Taxonomic remark Within this subspecies Focke (1836) unites Fasciola quadrangularis (keeping the name) and Planaria tetragona. Graff (1882) brings all under Mesostoma tetragonum, while Luther (1963) and Noreña Jannsen & Faubel synonymise the subspecies with M. craci. Noreña-Jannsen & Faubel, als of mention that part of the Focke's (1836) P. ehrenbergii actually refers to M. tetragonum, hence the subspecies probably was split into two other species M. tetragonum and M. craci.
