Diagnosis

Diagnosis_Genus: Euduboscquella Coats & Bachvaroff 2012. Euduboscquellidae with trophont episome as disc-shaped shield bordered by a perinematic ring. Lamina pharyngea extending from perinematic ring into trophont cytoplasm. Food vacuole formed as trophont emerges from host giving rise to extracellular tomont. Multiple spore morphotypes possible, including dinokont and non-dinokont cells. Individual infections producing only one type of spore.

Euduboscquella parasites infecting Tintinnopsis sp. from Villefranche-sur-Mer (France)
Undescribed species of Euduboscquella, infecting Tintinnopsis sp. (Bachvaroff et al. 2012). Known from SSU and ITS sequence from 2 individual infected host cells (Bachvaroff et al. 2012). Accession number: JN934984. Close to E. crenulata.
 

Etymology

Genus name is derived from the Greek eu- (= well, normal) and the genus name Duboscquella. The combination is intended to imply organisms truly related to the parasite studied by Duboscq and Collin (1910).
