Pristiphora leucopus ( Hellen, 1948)  Figs 192, 265

Nematus vitreipennis  Eversmann in Kawall, 1864: 295. Nomen oblitum ( Prous et al. 2016). Lectotype ♀ (DEI-GISHym30027; designated by Prous et al. 2016) in ZIN, examined. Type locality: In promontor. Uralensibus [foothills of Ural mountains], Russia.

Nematus (Pristiphora) ruficornis var. leucopus  Hellén, 1948b: 116. Nomen protectum ( Prous et al. 2016). No syntypes were found in MZH. Type locality: Joutseno, South-Eastern Finland, Finland and Pionerskoye [ Kuolemajärvi], Leningrad Oblast, Russia.

Similar species.

The most similar species is P. armata  . Differences between these two species, which unfortunately are not very strong, were discussed by Grearson and Liston (2012) and Prous et al. (2016).

Genetic data.

Based on COI barcode sequences, P. leucopus  belongs to the same BIN cluster (BOLD:AAQ2302) as P. armata  (Fig. 4). Maximum distance within the BIN is 2.41% and minimum between species distance is possibly 0.00%. The nearest neighbour to BOLD:AAQ2302, diverging by minimum of 2.76%, is BOLD:AAG3568 ( P. aphantoneura  , P. bifida  , P. confusa  , P. luteipes  , P. opaca  , P. pusilla  , P. staudingeri  , and P. subopaca  ). Neither does nuclear sequence data allow separation of P. leucopus  from P. armata  . Based on nuclear data, maximum within species divergence is 0.4% (based on three specimens and TPI or NaK) and the nearest neighbour is 0.0% different ( P. armata  , based on TPI including introns).

Host plants.

Tilia cordata  Mill. ( Kangas 1985, Grearson 2006, Grearson and Liston 2012), Tilia x vulgaris  Hayne ( Grearson 2006).

Distribution and material examined.

West Palaearctic. Specimens studied are from Austria, Finland, Germany, United Kingdom, Russia (Ural mountains), and Sweden.
