present a European distribution, what has been pointed out by González et al. (1987). European
species are dominant in northern and central basins and in contrast, southern basins present a
higher number of species distributed also in North Africa. Southern basins present the highest
proportion of endemic species, with a mix of species widely distributed around the Iberian
Peninsula and those exclusive from the Baetic-Rift area. Our results emphasized the importance
of southern basins as a speciation area for several groups of invertebrates (Ruiz et al., 2001),
which was independent from those that took place in the northwestern areas of the Hesperic
Massif (González et al., 1987).
A total of 12499 larvae, 177 pupae and 261 adults from 169 sites have been identified in our
study. From the records presented here we extend the distribution areas of some species,
confirm the presence of some others and point out several relevant taxonomic information for
further studies. However, more investigations should be performed to ensure the identity of
several species (e.g., H. gr. instabilis called H. sp1) and to describe larvae specimens of some
species (e.g., H. acinoxas, A. incertulus, A. mortoni).
