Harmful effect A strain from the Western Mediterranean Sea was found to produce small amounts of maitotoxin, the ciguatoxin 54-deoxyCTX1B and gambieric acid A (Laza-Martínez et al. 2015). Strains from the South Pacific also demonstrate low production of MTX-3 (Munday et al. 2017; Larsson et al. 2018). [details]

Identification In dorso-ventral view, the contour of F. ruetzleri is narrow, while Fukuyoa paulensis is more rotund and more similar to F. yasumotoi. Fukuyoa paulensis is intermediate in size between F. yasumotoi and F. ruetzleri. According to Litaker et al. 2009 the cell dimension of F. yasumotoi is depth 57 ± 5 (49–67) μm, width 52 ± 5 (43–60) μm and length 62 ± 4 (54–68) μm and for F. ruetzleri is depth 45 ± 3 μm (range 42–55 μm), width 37 ± 3 (31–42) μm, length 52 ± 5 (45–59) μm. The dimension of our new species is depth 50 ± 3 (45–56) μm, width 45 ± 2 (41–48) μm, and length 56 ± 3 (51–62) μm. Litaker et al. proposed a dichotomous tree for Gambierdiscus, where globular cells with <42 μm cell width corresponded to F. ruetzleri . Based on the size, the smaller specimens of F. paulensis fall into the size range of F. ruetzleri, and most of the specimens are closer to F. yasumotoi. However, the overlapping in the size range between the species suggests the need to use other morphological character as diagnostic character. Plate 1' of F. paulensis is broader and occupies a proportionately larger portion of the epitheca than in the other species. Plate 1' is nearly rectangular in F. yasumotoi or narrow pentagonal in F. ruetzleri, while broad pentagonal in F. paulensis. Consequently, the main diagnostic morphological character is that F. paulensis has a broad plate 1' in comparison to the narrow plate 1' of the other globular species. Plate 2' is more elongated and occupies a larger area with respect to plate 3' than in other globular species. Plate 3' is more reduced in F. paulensis and the five-sided contour is less apparent because the suture with plate 4''' is shorter. Posterior intercalary plate (1p) is an elongated pentagon in F. paulensis, broader than in the other globular species. Consequently, the tabulation (mainly the apical series) is the main diagnostic morphological character. [details]

Description Cells are globular in shape with average depth 50 ± 3 (45–56) μm, width 45 ± 2 (41–48) μm, and length 56 ± 3 (51–62) μm, and an average width-to-depth ratio of 1.2. Cells were broad in lateral view. Epitheca is dome-shaped and hypotheca slightly larger than epitheca. Thecal pores are round and numerous. Plate formula Po, 3', 7'', 6c, 7s, 5''', 1p, and 2''''. Apical pore plate is centrally located in the epitheca with a long-shank fishhook-shaped slit. First apical plate (1') is the biggest apical plate, broad and five-sided. Plate 2' is long, curved or straight in the suture 2'/3''. Plate 3' is broad and intermediate in size. Plate 1'' is minuscule and 7'' is also small, both lying in the wedge-shaped posterior end of plate 1'. Plates 3'' and 6'' are the biggest of the epitheca, and the 2'', 4'' and 5'' are intermediate in size. The descending cingulum was displaced twice its width. The sulcus is deep and excavated, with two prominent posterior sulcal plates. Plates 1''' and 5''' are small, plate 3''' median in size, and plates 2''' and 4''' are the largest of the hypotheca. The rectangular plate 1'''' is small, and folded onto the left side of the sulcus. Plate 2'''' is forked and invades the base of the sulcal hollow. There is one intercalary posterior plate (1p), with the shape of an elongated pentagon situated between plates 2''' and 4'''. Nucleus situated in the hypotheca. The cells contain numerous small ellipsoidal plastids with a brownish pigmentation. [details]

Harmful effect A strain from the Western Mediterranean Sea was found to produce small amounts of maitotoxin, the ciguatoxin 54-deoxyCTX1B and gambieric acid A (Laza-Martínez et al. 2015). Strains from the South Pacific also demonstrate low production of MTX-3 (Munday et al. 2017; Larsson et al. 2018). [details]

Identification In dorso-ventral view, the contour of F. ruetzleri is narrow, while Fukuyoa paulensis is more rotund and more similar to F. yasumotoi. Fukuyoa paulensis is intermediate in size between F. yasumotoi and F. ruetzleri. According to Litaker et al. 2009 the cell dimension of F. yasumotoi is depth 57 ± 5 (49–67) μm, width 52 ± 5 (43–60) μm and length 62 ± 4 (54–68) μm and for F. ruetzleri is depth 45 ± 3 μm (range 42–55 μm), width 37 ± 3 (31–42) μm, length 52 ± 5 (45–59) μm. The dimension of our new species is depth 50 ± 3 (45–56) μm, width 45 ± 2 (41–48) μm, and length 56 ± 3 (51–62) μm. Litaker et al. proposed a dichotomous tree for Gambierdiscus, where globular cells with <42 μm cell width corresponded to F. ruetzleri . Based on the size, the smaller specimens of F. paulensis fall into the size range of F. ruetzleri, and most of the specimens are closer to F. yasumotoi. However, the overlapping in the size range between the species suggests the need to use other morphological character as diagnostic character. Plate 1' of F. paulensis is broader and occupies a proportionately larger portion of the epitheca than in the other species. Plate 1' is nearly rectangular in F. yasumotoi or narrow pentagonal in F. ruetzleri, while broad pentagonal in F. paulensis. Consequently, the main diagnostic morphological character is that F. paulensis has a broad plate 1' in comparison to the narrow plate 1' of the other globular species. Plate 2' is more elongated and occupies a larger area with respect to plate 3' than in other globular species. Plate 3' is more reduced in F. paulensis and the five-sided contour is less apparent because the suture with plate 4''' is shorter.
