Samples: Moen2_ Dictyota

Dimensions: 61.7–92.6 μm long, 42.2–56.7 μm wide; 8–9 striae in 10 μm, 12–14 areolae in 10 μm.

Comments: The valve and lyre shape of the specimen form Moen Island, are similar to L. clavata var. caribaea ( Siqueiros-Beltrones et al. 2017) , but the valve size of our specimens are larger than L. clavata var. caribaea (34–88 μm long, 20–30 μm wide), and the number of striae is sparser than L. clavata var. caribaea (11–13 striae in 10 μm).
