Dicranophorus caudatus / Dicranophoroides caudatus Harring & Myers 1928
Dicranophoroides caudatus; with the conspicuous red frontal eyespots this species might be regarded as a Cephalodella species. But the forcipate mastax makes it clear that it is a dicranophorid rotifer. The special trophi structure (see beloew images) justifies a new genus for this species: Dicranophoroides (De Smet 1997). This species is also characterised by the presence of zoochlorellae. (3)

Dicranophoroides caudatus, lives at the boundary layer between detritus / mud and the water body of ponds and puddles. Like other Dicranophorids the trophi can be stretched out. (1).
