 |
 |
| Synchaeta tremula: specimen from (2) , slightly compressed. Two images from the same specimen, different focus planes. Upper image: Focus plane on two red frontal eyespots. Nogrady/ Segers (2002) mention that (only?) marine or brackish specimens of the genus Synchaeta may have such frontal eyespots, but the specimens here are from fresh water. Lower image: focus plane on cervical eyespot. (2) |

 |
| Synchaeta tremula: specimen from (4), lateral view of the right side of a specimen from (4). Focus plane on the peripheral muscles and the right lateral antenna (arrowhead) with connecting nerve cells. |
