Nanofrustulum shiloi (J.J.Lee, Reimer & McEnery) Round, Hallsteinsen & Paasche

This species was reported from Guam by Lobban & Navarro (2009) (figs. 40–43) but based on recent work by C.Li et al. (2018), the specimens illustrated are not this species or genus and cannot be identified to any of the other genera described there. These specimens must await further study. We do not have any other specimens so far that can be identified as N. shiloi, although we anticipate it is present in the flora. The images remain posted in ProtistCentral under the name GU7B-UnID (http://www.protistcentral.org/Taxa/get/taxa_id/586261).
