Harmful effect Material from Malaysia is known to produce okadaic acid (Caillaud et al. 2010). The identity of the material as P. rhathymum was confirmed by scanning electron microscopy.
Material from Florida (An et al. 2010), found in laboratory studies to produce okadaic acid, was not illustrated but was found to be almost identical in ITS sequences to the Malaysian material. It therefore most likely represents P. rhathymum.  [details]

Status  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 valves, some of which are arranged in radiating lines towards the lateral sides. P. mexicanum is from the marine phytoplankton and has no radiating lines of trichocyst pores, the pores are scattered on the valve surface. See Hoppenrath et al. (2014) for further information on P. rhathymum. Cells of P. rhathymum are smooth are smooth (young cells) or rugose (old cells, see Faust 1990). The latter were described by Gomez et al. (2017) as P. steidingerae by Gomez et al. (2017). This name is a synonym of P. rhathymum[details]
