Description of Nannoeca minutaThe lorica about 4.5-7 microns long and tightly surrounds the protoplast and the rather short collar, whereas the flagellum (5-10 microns long) projects over the lorica in a conspicuous manner. The distinct hairpoint is also visible under the light microscope. The conical lorica is constructed from about 25 costal strips arranged in 6-10 longitudinal costae and two transverse costae. One transverse costa is located at the anterior opening of the lorica and the other is positioned in the mid-lorica region. The distance between the two transverse costae corresponds with the half-length or (less frequently) approximately the entire length of an anterior longitudinal costal strip.
