3.1.3 Alexandrium globosum Nguyen-Ngoc et Larsen ( Figures 12–19 View Figures 12–19 )

References: Nguyen and Larsen 2004, 93, pl. 7, figs 1–8; Alvarado et al. 2015, 3, figs 2 a–c.

Solitary cells, ovoid, slightly depressed longitudinally, epitheca and hypotheca about the same proportion ( Figure 12 View Figures 12–19 ), wide and excavated cingulum ( Figures 13 and 14 View Figures 12–19 ), smooth theca ( Figures 14–17 View Figures 12–19 ) with scattered pores; the nucleus is central, to the left side ( Figure 12 View Figures 12–19 ). The first apical plate (1′) is not in connection with Po, is asymmetrically pentagonal and has a small ventral pore between this plate and 4′ ( Figures 13 and 15 View Figures 12–19 ), whereas 2′ and 4 ʹ are large plates, and plate 6″ is rhomboid ( Figure 15 View Figures 12–19 ). Po is elongate and more triangular ( Figure 17 View Figures 12–19 ). The posterior sulcal plate (Sp) is oblique pentagonal, longer than wide, with no apparent pore ( Figure 18 View Figures 12–19 ). Some particular plates of the epitheca, cingulum and sulcus were also observed ( Figure 19 View Figures 12–19 ).

Measurements: 35–42 μm L, 40–45 μm W (Table 1).

Toxicity: this species is not considered to be toxic ( Long et al. 2021).

Distribution: in the Gulf of Tehuantepec.
