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).
