Surirella barrowcliffia. LM micrographs from the type locality Photos 1-4 and 10 individuals from the Pilica River. Photos 5-9 – individuals from the Hustedt collection (Photos 5-7 No. H 76878 – slide number 143/33; Photo 8 No. H 93219 – slide number X7/12; Photo 9 No. H 83213 – slide number X1/37). Scale bars = 10 µm Photo 1 shows isopolar valves (marked with red arrows) and a narrow-lanceolate hyaline axial area (marked with yellow arrow).
