Diagnostic Description
provided by Harmful Phytoplankton Project
Body elongate, conical, posterior gradually tapering, 90 (35-125) µm long, 35 (25-90) µm wide (Fig 1,2).; Oral cavity acentric; 15 (14-16) EPks and 3 (1-5) IPks; EPZ and IPZ not completely separate: 4-5 IPks are separate, the others are extensions of EPks (Fig 1a,5,7b); EPZ is a closed circle with cilia of unequal length (Fig 7a,b,8); paroral kinety situated beneath and close to the EPks.; 12-16 longitudinal somatic kineties, extend along entire cell length (Fig 1,4,6) with 20-50 dikinetids, both kinetosomes ciliated, cilia 3-5 µm long; incomplete somatic kineties can occur ? lacking either posterior or anterior ends.; Two macronuclei, spheroid to ovoid (Fig 1,5,6).
