Notes for Notoplana similis
Listed in Prudhoe (1985) (citation) as "'similis Stimps.' Dawydoff, 1952, 81" (i.e., in quotation marks, and as if Dawydoff thought the species was described by Stimpson). Does not exist according to Faubel 1983 (citation). Dawydoff possibly meant to refer to N. humilis Stimpson, 1857.
