“…Seven sequences of four specimens (4b, 9t, DG, DH) newly reported here were obtained from the VoSeq database (Peña and Malm 2012) maintained by Tommi Nyman (University of Eastern Finland). For these four specimens, 810 bp of COI and 997 bp of NaK had been sequenced as described previously (Nyman et al 2006, Leppänen et al 2012.…”

North-Western Palaearctic species of Pristiphora Latreille, 1810 are revised. Altogether, 90 species are treated, two of which are described as new: P. caraganae Vikberg & Prous, sp. n. from Finland and P. dedeara Liston & Prous, sp. n. from Germany. Host plant of P. caraganae is Caragana arborescens Lam. Pristiphora dasiphorae (Zinovjev, 1993) (Haris, 2001) comb. n. Lectotypes are designated for 43 taxa. An illustrated electronic key made with Lucid and a traditional dichotomous key are provided to facilitate identification of the species. Species belonging to the carinata (previously Lygaeotus), micronematica (previously Lygaeophora), and rufipes (also known as thalictri or aquilegiae) groups are not keyed to the species level, because additional research is needed to delimit the species more reliably in these groups. Phylogeny of Pristiphora is reconstructed based on one mitochondrial (COI) and two nuclear (NaK and TPI) genes. Remarkably, around 50-60% (depending on the exclusion or inclusion of the carinata, micronematica, and rufipes groups) of the species cannot be reliably identified based on COI barcodes. Limited data from nuclear genes indicate a better identification potential (about 20% remain problematic).

“…Sequence data were collected from the mitochondrial genes Cytochrome oxidase I (CoI; 810 bp) and Cytochrome b (Cytb; 718 bp), and the nuclear genes Elongation factor-1α (EF-1α; two exons of the F2 copy; 777 bp in all) and Sodium-potassium adenosine triphosphatase (NaK; 997 bp). PCR amplification and sequencing of CoI, Cytb, EF-1α, and NaK were done as described earlier (Nyman et al 2000;Nyman et al 2006;Leppänen et al 2012). New sequences have been deposited in GenBank under accession numbers KJ434795-KJ434930.…”

Recent phylogenetic studies on Nematinae based on DNA sequences have shown extensive incongruencies with current nomenclature of genus-group taxa. Here, we expand previous DNA sequence datasets based on three genes (CoI, Cytb, and EF-1α), to include a fourth (NaK) and more genera. The analyses largely confirm the previous findings, particularly the existence of two well-supported large clades, Euura and Pristiphora, together comprising more than 75% of the species of Nematinae. Basal relationships within these two clades remain poorly resolved, mirroring the difficulties in delimiting genera based on morphology. In addition, a moderately supported small clade, Nematus, is found. The relationships between the Euura, Pristiphora, and Nematus clades are uncertain. Therefore, to stabilize the nomenclature we treat these clades as genera. This taxonomic treatment results in numerous new combinations of species names. The following synonymies are

“…Furthermore, the apparently apically widened sawsheath of the holotype of H. imbrosensis [examined] as drawn by Schedl (1981) is the result of disruption of the valves of the sheath during extraction of the saw. As pointed out by Leppänen et al (2012), the status of some of the Acer-feeding Heterarthrus needs further study, ideally including sequencing of nuclear DNA. † Periclista cretica (Schedl, 1981) Material.…”
