In 1880 , the diamond stingray was described twice by three American ichthyologists : as Dasybatus dipterurus by David Starr Jordan and Charles Henry Gilbert in Proceedings of the United States National Museum , and as Trygon brevis by Samuel Garman in Bulletin of the Museum of Comparative Zoology . Jordan and Gilbert 's account was published in May while Garman 's was published in October , making dipterurus ( feminine dipterura ) the correct name as it was published first . However , when Garman synonymized the two in 1913 he inappropriately gave precedence to brevis , leading to long @-@ standing confusion . Both Dasybatus and Trygon was later synonymized with the genus Dasyatis , but many authors still listed D. brevis in place of or in addition to D. dipterura . Garman also synonymized the Hawaiian stingray ( D. hawaiensis ) with D. dipterura in 1913 , which have since been followed by most authors but require more study for confirmation .
