Spiniferomonas septispina and S. enigmata, Two New Algal Species Confusing the Distinction Between Spiniferomonas and Chrysosphaerella (Chrysophyceae)

Description
Summary:Two new species of non-colonial silica-scaled chrysophytes were discovered in Ontario and were assigned to the genus Spiniferomonas (Chrysophyceae) owing to their solitary cell habit. Scale structure in the two new species is distinctive but includes features common to both Spiniferomonas and Chrysosphaerella. The use of scale structure as the main diagnostic feature to distinguish the two genera is no longer acceptable. A more expedient separation of the two genera based on cell habit (solitary vs. colonial) is proposed and includes the transfer of Chrysospharella salina Birch-Andersen and Chrysosphaerella coronacircumspina Wujek & Kristiansen to the genus Spiniferomonas as new combinations. The proposed revision is consistent with existing generic circumscriptions of other ochromonadalean forms with either solitary or colonial cell habit.
