| Philodina roseola; swimming specimen. Morphotype with short spurs (see below). |

| Philodina cf roseola; whirling; lateral view. Focal plane on the cilia of the buccal field/ buccal tube. There are two different pairs (left and right side) of ciliary fields generating different water currents. The arrows indicate the direction of the metachronal waves of these cilia, not the direction of the water flow. Although the direction of the metachronal waves indicated by the green arrow is to the dorsal side, the water flow is to the ventral side. Ingested particles in this area are transported outwards. The blue arrow marks the pair of ciliary fields that create a current towards the mastax. The white line marks the plane of the optical transect in the lower left image. The same behavior of the coronal cilia could be observed and documented for Philodina alata. |

| Philodina cf roseola; anterior part, whirling; dorsoventral view, different focal planes. Upper left: focal plane on the rostrum and dorsal antenna (1). Upper right: fovcal plane on the upper lip (2). Lower left: optical transect on the plane of the buccal tube. The arrows mark the direction of the metachronal waves of the different ciliary arrangements. Orange: dexioplectic waves of the trochal cilia (counter-clockwise in frontal view); pink: 1. dexioplectic movement of the cilia of the right cingulum (clockwise in frontal view; on the left side in this image); 2. laeoplectic movement of the cilia of the left cingulum (counter-clockwise in frontal view; on the right side in this image); green: metachronal movement of cilia of the buccal field towards the dorsum; effective stroke directed ventrally; blue: metachronal movement of cilia of the buccal tube towards the mastax; effective stroke directedto the mastax (1). Lower rigt: focal plane on the cilia of the cingulum / lower lip. (1) |

| Philodina roseola; ventral view of the anterior part of a creeping specimen. The image may show the openings of the ducts of the retrocerebral organ through which the attachment of the rostrum while creeping is enabled. |

 |
| Philodina roseola; foot (specimen from (1); dorsal view of relative short acute spurs with interspace; spur-bearing segment width (SSW): ≈9µm; spur length (SL: ≈5µm; spur base width (SBW): ≈3µm; interspace: ≈4µm. |
