Genetic variability of two ecomorphological forms of Stenus Latreille, 1797 in Iran, with notes on the infrageneric classification of the genus (Coleoptera, Staphylinidae, Steninae)
In this study, the genetic diversity of Iranian populations of two widespread Stenus species representing two ecomorphological forms, the “open living species” S. erythrocnemus Eppelsheim, 1884 and the “stratobiont” S. callidus Baudi di Selve, 1848, is presented using data from a fragment of the mitochondrial COI gene. We evaluate the mitochondrial cytochrome oxidase I haplotypes and the intraspecific genetic distance of these two species. Our results reveal a very low diversity of COI sequences in S. erythrocnemus in contrast to S. callidus. Moreover, the COI based phylogeny of a selection of Iranian Stenus support the monophyly of some species groups of Stenus proposed by Puthz (2008) and contradicts the traditional infrageneric classification.
