Pristiphora albitibia (Costa, 1859)  Figs 6, 20, 44, 188, 273

Nematus albitibia  Costa, 1859: 21. Syntype(s) ♂ possibly in MZUN, not examined. Type locality: Sila Grande, Calabria, Italy.

Nematus puncticeps  Thomson, 1863: 619. Syntypes ♀♂ in MZLU, examined. Type locality: Dalarne, Stockholm, Ostergöthland, Småland, and Skåne, Sweden. Synonymised with P. albitibia  by Costa (1894).

Nematus agilis  Zaddach in Brischke, 1884: 142. Primary homonym of Nematus agilis  Cresson, 1880 [= Euura agilis  (Cresson, 1880)]. 3 ♂♀ syntypes possibly destroyed ( Blank and Taeger 1998). Type locality: not specified, but probably in former East Prussia (now Kaliningrad Oblast of Russia, or Poland). Synonymised with P. staudingeri  auct. by Konow (1905).

Pristiphora aterrima  Lindqvist, 1977: 92. Holotype ♀ (DEI-GISHym20896) in MZH, examined. Type locality: Tolyany, Usolje, Irkutsk, Russia.

Pristiphora nigropuncticeps  Haris, 2002: 75-76, syn. n. Holotype ♂ (DEI-GISHym80345; in HNHM, examined. Type locality: Nukht, Bogd Khan Mountain, Ulaanbaatar, Mongolia.

Similar species.

Externally, the most similar species are P. armata  , P. confusa  , P. leucopus  , P. opaca  , P. sootryeni  , and P. subopaca  , from which it is best distinguished by the structure of the lancet (Fig. 188), the penis valve (Fig. 273), and the colour of pterostigma (Fig. 40) (see the Key).

Genetic data.

Based on COI barcode sequences, specimens of this species are divided between two BIN clusters (BOLD:ACH1762 and BOLD:ADH0371) (Fig. 4). Minimum distance between the clusters is 4.6%. Based on nuclear data (four specimens and both genes combined), maximum within species divergence is 0.3% and the nearest neighbour is 0.8% different ( P. astragali  or P. caraganae  ). Two studied specimens (male and female) from Finland with a highly divergent barcode (BOLD:ADH0371; DEI-GISHym80018 and DEI-GISHym80357) are morphologically indistinguishable from other P. albitibia  specimens and this is congruent with nuclear data (both genes) from the female DEI-GISHym80357 (divergence from the other three specimens is 0.1-0.3%).

Host plants.

Vicia cracca  L. ( Stein 1885, as P. puncticeps  ; Vikberg 2006), V. hirsuta  (L.) Gray, V. tetrasperma  (L.) Schreb. ( Kangas 1985, as P. puncticeps  ), V. baicalensis  Turcz., V. unijuga  A. Br. ( Verzhutskii 1981, as P. puncticeps  ).

Rearing notes.

See Vikberg (2006).

Distribution and material examined.

Palaearctic. Specimens studied are from Estonia, Finland, Germany, Mongolia, Russia (Irkutsk Oblast), and Sweden.
