This article is about a genus of protists. For the genus of insects alternatively known as Diplonema, see Trichomyia.

Characteristics

Diplonema feature two short flagella of equal length and two subapical openings. Most are free living, but there have been reported cases of infection in clams and sudden decomposition of aquarium plants. It was described initially in 1913 and later rediscovered in the 60s and called Isonema, wrongly classified among euglenids.^[2][3]
