Heteronema trispira is a spirally twisted flagellated euglenoid from the genus Heteronema first described by Olexandra Matvienko in 1938.[1][2]
Description
Heteronema trispira has a spindle-shaped body up to 130 µm long, twisted into a spiral with three characteristic counterclockwise turns. It has a central nucleus, two long flagella and an apparently smooth periplast that tapers to a "snout-like" extension. The cell is filled with very small paramylon grains.[2]
One specimen was described as containing phagocytosed algae.[2]
Habitat and range
H. trispira is rare,[3]:5 known only from a few isolated observations since 1938.[2] Observations have been recorded from wetlands in Ukraine,[1][4] Bulgaria[5] and Germany.[2] One cell was recorded from a freshwater lake in Florida.[3]:17
