Dicranophorus hauerianus var: dorsoventral view; focus plane on the ciliary field of the head and the conspicuous toes. The specimens from this location (Brittany) differ in certain traits from the species described in the literature up to now. For instance the specimens from this sample do not live as epibionts on crustaceans as it is reported for D. hauerianus, D. cambari and D. siedleckii. |

| Dicranophorus hauerianus var.: lateral view. The arrow points to one of two diatoms that are in the stomach of this specimen. In contrast to the descriptions for Dicranophorus hauerianus, Dicranophorus cambari and Dicranophorus siedleckii (which are all reported to feed on ciliates and rotifers) the specimens from this sample were all feeding on algae/ diatoms although rotifers (e.g. Keratella, Lepadella etc.) were rather abundant. |

| Dicranophorus hauerianus var: left image: head in ventral view; focus plane on the ciliary field. Right: foot with conspicuous foot glands and toes. |
| |
 |
| Dicranophorus hauerianus var.: forcipate trophi. The yellow rectangle marks a structure that might be the epipharyngeal plate (see right image below). (in the lower part of the image are diatoms). |
|
|
| Dicranophorus hauerianus var.: left image:forcipate trophi; focus plane on the rami. The inner margins of the rami have 5 teeth which increase in size fulcrum-wise. Right image: focus plane on another dentated structure (epipharyngeal plate?) with 4 teeth each. |

 |
| Dicranophorus hauerianus var.: incus of forcipate trophi of specimen from (3) . Also visible (upper left) are the epipharyngeal structures. |

 |
| Dicranophorus hauerianus var.: another specimen from Brittany. This free living morphotype has been found in the year 2024 in 4 brooks that were several tens of kilometers away from each other. The intestinum is always filled with diatoms.(3) |
| |
 |
| Dicranophorus hauerianus var.: specimen from (4), slightly compressed. Focal plane on the vitellarium with 8 nuclei (which is in contrast to the observation of Wulfert (1937). |
| |
 |
| Dicranophorus hauerianus var.: lateral view of specimen from (5), stomach full of diatoms. |
| |
  |
| Dicranophorus hauerianus var.: two images of the forcipate trophi, different focal planes. |
