Later, three additional congeners were described from the Nearctic: M. macnamarai (Folsom, 1918), M. capitona Maynard, 1951, and M. spiniseta Maynard, 1951. Following opinions by Folsom (1937) and Christiansen & Bellinger (1980), these are all treated as synonyms of the widespread M. grandiceps on www. collembola.org. However, M. grandiceps was shown to be a complex of several distinct Nearctic and Eastern Palaearctic forms (Fjellberg 1999). Palaearctic species of the genus were recently revised and M. macnamarai was redescribed based on the types and fresh material (Potapov et al. 2018). In the same paper the authors also noted that “the Nearctic fauna is probably more diverse and consists of at least six species, mostly undescribed” (p. 71). That is why at least some of the above records, especially those outside the Arctic, need verification. General distribution: modern reliable records of the species are restricted to the Northwestern Nearctic (Alaska) and Eastern Palaearctic (see Potapov et al. 2018). : Published as part of Babenko, Anatoly, Stebaeva, Sophya & Turnbull, Matthew S., 2019, An updated checklist of Canadian and Alaskan Collembola, pp. 1-125 in Zootaxa 4592 (1) on pages 73-74, DOI: 10.11646/zootaxa.4592.1.1, http://zenodo.org/record/2656929 : {"references": ["Reuter, O.
