Abstract
Ten microsatellite loci were isolated and characterized for Stys's bush-cricket, Isophya stysi Cejchan (Orthoptera: Tettigoniidae), an endemic Orthoptera species to the Carpathian Basin, using an enriched genomic library procedure. The polymorphism of these loci were tested in two populations of I. stysi, and the number of alleles per locus varied from 4 to 16. The expected and observed heterozygosities ranged from 0.612 to 0.925 and from 0.625 to 1.000, respectively. The interspecific applicability of these microsatellites was evaluated by amplification in 20 related species: Isophya camptoxypha, Isophya sicula, Isophya ciucasi, Isophya pienensis, Isophya harzi, Isophya kraussii, Isophya zubovskii, Isophya rectipennis, Isophya modesta, Isophya longicaudata, Isophya dobrogensis, Isophya hospodar, Isophya speciosa, Isophya modestior, Poecilimon fussii, Poecilimon affinis, Polysarcus denticauda, Barbitistes constrictus, Leptophyes discoidalis, Phaneroptera falcata. All primer pairs for the 10 loci yielded successful amplifications in at least one other taxon from the Isophya genus. This set of microsatellite loci would be useful for genetic studies in I. stysi and other species of the genus Isophya.
