GREENFIELD Department of Biological Sciences Northern Illinois University and Research associate. Division of Fishes Field Museum of Natural History ABSTRACT A new chaenopsid blenny, Emblemaria hyltoni, is described from five male speci-mens taken off Dixon Cove, Isla Roatan, Honduras. The remarkably prolonged, filamentous first dorsal-fin spine, which in length exceeds two-thirds of the standard length, distinguishes this species from all other species of Emblemaria. E. hyltoni best agrees with E. caldwelli Stephens, 1970 and E. piratula Ginsburg and Reid, 1942, in the possession of only two obvious segmented pelvic-fin rays, but differs from them in numerous other features. New material of E. caldwelli is reported from Belize and new material of E. piratula is reported from off western Florida. ABSTRACTO Se describe una nueva especie de la familia Chaenopsidae, Emblemaria hyltoni, de cinco especimenes colectados cerca de Dixon Cove, Isla Roatan, Honduras. E. hyltoni se distingue de las otras especies del genero por su primera espina dorsal notablemente prolongada, y su altura sobrepasando dos terceras de la longitud estandar. E. hyltoni se asemeja a E. caldwelli Stephens 1970, y a E. piratula Gins-burg y Reid 1942, por su aleta ventral con solamente dos obvios radios segmentos, pero puede distinguerse de esas dos especias por otras caracteristicas. Tambien, se reportan nuevos ejemplos de E. caldwelli desde la costa de Belize, y de E. piratula desde la costa oeste de Florida.
