Diagnosis

Diagnosis_Genus: Duboscquella Chatton, 1920, emend. Coats & Bachvaroff 2012. Duboscquellidae ectoparasitic on tintinnids. Trophont lacking flagella, cingulum, and sulcus; developing food vacuole during prolonged feeding. Tomont and sporocytes without double outer membrane or cyst wall. Dinokont spores with transverse flagellum set in cingulum; longitudinal flagellum extending posteriad from sulcus.

Diagnosis_Species: Duboscquella tintinnicola Lohmann, 1908, Chatton, 1920, emend. Coats & Bachvaroff 2012. Aplastidic dinospores 17--20 by 10--12 µm numbering approximately 10--24, with rounded episome and deeply cut, bi-lobed hyposome. Lacking conspicuous eyespot at base of flagella.

Body_spores_length: 17-20 µm
