The first report of the species was from the Gulf of Nicoya Escherbothrium molinae was described by Berman taxa and the bifurcating structure of the medial bothridial and Brooks (1994) based on 35 specimens taken from septa of E. molinae. Therefore, they placed it into the several individuals of Urotrygon chilensis (Günther, 1871) family Triloculariidae. Others have suggested that the (Chondrichthyes: Myliobatiformes: Urolophidae), the genus should be moved to the Rhinebothriinae, but formal Chilean round ray, collected in the Gulf of Nicoya and taxonomic studies of this question are still wanting. the Guanacaste coast, Costa Rica.
