Gallen i et ABC ABC Fig. 4: G-banded (left) and C-banded (right) X chromosomes of M. savii (A: acrocentric, C: metacentric) and M. brachycercus (B). question of the taxonomic state of populations from different localities of southern Italy and Sicily is still open however. The agreement between karyotypes of specimens from northern and central Italy (Parco Lambro and Monte Cimone) and that of the specimen from Sicily supports the classification suggested by Krapp & Winking (1976) who considered these populations as all belonging to the subspecies M. savii savii. It appears, in this case, that allopatric distribution has not been followed by differentiation at specific level at least in respect of morphological and karyological traits. The presence of specimens with the same karyotype as M. brachycercus at Fiume Freddo (Calabria) confirms the occurrence of this species in the Calabrian peninsula. The X-acrocentric karyotype of the female from Metaponto (Potenza) is similar to that described by Niethammer (1981) for a specimen from Monte Gargano (Foggia). Because of the proximity of the two collecting sites (Fig. 1) it is likely that we are dealing with the same form. Hypotheses on the relationships between the metacentric X chromosome of M. savii and the sub-metacentric X of M. brachycercus were discussed previously (Galleni et al. 1992). A similarity of G-banding pattern between the euchromatic part of X chromosome long arm of M. brachycercus and the whole metacentric X of M. savii was also confirmed in this study (Fig. 4). The acrocentric X chromosome is similar to the metacentric X but it is not possible to resolve the bands to ascertain if a pericentric inversion took place in the X of M. savii generating the acrocentric form. According to the taxonomic revision based on tooth morphology (Brunet-Lecomte 1988) the forms
