Identification Remarks: P. faustiae is extremely similar to P. concavum, having the same cell shape, surface ornamentation, size range, and pyrenoid. The differences described are mainly the number of periflagellar platelets. However, on the images provided only 8 or 9 platelets are visible. The marginal pores mentioned in the original description is not a convincing difference. This species is in need of morphological reinvestigation to clarify whether it is conspecific with P. concavum, making it a synonym.
In the light microscope free-swimming cells cannot be distinguished from Prorocentrum malayense, a species that can co-occur (Verma et al. 2019).

Description Broad oval to ovoid cells with central pyrenoid (starch ring). Reticulatefoveate thecal surface with scattered pores becoming more dense towards the margin. Plate centre devoid of pores and in some cells also devoid of depressions. The periflagellar area is V-shaped and a small platelet list can be present in some cells. Eight or nine platelets. The round to oval nucleus is located posteriorly.  [details]

Harmful effect Reported to produce OA, OA diol ester, DTX1 and FAT (Hu et al. 1993, Tindall et al. 1984, 1989). Quod et al. (1995) found that crude methanol extracts are not toxic to mice. [details]

The differences described are mainly the number of periflagellar platelets. However, on the images provided only 8 or 9 platelets are visible. The marginal pores mentioned in the original description is not a convincing difference.
