North-Western Palaearctic species of Pristiphora (Hymenoptera, Tenthredinidae) Author Prous, Marko Author Kramp, Katja Author Liston 1, Veli VikbergAndrew text Journal of Hymenoptera Research 2017 59 1 190 http://dx.doi.org/10.3897/jhr.59.12565 journal article http://dx.doi.org/10.3897/jhr.59.12565 1314-2607-59-1 598C5BB321364D91B522FA14D8874A52 Pristiphora groenblomi (Lindqvist, 1952) Figs 10, 211 Lygaeonematus (Lygaeotus) groenblomi [sic!] Lindqvist, 1952: 101. Note. The spelling groenblomi is in predominant usage, not gronblomi, which would be correct according to Article 32.5.2 ( ICZN 1999 ). Following Article 33.3.1, the predominantly used spelling is maintained. Holotype ♀ (DEI-GISHym31602) in MZH, examined. Type locality: Luumaeki , South Karelia, Finland. Similar species. Species limits in the carinata group are still unclear. Genetic data. Based on COI barcode sequences, specimens of the carinata group are divided between four BIN clusters (BOLD:AAF4995, BOLD:ABU8603, BOLD:ACL1744, BOLD:ACL1745), which form a monophyletic group (Fig. 5). Minimal distances between these clusters are 1.2%-4.48%. Because of unresolved taxonomy, it is not yet clear how different species are divided among these BIN clusters. Based on nuclear data, maximum divergence within the group is 2.2% (based on ten specimens and TPI) and the nearest neighbour is 1.5% ( P. pseudocoactula , both genes combined) or 1.0% different ( P. wesmaeli , only NaK). Host plants. Perhaps Betula sp. ( Verzhutskii 1981 ), if the species was correctly identified. Distribution and material examined. West Palaearctic, Nearctic. Specimens studied are from Finland.
