Pristiphora laricis (Hartig, 1837)  Figs 64, 177-178, 279-280

Nematus laricis  Hartig, 1837: 203-204. Lectotype ♀ (GBIF-GISHym3328; here designated) in ZSM, examined. Type locality: Germany according to the title of the publication.

Nematus ruficollis  Hartig, 1840: 27. Lectotype ♀ (GBIF-GISHym3405; here designated) in ZSM, examined. Type locality: not stated.

Nematus leucocnemis  Förster, 1854b: 433-434. Lectotype ♀ (GBIF-GISHym3333; designated by Liston 1995) in ZSM, examined. Type locality: Aachen, North Rhine-Westphalia, Germany.

Nematus oblongus  Cameron, 1882: 539. Syntype(s) possibly in BMNH, not examined. Type locality: England, United Kingdom. Synonymised with Lygaeonematus laricis  by Konow (1904a).

Nematus laricivorus  Brischke, 1883a: pl. I, 1e. Described from larvae, types possibly destroyed ( Blank and Taeger 1998). Type locality: not stated, but probably in former East Prussia (now Kaliningrad Oblast of Russia, or Poland). Synonymised with Pristiphora laricis  by Konow (1898).

Nematus rusticanus  Brischke, 1884: 128-129. Holotype ♀ possibly destroyed ( Blank and Taeger 1998). Type locality: not stated, but probably in former East Prussia (now Kaliningrad Oblast of Russia, or Poland). Synonymised with Lygaeonematus laricis  by Konow (1904a).

Pachynematus ravidus  Konow, 1903: 382 (key). Lectotype ♀ (GBIF-GISHym3855; designated by Taeger and Blank 1998) in SDEI, examined. Type locality: Zermatt, Valais, Switzerland. Synonymised with Pristiphora laricis  by Koch (1989).

Lygaeonematus paedidus  Konow, 1904a: 195, 205. Lectotype ♀ (GBIF-GISHym3854; designated by Koch 1989 as “holotype”) in SDEI, examined. Type locality: Ulm ( Baden-Württemberg) or Erfurt (Thuringia), Germany (the specimen has two different labels, with locality names that do not match). Synonymised with Pristiphora laricis  by Koch (1989).

Pachynematus nigricorpus  Takagi, 1931: 32-33 (Jap.), 11-12(Engl.), syn. n. Syntypes possibly in the National Institute of Forest Science (previously Forestry Experiment Station), Seoul, South Korea, not examined. Type locality: North Korea.

Similar species.

The most similar species is P. friesei  , which tends to be darker (see the Key). There are small differences in the structure of the lancets: campaniform sensilla are present on the tangium and there are more setae in P. laricis  , while campaniform sensilla appear to be absent and there are fewer setae in P. friesei  (Figs 174-178). There appear to be no consistent differences in penis valves (Figs 277, 279-280), contrary to Chevin (1974), but the antennae are shorter in P. laricis  (see the Key). One studied female from Scotland (DEI-GISHym31503) had a red band on the abdomen, like P. cincta  and P. erichsonii  , but all these species can be distinguished based on the shape of valvula 3 and the structure of the lancet (Figs 104-105, 145-146 for P. cincta  ; Figs 124-125, 170 for P. erichsonii  ; Figs 79-81, 177-178 for P. laricis  ). As already suspected by Vikberg (1975), we treat nigricorpus  Takagi as synonym of laricis  Hartig. The description by Takagi (1931) fits well with P. laricis  (pale labrum, length of antenna in male 3-4 mm) rather than P. friesei  (black or dark brown labrum and length of antenna in male about 5 mm). Haris (2006b) apparently misinterpreted P. laricis  , because the figure of valvula 3 given for this species (Fig. 10 in Haris 2006b) belongs to the leucopodia  group, tenuiserra  or some other species where valvula 3 can extend or extends beyond cerci. However, the figure of valvula 3 (Fig. 30 in Haris 2006b) given for nigricorpus  Takagi by Haris (2006b, as P. nigrocarpa  ) does fit with P. laricis  (Fig. 79).

Genetic data.

Based on COI barcode sequences, P. laricis  forms its own BIN cluster (BOLD:AAQ3707). Maximum distance within the BIN is 2.09% (Fig. 3). The nearest neighbour to BOLD:AAQ3707, diverging by minimum of 4.31%, is BOLD:ABV3411 ( P. friesei  ). Based on nuclear data (three specimens and TPI or NaK), within species divergence is 0.2% (NaK) or 1.2% (TPI) and the nearest neighbour is 2.3% different ( P. nigriceps  , only NaK).

Host plants.

( Kangas 1985, Huflejt and Sawoniewicz 1999), L. gmelinii  (Rupr.) Kuzen., L. laricina  (Du Roi) K. Koch, L. occidentalis  Nutt., Larix x eurolepis  A. Henry ( Huflejt and Sawoniewicz 1999).
