Distribution

Arctic and Pacific Ocean drainage.

Notes

This taxon is morphologically identical to L. sp. N and L. sp. S of Yamazaki et al. (2006). These two putative species of Lethenteron are recognized only by a molecular analysis ( Yamazaki et al. 2006), so we treated them as one species complex here because of the difficulty in differentiating the species on morphological characters alone (see Nakabo and Kai 2013 and its citations). Adults were observed in lotic environments, while larvae were observed in lentic environments such as in the silty/sandy bottom of floodplains.
