4. Conclusions and final remarks

With the first report on Altica carduorum Meneville-Guérin, Chaetocnema obesa (Boield-
ieu), Longitarsus helvolus Kutschera, L. monticola Kutschera, L. rectilineatus (Foudras),
Mniophila muscorum (Koch) and the alien species Epitrix hirtipennis (Melsheimer), 160
species of flea beetles from Sicily are currently known. The occurrence of Longitarsus mem-
branaceus (Foudras) is considered questionable and will need further confirms. The Alticini
species of Sicily constitute about 45% of the whole ltalian flea beetle fauna (Biondi 2013).
Eighteen different chorotypes are represented; 53% of the total species show a widespread
distribution in the Palaearctic Region (PAL s.I.), including mainly the Euro-Mediterranean
chorotype (25 species; 15.6% of the total) (see Figs. l and 2).

Particularly important results is also the contribution of the Mediterranean compo-
nent (MED s.I.: 25% of the total), with the Mediterranean chorotype (20 species), West-
Mediterranean chorotype (15) and North-African chorotype, this last represented by 5
species, Dibolia maura Allard, Longitarsus albus (Allard), Longitarsus scaphidioides
Abeille, Phyllotreta nitidicollis Weise and Psylliodes heikertingeri Jacobson, shared with
Mediterranean Africa and mainly occurring in the southern-eastern area of Sicily. Signifi-
cant are also the European (21 species) and South-European (9) chorotypes, with species
occurri ng mainly in the Apennine area of northern Sicily.

As for the endernicity, Sicily has 14 subendernic species of Chrysomelidae, amounting
to 62.5% of the entire ltalian endemie leaf beetle component, but no strictly flea beetle
endemie taxa is present, apart, perhaps, from Aphthona sicelidis (Biondi et al. 2013).
However, four species of Alticini - Longitarsus laureolae Biondi, Psylliodes caneparii
Leonardi, P. leonhardi Heikertinger and P. ruffoi Leonardi - show a distribution including
only Southern Apennines and North-Western Sicily (SISA), due surely to the position
of the island that reflects its close geographic proximity and ecological continuity with
