Tenthredo Pini [sic!] Retzius, 1783: 73, by indication to Degeer (1771: 1001-1002, Pl. 38. figs 5-7). Primary homonym of Tenthredo pini Linné, 1758 [= Diprion pini ( Linné, 1758)]. Syntype(s) possibly in NHRS. Type locality: possibly Lövstabruk, Uppland, Sweden (place of residence of Degeer; see Taeger and Blank 1998).

Tenthredo abietina Christ, 1791: 447, by indication to Degeer (1771: 1001-1002, Pl. 38. figs 5-7). Syntype(s) possibly in NHRS. Type locality: possibly Lövstabruk, Uppland, Sweden (place of residence of Degeer; see Taeger and Blank 1998).

Tenthredo abietum Hartig in Hartig and Hartig, 1834: 984-985. Lectotype ♀ (GBIF-GISHym3183; here designated) in ZSM, examined. Type locality: not stated.

Nematus (Nematus) limbatus Dahlbom, 1835b: 9. Not available. Nomen nudum. Note. Not available through an indication, only internal reference on " Nematus abietinus No. 86", without giving any differences.

Nematus (Nematus) abietinus Dahlbom, 1835b: 9. Note. Description by indication on "Mouche à scie du Sapin De Geer". Syntype(s) possibly in NHRS. Type locality: possibly Lövstabruk, Uppland, Sweden (place of residence of Degeer; see Taeger and Blank 1998).

Nematus truncatus Hartig, 1837: 207. Holotype ♀ possibly lost. Type locality: Harz, Germany. Synonymised with Lygaeonematus pini by Konow (1904b).

Similar species.

The most similar species is P. compressa , which is on average larger (6.0-9.0 vs. 4.0-6.5 mm) and has hypopygium posteriorly excised (not excised in P. abietina ) (Figs 62-63). Males are best recognised by examining penis valves (Fig. 283). See the Key for more details.

Genetic data.

Based on COI barcode sequences, P. abietina belongs to the same BIN cluster (BOLD:AAK9450) as P. compressa , P. decipiens , P. gerula , P. pseudodecipiens , P. saxesenii , and possibly P. robusta . Maximum distance within the BIN is 2.18% and minimum between species distance is 0.00%. The nearest neighbour to BOLD:AAK9450, diverging by minimum of 3.92%, is BOLD:ACO1401 ( P. euxantha Huflejt, 2006, a species not treated here). Based on nuclear data, within species divergence is 0.1% (based on two specimens and NaK) and the nearest neighbour is 1.2% different ( P. saxesenii , both genes combined).

Host plants.
