03A787AEFFF0AE02512601D8C79DFC55.taxon	materials_examined	Type genus: Lepechinella Stebbing, 1908, by original designation.	en	Lörz, Anne-Nina, Brix, Saskia, Jażdżewska, Anna M., Hughes, Lauren Elizabeth (2020): Diversity and distribution of North Atlantic Lepechinellidae (Amphipoda: Crustacea). Zoological Journal of the Linnean Society 190: 1095-1122, DOI: 10.1093/zoolinnean/zlaa024, URL: https://academic.oup.com/zoolinnean/advance-article/doi/10.1093/zoolinnean/zlaa024/5825067
03A787AEFFFEAE0E52B405A1C695F91B.taxon	materials_examined	Type locality: North Atlantic, North Sea (between Orkney Islands and Shetland Islands), 59 ° 041 ’ N, 3 ° 08 ’ W, 850 m. Remarks: Lepechinella chrysotheras is not encountered in the samples from IceAGE expeditions. This species is only known from the holotype of Stebbing (1908) and three additional male specimens listed by Stephensen (1944). There are currently no reported female specimens of L. chysotheras. Stebbing (1908) does not list the institution where the type material is deposited and, unfortunately, no type material for L. chrysotheras was located at the NHM, London, which was the main repository of Stebbing’s personal collection. Stebbing (1908) cited material as collected in the ‘ North Sea’, by the RV Goldseeker, but this is a historic use of the name North Sea, as in more recent times, the term ‘ North Sea’ is restricted to the region between the United Kingdom and the European mainland. Most importantly, the type locality listed in the formal taxonomic description of the species is given only as latitude and longitude coordinates. Following these coordinates, the collection locality is positioned between the Orkney Islands and the Outer Hebrides, hence outside the modern definition of the North Sea (a technical, but critical point in assessing regional listings and geographic species ranges). Depth range: 850 to 900 m. Distribution: North Atlantic, between Orkney Islands and Shetland Islands (Stebbing, 1908), South of the Faeroes (Stephensen, 1944) (Fig. 9 B; Tables 1, 2).	en	Lörz, Anne-Nina, Brix, Saskia, Jażdżewska, Anna M., Hughes, Lauren Elizabeth (2020): Diversity and distribution of North Atlantic Lepechinellidae (Amphipoda: Crustacea).

03A787AEFFFCAE0952A505E1C66BF952.taxon	materials_examined	Type locality: 78 ° 02 ’ N, 09 ° 12 ’ E (West of Svalbard), depth unknown; station sampled by the Icebreaker Sadko. Remarks: Lepechinella eupraxiella Barnard, 1973 was not encountered in samples from the IceAGE expeditions. It appears that the validation of Lepechinella eupraxiella is problematic. Known only from the original illustration by Gurjanova (1951) under the name L. arctica, Barnard’s (1973) subsequently described the species based on literature assessment. Barnard nominated the specimen illustrated in Gurjanova’s figure 465 as the type material, which provides only a partial illustration of the specimen. The species is known only from a single individual collected by Icebreaker Sadko in Polar Basin (‘ Полярный бассейн’). Given the statement of Gurjanova (1951, p. 675 and p. 678) that it fully agreed with the description and figure by Schellenberg (1925) of L. arctica, the sympatric distribution of both species as well as the erection of the species only on the basis of single figure one cannot exclude that L. eupraxiella is a junior synonym of L. arctica. The study of the holotype of L. eupraxiella may help solving this taxonomic problem. Depth range: Unknown. Distribution: West of Svalbard (Gurjanova, 1951; Barnard, 1973) (Fig. 7 A; Tables 1, 2).	en	Lörz, Anne-Nina, Brix, Saskia, Jażdżewska, Anna M., Hughes, Lauren Elizabeth (2020): Diversity and distribution of North Atlantic Lepechinellidae (Amphipoda: Crustacea).

Remarks: Material reported here are larger specimens, 7.2 mm, (Figs 4, 5, 13), than the holotype ZMBN 99134, 5.5 mm. The IceAGE material includes additional juvenile and female specimens from sites close to the type locality ‘ south of Iceland’ and at a similar 2000 – m depth range. The rostrum shape, lateral cephalic lobe and head anteroventral lobe show some variation between juveniles, with more slender projections, and adults, which have broader and more sinusoidal projections (Fig. 4). The present study extends the known distribution of L. victoriae north to the Denmark Strait and east to the Faeroe Islands Ridge. The collection data also broadens the bathymetric range from the middle bathyal (2355 m) to the shallower upper bathyal (at 679 m deep). Depth range: 679 to 2750 m.
