Pristiphora friesei (Konow, 1904)


Pristiphora friesei (Konow, 1904)  Figs 33, 79-81, 174-176, 277

Lygaeonematus  Friesei [sic!] Konow, 1904a: 195, 208. Lectotype ♀ (GBIF-GISHym3914; here designated) in SDEI, examined. Type locality: Airolo, Ticino, Switzerland (not in Tirol, Austria, as written by Konow 1904a, b; see also Enslin, 1916: 509). Note. Enslin (1916: 509) and Muche (1974: 136-137) referred to the single female specimen in the SDEI as the type of P. friesei  (under the name P. frisei  [sic!] by Muche 1974). Neither reference constitutes a valid lectotype designation according to ICZN Article 74.5, because the specimen was not unambiguously selected from the syntype series. However, because Enslin and Muche based their concept of the species on the specimen in the SDEI, we hereby designate this specimen as the lectotype.

Pristiphora atrata  Lindqvist, 1975: 13, syn. n. Holotype ♀ (DEI-GISHym20834) in MZH, examined. Type locality: Goloustnoje, Irkutsk, Russia. Note. The holotype was reared by B. N. Verzhutskii from a larva found on Vaccinium uliginosum  L. on May 29, 1966 (label data; see also Verzhutskii 1981), which we interpret as an accidental find, as the host plant of P. friesei  is Larix  ( Schedl 1976, Liston et al. 2006). Lancet and external morphology of atrata  does not differ from friesei  .

Similar species.

The most similar species is P. laricis  , which tends to be paler, but darker specimens could be mistaken for P. friesei  . There are small differences in the structure of the lancets: the tangium appears to be without campaniform sensilla and there are fewer setae in P. friesei  , while campaniform sensilla are present and there are more setae in P. laricis  (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 longer in P. friesei  (see the Key).

Genetic data.

Based on COI barcode sequences, P. friesei  forms its own BIN cluster (BOLD:ABV3411). When specimens that have 1 bp deletion in the barcoding region (e.g. DEI-GISHym11558) are included (excluded from calculations in BOLD), maximum distance within P. friesei  is 3.5% and the nearest P. laricis  specimens are only 2.3% different (based on full barcodes), but P. friesei  nevertheless forms a monophyletic group (Fig. 3). The nearest neighbour to BOLD:ABV3411 (excluding the specimens with 1 bp deletion), diverging by minimum of 4.67%, is BOLD:AAQ3707 ( P. laricis  ). No nuclear data are available.

Host plants.

Larix decidua  Mill. ( Schedl 1976), Larix x eurolepis  ( Liston et al. 2006).

Distribution and material examined.

Palaearctic. Specimens studied are from Germany, Italy, Russia (Irkutsk Oblast), Switzerland, and United Kingdom.
