    Type material of Melosira sculpta (Ehrenberg) Kutzing from the Ehrenberg Collection was studied using light (LM) and scanning electron (SEM) microscopy. Comparison with Pseudoaulacosira moisseeviae (Lupikina in Brattseva etal.) Lupikina & Khursevich showed that they have very similar valve morphologies and should both belong to Pseudoaulacosira Lupikina & Khursevich. However, the species differ morphologically in several characters and so a new combination, Pseudoaulacosira sculpta (Ehrenberg) Usoltseva & Houk comb. nov. is proposed. Morphological and ultra-morphological features of this species are presented and discussed, including the presence of a septum.
