Taxonomy The species
Taxonomy The species was suggested by Gomez et al. (2017) to be a synonym of Prorocentrum mexicanum. However, the two species differ in both morphology and ecology. P. rhathymum is a benthic marine dinoflagellate with a characteristic pattern of trichocyst pores on the thecal plates, some of which are arranged in radiating lines towards the lateral sides. P. mexicanum is from the marine phytoplankton and it is unclear from the original description whether it has radiating lines of trichocyst pores (likely not), the pores are scattered on thecal surface. See Hoppenrath et al. (2014) for further information on P. rhathymum. Further studies of the species complex (P. mexicanum, P. rhathymum, P. steidingeae) are needed to clarify species delimitations and synonymy. [details]

Description Clearly distinct from P. rhathymum, according to Cortés-Altamirano and Sierra-Beltrán (2003). Cells 30–40 μm in length and 20–30 μm in width. Valval pores radiating and a line of pores along the margins. From Lassus et al. 2016.[details]
Harmful effect P. mexicanum is included in Lassus et al.(2016) as harmful. It is mentioned as producing haemolytic toxins of unknown nature. However, as the material on which this information is based is benthic, it is likely that the information relates to Prorocentrum rhathymum, not P. mexicanum.
Lassus et al. (2016) further mention that P. mexicanum produces FAT. However, the information referred to is from a congress abstract and the organism was not identified further. Its identity is therefore somewhat uncertain (Tindall et al. 1981).
True P. mexicanum needs to be refound and its harmful potential to be re-examined. [details]
