Nematus albitibiaCosta, 1859: 21. Syntype(s) ♂ possibly in MZUN, not examined. Type locality: Sila Grande, Calabria, Italy. Nematus puncticepsThomson, 1863: 619. Syntypes ♀♂ in MZLU, examined. Type locality: Dalarne, Stockholm, Ostergoethland, Smaland, and Skane, Sweden. Nematus agilisZaddach in Brischke, 1884: 142. Primary homonym of Nematus agilisCresson, 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). Pristiphora aterrimaLindqvist, 1977: 92, syn. n.Holotype ♀ (DEI-GISHym20896) in MZH, examined. Type locality: Tolyany, Usolje, Irkutsk, Russia.
Similar species. Externally, the most similar species are P. armata, P. confusa, P. leucopus, P. opaca, and P. subopaca, from which it is best distinguished by the structure of the saw (Figs 41-42) and the penis valve (Fig. 78). On the inner surface of the lancet there are small spiny pectines (or dentes semicirculares) that reach the sclerora, which are absent in other similar species. The saw (Fig. 42) and external morphology of the holotype of Pristiphora aterrimaLindqvist, 1977 is not distinguishable from the studied P. albitibiaspecimens and therefore we synonymise Pristiphora aterrimawith Pristiphora albitibia.
Genetic data. Based on COI barcode sequences, P. albitibiabelongs to its own BIN cluster (BOLD:ACH1762) (Fig. 1). The nearest neighbour (BOLD:AAL8277, P. astragali?) is 2.06% different. Although there are no nuclear TPI sequences for any of the genetically closest (according to COI barcodes) species ( P. astragaliand P. sootryeni), the three sequenced specimens of P. albitibiaare nearly identical to each other (one specimen differed by one nucleotide from the other two) and clearly different from the other sequenced species (Fig. 2).
Host plants. Vicia craccaL. ( Stein 1885, as P. puncticeps; Vikberg 2006), V. hirsuta(L.) Gray, V. tetrasperma(L.) Schreb. ( Kangas 1985, as P. puncticeps), Vicia baicalensisTurcz., Vicia unijugaA. Br. ( Verzhutskii 1981, as P. puncticeps).
Distribution and material examined. Palaearctic. Specimens studied are from Estonia, Finland, Germany, Russia, and Sweden.
