Pristiphora coactula (Ruthe, 1859)  Fig. 217

Nematus coactulus  Ruthe, 1859: 307-308. Holotype ♀ in NMW, not examined. Type locality: Iceland.

Nematus winnipeg  Norton, 1867b: 198. Lectotype ♀ in ANSP (designated by Cresson 1928, spelt as “winnepeg”), not examined. Type locality: Lake Winnipeg, Manitoba, Canada. Synonymised with P. coactula  by Benson (1962).

Nematus alpinus  Thomson, 1871: 98. Lectotype ♀ (MZLU2014449; here designated) in MZLU, examined. Type locality: Skalstugan, Jämtland, Sweden.

Nematus winnipegensis  W.F. Kirby, 1882: 143. Replacement name for Nematus winnipeg  Norton, 1867.

Lygaeonematus pachyvalvis  Konow, 1904a: 197 (key). Syntype ♀ (GBIF-GISHym3913) in SDEI, examined. Type locality: Mt Dore, France; Kanin Peninsula, Nenets Autonomous Okrug, Russia; and Vassijaure, Torne Lappmark, Sweden.

Pristiphora dawsoni  Rohwer, 1908: 109. Holotype ♀ in NSM ( Smith 1983), not examined. Type locality: Ute Creek, Costilla, Colorado, USA. Synonymised with P. coactula  by Smith (1979).

Similar species.

Species limits in the carinata  group are still unclear.

Genetic data.

Based on COI barcode sequences, specimens of the carinata  group are divided between four BIN clusters (BOLD:AAF4995, BOLD:ABU8603, BOLD:ACL1744, BOLD:ACL1745), which form a monophyletic group (Fig. 5). Minimal distances between these clusters are 1.2%-4.48%. Because of unresolved taxonomy, it is not yet clear how different species are divided among these BIN clusters. Based on nuclear data, maximum divergence within the group is 2.2% (based on ten specimens and TPI) and the nearest neighbour is 1.5% ( P. pseudocoactula  , both genes combined) or 1.0% different ( P. wesmaeli  , only NaK).

Host plants.

Vaccinium uliginosum  L (ex ovo rearing experiments by VV).

Rearing notes.

Ovipositing experiment no. 46/1969: Finland, North Karelia, Kontiolahti, Venejoki. On 14-15.VI.1969 one captured female laid several eggs in pockets near leaf-margin on underside of the young leaves of Vaccinium uliginosum  . Larvae hatched on 20.VI.1969, 6 larval instars were observed. Larvae fed on the margins of leaves at night. During the day they hid near the bottom of the rearing container. The final feeding instar lasted some 30 days. No “extra” moult after feeding, prepupae were seen on 7.VIII.1969.

Distribution and material examined.

West Palaearctic, Nearctic. Specimens studied are from Finland, France, and Sweden.
