It was listed as occurring in Greenland by Henriksen (1939), with the only data “ W. G.: [69 ° 15 '] ”. [W. G. standing for West Greenland]. Henriksen and Lundbeck (1917) gave additional information on the single putative record of Cladius grandis from Greenland, under the name Trichiocampus viminalis (Fallén, 1808) [translated from Danish]:</p><p>“ West Greenland: Of this new species for the Greenlandic fauna a female has been taken at Godhavn on Disko (Zool. Mus.). Not known from East Greenland. Geogr. Distribution: Northern and Central Europe. The larva lives on poplar, but may also occur on willow; this last is certainly the case in Greenland. ”</p><p>The specimen is no longer to be found in NHMD, where it was originally housed. We agree with Vilhelmsen’s decision to exclude the species from the list of Greenland insects. Henriksen and Lundbeck (1917) were wrong in stating that C. grandis uses Salix as a host: its larva feeds only on Populus spp. There is no evidence for the use of Salix as a host, and occasional such statements in the literature probably arose through misidentifications of the very similar larvae of C. aeneus Zaddach, 1859 . There is no native Populus species in Greenland, although some species have been planted, for example, at Narsarsuaq (but probably after ca. 1941). If the claimed Greenlandic C. grandis specimen was correctly identified, then the record must relate to the chance introduction of a single individual to an area where it could not become established.</p></div>	https://treatment.plazi.org/id/EAD3D95454915A1A994629BD6B189474	Public Domain	No known copyright restrictions apply.

Two specimens from Nuuk (DEI-GISHym 40557, DEI-GISHym 40558) are smaller (Fig. 5), have a somewhat smaller subapical tooth of the claw than most other specimens, and the mesonotum and mesepisternum are shinier.</p><p>Habitats.</p><p>Favours moist areas, such as snow-patch edges and the banks of streams, and is absent or very scarce in drier places, even when the larval host plant is present.</p><p>Host plants and biology.</p><p>The only known host is Bistorta vivipara (L.)

Kuusamo Region in Finland and Västerbotten Province in Sweden). The host plant is widespread and abundant in Iceland, but E. excisa has not so far been recorded there.</p><p>Genetics.</p><p>The COI sequencing of four specimens yielded five different variants (Fig. 7). The dominant variants of the two atypical specimens from Nuuk (DEI-GISHym 40557, 40558) are identical to a specimen from Sweden (SL 69 _ G 1) and 0.4 % different from the typical specimens from Kapisillit and Narsarsuaq. A larva from Kapisillit (TUZ 399073) has a unique sequence that is almost identical (0.2 % different) to a female from Narsarsuaq (TUZ 399053). Curiously, the dominant variant of the Narsarsuaq (TUZ 399053) specimen is identical (1078 bp of COI) to Euura declinata from Estonia (Fig. 7). Two of the specimens (DEI-GISHym 40558, TUZ 399053) also yielded additional variants of COI (one each) that are very similar to the other E. excisa sequences (0.2–0.4 % different).</p><p>Comparing nuclear genes (Fig. 8), the atypical specimens from Nuuk (DEI-GISHym 40557, DEI-GISHym 40558) are identical and 0.00–0.08 % different from three Fennoscandian E. excisa (Finland and Sweden, with at least 3425 bp available). The sequenced specimens from Kapisillit and Narsarsuaq (TUZ 399073, TUZ 399053) are identical and 0.11–0.43 % different from all the other specimens (Nuuk and Fennoscandia). The atypical specimens from Nuuk are much more heterozygous (possess distinct haplotypes for five nuclear genes out of seven) compared to the specimens from Kapisillit (two nuclear genes out of seven with two haplotypes) and Narsarsuaq (all five sequenced nuclear genes homozygous). The haplotypes of the Nuuk specimens are very similar to the haplotypes of Fennoscandian specimens, hence the higher similarity between them in distance calculations compared to the specimens from Kapisillit and Narsarsuaq.</p></div>	https://treatment.plazi.org/id/E3FB4E8A1FF85742959593D88F24E58B	Public Domain	No known copyright restrictions apply.

(2025), who considered it to be possibly conspecific with E. obscuripes . A closer examination of the single barcoded specimen from Greenland (grhym- 00071 in BOLD; Fig. 11) revealed that it matches well with the holotype of A. groenlandicus (the barcoded specimen is somewhat darker). Both were collected on the Wollaston Forland Peninsula (North-East Greenland). The barcoded specimen belongs to the cluster BOLD: AAQ 0427, which contains at least Euura obscuripes (specimen DEI-GISHym 31073; see Prous et al. 2025: 180), but possibly also some other species of the Euura toeniata species group. The colouration of the A. groenlandicus holotype and specimen grhym- 00071 is similar to paler females from Europe (formerly known as Amauronematus poppii Konow, 1904), but the barcode sequence of grhym- 00071 is closest to a specimen from California (DEI-GISHym 31073), which in its darker colouration and nuclear genes is a more typical form of E. obscuripes (see Prous et al. 2025). Nematus borealis Marlatt is here synonymised with E. obscuripes (external morphology is consistent with this), but this requires confirmation by studying genitalia and genetics. The genitalia of the Nematus borealis holotype have been extracted but are unfortunately now lost (the associated microvial is empty, J. Weintraub, personal communication).</p><p>Genetics.</p><p>A barcoded specimen from Northeast Greenland (Zackenberg Research Station; grhym- 00071 in BOLD) is closest to unidentified Euura toeniata group specimens from northern Canada (0.3 % different).</p></div>	https://treatment.plazi.org/id/F8C48DAD58275A0CB0D93A9B8008926D	Public Domain	No known copyright restrictions apply.

The saw of E. excisa is similar, but serrulae are somewhat more protruding and the gaps between serrulae larger than in E. punctifrons (Fig. 12). Benson (1962) mentioned Pachynematus parvilabris (Thomson, 1863) from Greenland (Nugssuaq, 70.69, – 54.57), which was not found in NHMD but is probably the same species as zmuc 00023366.</p></div>	https://treatment.plazi.org/id/A74CA52E8FBA5DD283765AFBD9645EEA	Public Domain	No known copyright restrictions apply.

Subdivision of Greenland into zoogeographic regions after Böcher et al. (2015: p. 22, fig. 1 [map]).</p><p>Habitat.</p><p>Specimens were found throughout the area designated as the Arboretum Groenlandicum, an area covering about 150 ha to the east and north of Narsarsuaq settlement.</p><p>Host plants and biology.</p><p>Larvae feed on several Larix species (Prous et al. 2017). Established in the Greenlandic Arboretum are at least Larix decidua Mill., L. sibirica Ledeb., L. laricina (Du Roi) K. Koch, and L. gmelinii (Rupr.) Göpp., of which L. sibirica was the first non-native tree species planted there, in 1966, and is now the most numerous larch species (Meilby et al. not dated). In Europe, P. laricis is regularly bivoltine but can be univoltine at high altitudes in the Alps (Pschorn-Walcher and Altenhofer 2000).</p><p>Distribution.</p><p>Previously only known from the Palaearctic, where it occurs practically throughout the natural range of Larix, from the mountains of central Europe eastwards through northern Russia and into Korea, northern China, and Japan (Sundukov 2017). It is also widespread nearly everywhere where larches have been planted in Europe outside their natural ranges.</p><p>Remarks.</p><p>Pristiphora laricis was very abundant at Narsarsuaq, and many individuals were swept from plants other than Larix . It would have been possible, with little effort, to collect a much larger number of specimens. One female (TUZ 109658) was collected by sweeping the ground with Salix herbacea, about 2 km from the nearest Larix tree. The first Greenlandic specimens of P. laricis were collected at Narsarsuaq in late July 2018 by S. Harding. The occurrence of the species in Greenland was already indicated by Taeger et al. (2018).</p><p>Genetics.</p><p>The COI of two sequenced specimens (TUZ 399047, TUZ 399048) is identical to a few specimens from Finland and Germany. Based on nuclear genes, the Greenlandic specimens are 0.2 % different from each other and are closest to a specimen from Finland (minimum distance 0.04 %). The other specimens with available nuclear data (two from Estonia, one from Norway) are 0.4–0.5 % different from the Greenlandic specimens.</p></div>	https://treatment.plazi.org/id/CF47729A62B05BAFBA69351555116F4D	Public Domain	No known copyright restrictions apply.
