North-Western Palaearctic species of Pristiphora (Hymenoptera, Tenthredinidae)

Abstract

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).

Sawflies of the Bakony Mountains and the Balaton Uplands (Hymenoptera: Symphyta)

“…For identification, Zhelochovtsev's (1988) work on the sawflies of the European part of the former USSR was consulted. We also used some recent revisions and works to make the identifications even more precise (Achterberg and Aartsen 1986, Blank & Ritzau 1998, 2006, Haris and Gyurkovics 2014, Koch 1988aand b, Prous 2012, Prous et al 2017, Taeger 1987and Taeger 2015.…”
