Amphinemura palmeni is a valid Holarctic stonefly species (Plecoptera: Nemouridae)

Abstract

The taxonomic status of Amphinemura palmeni, a rare stonefly from northern Fennoscandia, was re-evaluated in a morphological study combined with analyses of mitochondrial COI and nuclear 28S sequences. Taxon sampling included A. standfussi, with which A. palmeni has been confused, the Nearctic A. linda and seven other Amphinemura species. Amphinemura palmeni is confirmed as a valid species, and A. norvegica and A. linda identified as junior synonyms. The species is illustrated with line drawings, photographs and SEM micrographs. Its COI haplotype diversity is compared with the intraspecific diversity in other stonefly species. © 2012 Magnolia Press.
