Original description: Cellula parva, nuda, elliptica, latitudine paulo longiore, forte compressa, dorsiventrali, duobus flagellis, altero circa 1/3 cellulae longitudinis, altero 1/2—2 plo longiore, utroque in depressione parva sub apicem in latere ventrali inserto; a latere visa anguste ovata, parva depressione subapicali in latere ventrali praedita ubi flagella inserta sunt; a vertice visa elliptica; 2 chromatophoris, luteoviridibus, parietalibus et lateralibus, latus ventrale fere tegentibus, sed non nisi supra minimam partem lateris dorsalis extendentibus; plerumque cum 2 granulis refringentibus conspicuis et caeruleis, saepe forma irregularibus et interdum aut uno aut pluribus globulis magnis refringentibus. Desunt stigma et vacuola contractilia.

Cell small, naked, elliptical, slightly longer in width, perhaps compressed, dorsiventrally, with two flagella, one about 1/3 of the cell length, the other 1/2-2 times longer, both inserted in a small depression under the apex on the ventral side; seen from the side narrowly ovate, provided with a small subapical depression on the ventral side where the flagella are inserted; seen from the top elliptical; 2 chromatophores, luteo-green, parietal and lateral, almost covering the ventral side, but only extending over a small part of the dorsal side; usually with 2 conspicuous and blue refracting granules, often irregular in shape and sometimes with one or more large refracting globules. Stigma and contractile vacuole are absent.

Morphology:
Motile cells are ovate to oblong and slightly metabolic with a golden-green parietal plastid. The anterior flagellum is visible and bears hairs and knob scales. A well-developed haptonema emerges adjacent to the anterior flag- ellum, sometimes with fine filipodia. The vestigial posterior flagellum is reduced to the axoneme structure and is covered by small clavate knob scales, like the entire cell body external to the plasma membrane. A pyrenoid and an eyespot were not observed. One or two plastids are present with a parallel helicoidal arrangement of thylakoid lamellae as in E. gayraliae. [Bendif et al. 2011]
