The morphological ontogeny of Limnozetes solhoyorum sp. nov. from Norway is described and illustrated. This species is most similar to L. guyi Behan-Pelletier, 1989 as adult, but differs from it mainly by the sculpture of notogaster, shorter prodorsal seta in and notogastral setae, especially p1, and the distribution of posterior notogastral setae. The tritonymph of L. solhoyorum differs from that of L. guyi by shorter gastronotal setae c3, dm, dp, lm and lp. In the deutonymph, tritonymph and adult of both species, setae d and l' from genu IV are absent.
