Fig. 1. Map of the study sites in the Fernando de Noronha Arquipelago (FNA). The darker lines indicate the 20m and 50m isobaths. Inside the thinner line, there is the Marine Protected Area (MPA), while outside it, there is the Environmental Protection Area (EPA) for sustainable use. Both areas comprehend the land and insular shelf up to 50m isobaths. Circles indicate the sampling locations where focal-animal, ad libitum and intensive search methods were used; triangles indicate the sampling locations where only the intensive search method was used (see Material and Methods).

Figure 2 in Notes on the origin of Müller and Henle's illustration and type material of the blue-spotted maskray Neotrygon kuhlii (Myliobatoidei: Dasyatidae)

Figure 2. – Vanikoro maskray (raie bleue; foro; Raia coerula), dorsal side. Original watercolour by J.R.C. Quoy executed at Vanikoro in 1828, during the Astrolabe expedition (Dumont d'Urville, 1833); p. 89 of Quoy and Gaimard field notes assembled as MS 840 at Bibliothèque centrale du MNHN, Paris (Bauchot, 1994). Quoy represented ocellated blue spots (N = 14), dark-brown spots (N = 13), dark speckles (N = 3), and lighter-brown scapular blotches (N = 2, one on each shoulder).

FIGURE 8 in How many lineages are there of the stingrays genus Hypanus (Myliobatiformes: Dasyatidae) and why does it matter?

FIGURE 8 | Neighbor-Joining tree based on mt-co1 from samples identified as Hypanus americanus, H. berthalutzae, H. rudis and H. longus, with H. guttatus as an outgroup. Nodes' numbers correspond to bootstrap values in percentage; only those higher than 85% are shown. Examined vouchers with an asterisk.

FIGURE 4 | Candidate species of the clade Hypanus say species complex (Clade C), according to five lineage delimitation analyses using the mtDNA. Possible species found in each analysis are portrayed as colored boxes in columns. In blue, H. say; red, H. aff. say. The same colors are used to represent sampled specimens in the map to the right: H. say, blue circles in USA's Eastern coast; H. aff. say, red circles in Gulf of Mexico. Blue star is the holotype location of the valid species, which was not sampled, in USA's Northeastern coast.
