a smaller percentage, slightly greater than 25%, of elements with a wide dis-
tribution in the Mediterranean basin, mostly belonging to the Mediterranean
sensu stricto chorotype (9 species), a few W-Mediterranean (6 species), and
only one E-Mediterranean; this component, of which the geophilomorphs
are the majorportion (60%), is mainly represented in the flatlands and hilly
areas along the Adriatic and Tyrrhenian side, in particular the Tuscan
Maremma an d T alfa Mountains.
Thus it should be possible to recognize in the centipede fauna as well those
four components (eastern, western, southern and northern), not only in qual-
ity but also, as we will see, in quantity, already recognized by Ruffo (1971) for
the fauna of central Apennines in general. Each of these four components is
discussed below.

Eastern component

Among the species with an eastern geographic distribution, which is the less-
er component of the centipede fauna of the area, only Pleurolithobius patriarchalis,
