When published, the illegitimate name included in synonymy all elements of the previously validly published two fossil-species: Anthrophyopsis nilssonii Nath. (in Sveriges Geol. Undersök., C, Avhandl. 27: 43. 1878) and Anthrophyopsis crassinervis Nath. (in Sveriges Geol. Undersök., C, Avhandl. 27: 44. 1878), although the latter fossil-species was listed with a query.
