Type locality. Trindade Island , Espírito Santo, Brazil
Diagnosis (modified from Alitto et al. 2019). Disc (interradial regions) covered by short spines; radial shields triangular, with uniform coverage of short spines; dorsal arm plates fan-triangular, with a prominent medial ridge; ventral arm plates heart-shaped, with proximal edge straight and concave distally.
Remarks. A complete description for this species was recently provided with the designation of a neotype and characterization of juvenile specimens ( Alitto et al. 2019). Alitto et al. (2019) stated that diagnostic characters of O. trindadensis include the morphology and coverage of the disc (pentagonal and with small spines; see Fig. 7A View FIGURE 7 from Alitto et al. 2019), morphology of the dorsal arm plates (fan-triangular and with a medial ridge; see Fig. 7F View FIGURE 7 from Alitto et al. 2019), and number and morphology of arm spines (8–11 long, vitreous and denticulate spines; see Figs. 7F, G View FIGURE 7 from Alitto et al. 2019). We analyzed specimens studied by Alitto et al. (2019) and other important character are related to the morphology of the ventral arm plates, that is cordiform in profile (see Fig. 7G View FIGURE 7 from Alitto et al. 2019). The combination of these characters allows to distinguishes O. trindadensis from all congeners.
Besides Tommasi (1970) and Alitto et al. (2019), only Lima & Fernandes (2009) recorded O. trindadensis but they gave no description or illustrations. This report was based on a monograph entitled “ Ofiuróides (Echinoder- mata: Ophiuroidea) dos recifes de Suape e da área de influência do complexo industrial portuário ” ( Lima 2002), that was not formally published. Specimens analyzed by Lima (2002) have not been deposited in any zoological collection (Lima E.J.B., personal communication), thus preventing further studies to validate the occurrence of O. trindadensis in northeast Brazil
Distribution. Western Atlantic: Brazil (Espírito Santo) ( Tommasi 1970; Alitto et al. 2019).
