I found the specimen of Lecane tenuiseta shown below in October 2004 in the Simmelried. I was able to photograph it in the extended state. In most cases, however, the specimens retracts into the lorica under the coverslip. Therefore the drawings of Lecane species almost always show contracted animals. Also the data for the dimensions refer to contracted animals.

For the identification of Lecane tenuiseta I rely mainly on the very short description of this species as well as on the drawings of Carlin (s. above), who has accurately reproduced the sculpturing of the dorsal and ventral lorica. Very characteristic are two Y-shaped structures in the anterior third of the ventral lorica, which are also well visible in the living specimen (s. fig. 1 b). These two Y-shaped structures are separated by an approximately parallel-sided structure (s. fig. 1 b). The lorica of Lecane tenuiseta also has dome-shaped structures, which can also be easily seen (s. fig. 1 a). At the posterior end, there is a hourglass-shaped structure on the ventral side (s.  fig. 1 a and the right drawing above). The toes of Lecane tenuiseta are quite long and the tapered claws are said to be half that length. In my specimen the ratio was 22 µm : 14 µm (s. fig. 1 a), which corresponds to 2 : 1.2.
