Abstract

Cabra is a genus of marine thecate sand-dwelling dinoflagellates that is poorly known and of which only two species are described, C. matta and C. reticulata. In one fixed sample collected in 2007 in South Brittany, both of these species were recorded, together with a new third one. Cells of the three taxa were isolated and their morphology was characterized using scanning electron microscopy. New features previously unseen in C. matta were observed including the presence of a dense group of pores on the first antapical plate and the existence of pores of two different size classes on thecal plates. Cabra aremorica sp. nov. is 37–40 µm long and 31–38 µm deep and possesses a thecal pattern very similar to the other species described in the genus. However, C. aremorica differs from them by its overall ornamentation consisting in shallow alveolae, its polyhedral shape, and its very atypical apical pore complex. Observations of the third cingular plate c3 on the three Cabra species revealed the presence of a narrow extension that lays vertically and borders the ‘x’ (5″) plate on the ventral side of cells, which appears to be a constant feature in the genus. This fact not previously reported is crucial for the interpretation of the plate pattern and is very peculiar among dinoflagellates.
