Original description
“testula styliformis a ventre linearis, lateribus rectis, apicibus arcte constrictis late rotundatis.”
Krammer (1992[1], pl. 32, fig. 10) [reproduction of Ehrenberg’s published figure (1843, Tafel I, Fig. IV:1)] defined an “iconotype” for Pinnularia microstauron. Since we found the specimen used by Ehrenberg to describe the species, we designated it here as lectotype of the species. Stauroptera microstauron was described for two samples from Brazil and Canada (Labrador) (Ehrenberg 1843[2], p. 387). However, we did not find any mentioning of Stauroptera microstauron in the legends of the mica from Labrador (250509 to 250516). Therefore, we defined the lectotype from the material from Brazil.
