Abstract

A catalogue of Orthoptera species collected during 1997 from isolated islets of the northern Dodecanese archipelago, Greece, is presented. Information on related taxonomical aspects and ecological parameters is also given.

  • Orthoptera are one of the most thoroughly studied invertebrate taxa within mainland and insular Greece: approximately 150 titles, covering every major geographical division of the country, are reported to have been published up to 1984 (Willemse, 1984), with a few new papers emerging since

  • A few Orthopteran taxa (Duroniella, Melanogryllus desertus, Eumodicogryllus) previously reported from larger insular and continental land regions in the Aegean Sea can occur in small isolated spots within the archipelago. It is not known whether the paleogeographical pattern of island isolation history or any contemporary ecological processes, for example successful immigration, better explain current Orthoptera ranges in the Aegean

Summary

Introduction

Orthoptera are one of the most thoroughly studied invertebrate taxa within mainland and insular Greece: approximately 150 titles, covering every major geographical division of the country, are reported to have been published up to 1984 (Willemse, 1984), with a few new papers emerging since . Since the 50s, published information tends to fit into a larger geographical context or refers only to certain Orthopteroid taxa (as in Willemse, 1982; Baccetti, 1992; etc.). This paper aims to present information on the Orthoptera species collected from some of the smallest and least accessible islands of the northern part of the Dodecanese archipelago from which to my PAPAPAVLOU knowledge, there are no other published records up to this moment (Fig. 1). For several of these taxa the taxonomic status remains dubious and the corresponding biogeographic knowledge is only based on scarce data. It is hoped that the collected material, apart from providing new faunistic records, may help in elucidating ambiguous past information on systematics, biogeography and perhaps ecology of certain taxa in the region
