Genetic data.

Based on COI barcode sequences, specimens of the rufipes group are divided between five BIN clusters (BOLD:AAI2590, BOLD:AAU8834, BOLD:ABU9175, BOLD:ABV4437, and BOLD:ACW1774), four of which are found in Europe (BOLD:AAU8834 is so far known only from Canada) (Fig. 5). Minimal distances between these clusters are 3.06-4.35%. 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 1.4% (based on eight specimens and TPI) and the nearest neighbour is 1.0% ( P. cincta , both genes combined) or 0.4% different ( P. cincta , only NaK).

Host plants.

Thalictrum aquilegiifolium L. ( Pschorn-Walcher and Altenhofer 2006, Macek 2016), T. minus L. ( Takeuchi 1949, Okutani 1967).

Distribution and material examined.

Palaearctic. Specimens studied are from Austria, Germany, and United Kingdom.
