic
localities of the populations. Based on the results recorded for the 16 populations studied, head width was negatively correlated
with latitude and the greatest length of the gonapophysis was recorded for the Iberian populations at the centre of this peninsula.
Multivariate cluster analysis revealed a clear separation of the Moroccan population. A second cluster separated the southernmost
population (Sierra Nevada) from the remaining Iberian populations. Four population groups were distinguished: those located in
watercourses in the north and central area of the Iberian Peninsula, those in Iberian watercourses in the East and Middle South,
the Sierra Nevada and North Morocco. Some of these results coincide with the results of genetic studies of other authors.
