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 cf. subacuta and Tintinnopsis sp. from Rhode River, MD and T. major from Annapolis, MD, USA
Undescribed species of Euduboscquella, infecting Tintinnopsis cf. subacuta, Tintinnopsis major and Tintinnopsis sp. (Bachvaroff et al. 2012). Identical parasite SSU rRNA sequences in all 8 cases (3 from Tintinnopsis sp., 5 from T. cf. subacuta, 1 from T. major). Close to E. crenulata. Accession number: Tintinnopsis cf subacuta: JN934990-1, JN934995, JN934998-5003, Tintinnopsis sp.: JN934994, JN934996-7, JN934992, T. major: JN934993.
Within the four parasite sequences from T. cf. subacuta, there were a total of 19 variable sites, while the four sequences from Tintinnopsis sp. from the Rhode River contained 16 variable sites (Table 2). Across all 9 individuals from the three different host morphotypes, there were a total of 27 variable sites in the parasite ITS-to-LSU regions over 1,415 bases. Parasites infecting Tintinnopsis cf. subacuta and Tintinnopsis sp. share 4 to 15 non compensatory changes among the 8 ribotypes, but no compensatory change. The T. major parasite that differed from the other Tintinnopsis species from the Rhode River by a single compensatory change in stem II. This parasite may be a separate species.

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).
 

Type species

The type species of the genus is E. crenulata.
