The present paper discusses about the distribution of orthopterans endemic to Italy. This country is located in the centre of the Mediterranean Basin and its palaeo-geographical origins are owed to complex natural phenomena, as well as to a multitude of centres-of-origin, where colonization of fauna and flora concerned. Out of 382 Orthoptera taxa (i.e., species and subspecies) known to occur in Italy, 160 (41.9%) are endemic. Most of them are restricted to the Alps, the Apennines or the two principal islands of Italy (i.e., Sardinia and Sicily). In addition, lowland areas in central-southern Italy host many endemic taxa, which probably originate from the Balkan Peninsula. In Italy, the following 8 genera are considered endemic: Sardoplatycleis, Acroneuroptila, Italopodisma, Epipodisma, Nadigella, Pseudoprumna, Chorthopodisma and Italohippus. Moreover, the subgenus Italoptila is endemic to Italy. For research regarding endemism, Orthoptera are particularly interesting because this order comprises species characterized by different ecological traits; e.g., different dispersal abilities, contrasting thermal requirements or specific demands on their habitats. The highest percentage of apterous or micropterous (35.3%) and brachypterous (16.2%) endemic taxa live in the Apennines, which are among the most isolated mountains of the Italian Peninsula. Finally, some endemic species are endangered at the European scale.

Abstract
The present paper discusses about the distribution of orthopterans endemic to Italy. This country is located in the centre of the Mediterranean Basin and its palaeo-geographical origins are owed to complex natural phenomena, as well as to a multitude of centres-of-origin, where colonization of fauna and flora concerned. Out of 382 Orthoptera taxa (i.e., species and subspecies) known to occur in Italy, 160 (41.9%) are endemic. Most of them are restricted to the Alps, the Apennines or the two principal islands of Italy (i.e., Sardinia and Sicily). In addition, lowland areas in central-southern Italy host many endemic taxa, which probably originate from the Balkan Peninsula. In Italy, the following 8 genera are considered endemic: Sardoplatycleis, Acroneuroptila, Italopodisma, Epipodisma, Nadigella, Pseudoprumna, Chorthopodisma and Italohippus. Moreover, the subgenus Italoptila is endemic to Italy. For research regarding endemism, Orthoptera are particularly interesting because this order comprises species characterized by different ecological traits; e.g., different dispersal abilities, contrasting thermal requirements or specific demands on their habitats. The highest percentage of apterous or micropterous (35.3%) and brachypterous (16.2%) endemic taxa live in the Apennines, which are among the most isolated mountains of the Italian Peninsula. Finally, some endemic species are endangered at the European scale.File | Dimensione | Formato | |
