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 trochanterica (Lindqvist, 1952) Fig. 213 Lygaeonematus (Lygaeotus) trochantericus Lindqvist, 1952: 101-102. Holotype ♀ (DEI-GISHym31566) in MZH, examined. Type locality: Utsjoki, Outakoski, 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. Unknown. Distribution and material examined. West Palaearctic. Specimens studied are from Finland.
