Pristiphora amphibola ( Foerster, 1854)  Figs 165, 293

Nematus amphibolus  Förster, 1854b: 329-330. Lectotype ♀ (GBIF-GISHym3195) in ZSM, examined. Type locality: Aachen, North Rhine-Westphalia, Germany.

Nematus laetus  Cameron, 1883: 194-195. Syntype(s) ♀ possibly in BMNH, not examined. Type locality: Mickleham, Surrey, United Kingdom. Synonymised as fraternus  with P. amphibola  by Benson (1948).

Nematus fraternus  Cameron, 1885: 73-74. Replacement name for Nematus laetus  Cameron, 1883.

Similar species.

The most similar species are P. nigella  and P. parva  , from which females of P. amphibola  can be distinguished by the combination of dark coloration (almost completely black) and long valvula 3 (see the Key, and Beneš et al. 1981). Males are best recognised by examining penis valves (see the Key).

Genetic data.

Based on COI barcode sequences, P. amphibola  belongs to the same BIN cluster (BOLD:AAF5120) as P. nigella  (Fig. 5). Maximum distance within the BIN is 0.71% and minimum between species distance is possibly 0.00%. The nearest neighbour to BOLD:AAF5120, diverging by minimum of 2.26%, is BOLD:ABV9415 ( P. parva  ). Based on nuclear data (one specimen; NaK), the nearest neighbour is 0.4% different ( P. nigella  ).

Host plants.

Picea abies  (L.) Karsten ( Crooke 1957, Beneš et al. 1981), Picea sitchensis  (Bong.) Carriere (Crooke, 1957).

Distribution and material examined.

West Palaearctic. Specimens studied are from Finland and Germany.
