Identification Identification requires scanning electron microscopy.
It is one of only a very few relatively small benthic species and distinguished from them by its thecal ornamentation (foveate) in contrast to smooth thecal plates of the others. Reliable identification is best done by scanning electron microscopy.
Prorocentrum borbonicum is similar in shape to P. ruetzlerianum Faust (Faust 1990, 1997) and P. faustiae Morton (Morton 1998), but the size of cells and the thecal ornamentation are different. Prorocentrum ruetzlerianum (28-35 μm; Faust 1990) and P. faustiae (38-42 μm long; Morton 1998) are larger than cells of P. borbonicum. The thecal surfaces of P. ruetzlerianum and P. faustiae are deeply areolate and nonareo1ate, respectively (Faust 1990; Morton 1998). Our species is similar in size to P. elegans Faust and P. norrisianum Faust (Faust 1993a, 1997), but the shape and wall patterning are distinctly different. Cells of P. elegans and P. norrisianum are oval, with a smooth thecal surface (Faust 1993a, 1997). The periflagellar area of P. borbonicum is composed of eight platelets, as in several benthic Prorocentrum species (Faust 1990, 1993a, b, 1994, 1997), and offers no aid in diagnosis. The smooth surface of intercalary band of P. borbonicum is also characteristic of other Prorocentrum species (Faust 1997). The scrobiculate wall patterning of P. borbonicum is like that of P. compressum (Bailey) Abe ex Dodge (Dodge 1975; Hernandez-Becerril 1988), P. mexicanum Tafall (Faust 1990), P. caribbaeum Faust (Faust 1993a), P. maculosum Faust (Faust 1993b), and the freshwater P. foveolata Croome & Tyler (Croome & Tyler 1987). The difference between P. borbonicum and these five species resides in the shape and size of the cells and in the disposition of the valve pores. P. compressum (38-43 μm long; Hernandez-Becerril 1988), P. mexicanum (30-38 μm long; Faust 1990), P. maculosum (40-50 μm long; Faust 1993b), and P. foveolata (25-30 μm long;
Croome & Tyler 1987) are larger than P. borbonicum, and their shape is oval. Prorocentrum caribbaeum (40-45 μm) long) is larger as well, and the cell is heart-shaped (Faust 1993a). The valve pore pattern of P. borbonicum differs from that of other Prorocentrum species: for example, the arrangement of the pores is orderly in P. elegans (Faust 1993a) and P. formosum (Faust 1993b); radially arranged in P. mexicanum (Faust 1990) and P. caribbaeum (Faust 1993a); and scattered in P. maculosum (Faust 1993b) and P. norrisianum (Faust 1997). Two sizes of valve pores exist in P. borbonicum. This feature is also observed in P. emarginatum, P. mexicanum, P. elegans, P. caribbaeum, P. formosum, and P. norrisianum (Faust 1990, 1993a, b, 1997). Altogether, P. borbonicum is sufficiently different from other Prorocentrum species to warrant specific rank.
