The presence of Schendyla armata is of some interest. This species is tied to
      Mediterranean forest  (  Quercus ilex,  Q.  su ber),  an d  i t  is  present in southern
      France, Sardinia, Tuscany and Lazio.  In these iatter two Italian regions, it has
      been  reported  oniy on singie  records  at iow aititude  iocaiities,  Prato  and
      Tuscania respectively.
        Among the relatively common species is Eupolybothrus nudicornis. lt is aiso
      a thermophilous species, found in Malta, North Mrica, Spain (but the data
      needs to be confirmed), southern France, Corsica and in Itaiy, where it is dis-
      tributed in the western Alps,  Ligurian Apennines, aiong the whoie peninsu-
      ia (excluding the south-eastern regions), in Siciiy and in Sardinia. In the cen-
      trai Apennines, E.  nudicornis is  especially frequent in open habitats, mostly
      at 500-1,800 m above sea ievel and often characterize the high elevation grass-
      iand centipede communities (1,800-2,000 m)  as,  far exampie,  on the Laga
      and Simbruini-Ernici Mountains and on the Gran Sasso massif.
         Henia vesuviana also belongs to the group of species of western distribution.
      I t is present throughout western Europe, as far east as Romania; it is synanthro-
      pous in centrai Europe, uncertain records are from North Mrica and it has been
      introduced in North America.  It is ve1y common throughout continental and
      insuiar Italy where it is  a forest element, reguiarly present in broad-ieaf forests,
      particuiariy in the oakwoods. In the studied area, it is  present in the forest for-
      mations up to  l ,400 m elevati o n, but rarely encountered at higher elevations.
         Lithobius infossus is also part of this group. lt is the oniy Tyrrhenian endem-
      ie species  reported in the studied area.  This species is  essentialiy inhabiting
      thermophiious  and thermomesophiious forest  formations.  lt is  present in
      Liguria,  aiong  the  ltaiian  peninsuia excluding  the  south-eastern  areas,  in
      Sardinia and Siciiy. I t is aiso known from Lombardy and Veneto, where per-
      haps it has been introduced.

      Southern component

         Nine species with Mediterranean sensu stricto chorotype are included in this
      group. Two species are more or iess widely distributed throughout Itaiy with
      the exclusion of the Alps an d the south-eastern regions, Himantarium gabrielis
      and Stigmatogaster gracilis.  H  gabrielis,  tendentially thermophiious, is  found
      in a wide variety of habitats in Italy, from open to arbustive and forest habi-
      tats.  In the centrai Apennines it coionizes mostly oakwoods but sometimes
      other typoiogies of forests, such as  bee2hwoods, both those at ordinary eleva-
      tions in the Anti-Apennines (Lepini and Ausoni-Aurunci) and in the western
      Apennines mountains chains (Sabini and Simbruini-Ernici), and those at iower
      elevations of the Lazio reliefs  of volcanic origin.  S.  gracilis is  frequent in the
      broad-ieaf forest formations.
