25. Maiella (Mai): between the valley of the Pescara River to the north, the
valley of the Gizio River to the west, and the valley of the Sangro River to the
south; Morrone Mountain was also included in this sector.

Hilly Adriatic sector
26. Hills of the Adriatic site, induding Conero Mountain (Adr): from the
valley of the Foglia River to the north to the valley of the Fortore River to the
south, from the eastern slopes of the orientai Apennines chains (Umbrian-
Marchigian Apennines, Sibillini and Laga Mountains, the Gran Sasso, and
Maiella) to the Adriatic sea coast.

RESULTS

Faunistic analysis

In the studied area 67 species of centipedes were found: l Scutigeromorpha,
31 Lithobiomorpha, 8 Scolopendromorpha, and 27 Geophilomorpha. Two
species were introduced (Lamyctes emarginatus, Lithobius peregrinus), and three
are of uncertain taxonomic status (Lithobius biporus, Schendyla aternana, S.
viridis). The geophilomorph schendylid Schendyla armata (Brolemann, 1901)
recorded in Lazio for the fìrst time (province of Viterbo, surroundings of
Tuscania, Quercus suber forest, 42°25'29" N, 11 o54'20" E, 13.IV.2006, S.
Pieri leg., l specimen, M. Zapparoli det., collection M. Zapparoli) must to be
added to the 67 species already reported in Zapparoli (2006a) except
Stenotaenia linearis C.L. Koch, 1835 (= Geophilus linearis C.L. Koch, 1835 not
present in Centrai Italy according to Bonato and Minelli (2008). The list of
species, each with the geographic sectors in which it is found and its assigned
chorotype indicated, is reported in T ab. I.
Overall there is a relatively rich centipede fauna in the studied area, whose num-
ber of species corresponds to 41.9% of those reported in Italy (160; Zapparoli
an d Minelli, 2006) an d to 13.8% of those present in Europe ( 486; Zapparoli an d
Minelli, 2006). Such richness also emerge from comparisons with other areas that
differ in their geographic extension, environmental heterogeneity and degree of
fa unisti c knowledge, both Apenninic, like Ligurian Apennines, T uscan-Emilian
Apennines, the southern Apennines, with 50-60 species ( Chelazzi, 1970; Minelli
and Zapparoli, 1985; Zapparoli, 1986; Zapparoli and Minelli, 2006), and Alpine,
like the south-eastern Alps and 't:he western Alps, both with 76 species, and the
Ligurian Alps, with 52 species (Minelli and Zapparoli, 1985, 1992; Zapparoli,
1989; Minelli, 1991). Moreover, the number of reported species is higher than
that of Sardinia and Sicily (49 and 47 respectively: Foddai et al., 1995, 1996;
Zapparoli and Minelli, 2006).
