Also, some species, like Medon burdigalensis Coiffait and M aquitanicus Coiffait, had never been recorded again after their description, although they had been de- scribed from regions where the presence of local en- demics is unlikely; consequently, the absence of records could not be put down to extremely restricted distribu- tions. These considerations, as well as the difficulty en- countered when trying to identify Medon material from the study area suggested that the previous taxonomic concept of the Medon fauna of the Western Mediterra- nean was at least in part inadequate and eventually initi- ated the present revision. >aW\.
