Soil Organisms; Dileptid

Post by SW_Perspective »

This is from a soil sample using a non-flooded culture technique. The organism is about 750 microns long. Long proboscis with oral apparatus at the base. Extrusomes along proboscis. Nucleus visible in all images. I'm guessing Dileptus as genus level ID based on what I can see of the nucleus. I found the following reference helpful.

Really nice images! Members of the genus Dileptus have a macronucleus made up of scattered nodules (>50). This critter has a long, cylindroidal macronucleus (possibly in two segments). That puts this in the family Dimacrocaryonidae (Monomacrocaryon, Dimacrocaryon, Rimaleptus).
