AB Planothidium engelbrechtii (CHOLNOKY) ROUND et BUKHT. was originally described in 1955 from South Africa as Achnanthes engelbrechtii CHOLNOKY. It became necessary to revise the original type material because of some discrepancies between the original description and figures and the current allotment of this species to the genus Planothidium. The present study confirms the transfer of A. engelbrechtii to Planothidium. A lectotype is designated from Cholnoky's original material. Valves from the type material are illustrated and discussed by means of LM and SEM micrographs.
