The rare and very small belly-hardy L. minor was already presented by me in the forum: https://www.mikroskopie-forum.de/index.php?topic=38615.0 .
One of the animals found had reached its postpathenogenetic (hermaphrodite) phase and was already carrying an X organ and sperm bundle:
L. minor chaetifer: above dorsally with smooth scales typical of Lepidodermella; middle in cross section with X-organ and sperm bundle; below ventral scaling with distinct terminal plates (©️ Ole Riemann).
In Sima Marsh the somewhat divergent subspecies Lepidodermella minor chaetifer was found, differing from the species L. minor minor by a pair of spines at the base of the toes:
L. minor chaetifer: the pair of spines at the base of the toes is characteristic of the subspecies chaetifer
Another striking feature of this species is the single tooth projecting asymmetrically from the oral cavity:
