Resumen: "A new species of the harpacticoid copepod genus Echinolaophonte is described here from specimens obtained during a biological survey of Rodadero Bay, a coastal system in the Colombian Caribbean. This species has been previously recorded as E. ar miger Gurney, 1927 in di?erent geographic areas (Indian and Paci?c Oceans). The Colombian specimens recognized as E. villabonae sp. n. and true E. ar miger are deemed as distinct species based on di?erences in several features of which the shape of the rostrum and the dorsal spinous process on the prosome are among the most distinctive. These and other characters are shared by specimens recorded as E. ar miger from Caroline Islands and Australia that are now incorporated to the new species. The ?nding of the true E. ar miger, previously known only from Egypt, the Texan coast, Brazil, and possibly Bermuda, constitutes the ?rst record of this species in the western Caribbean and a regional range extension. A key to the identi?cation of the 13 known species of the genus is also provided. "
