En este trabajo se describe la morfolog赤a del epipodio del caracol marino Prisogaster niger. En esta especie el epipodio est芍 conformado por un complejo de estructuras entre las cuales los l車bulos del cuello, rebordes epipodiales, tent芍culos epipodiales y papilas epipodiales constituyen conspicuos caracteres. El estudio de la morfolog赤a del epipodio revel車 potenciales autapomorf赤as de valor diagn車stico para la subfamilia Prisogasterinae. In this work the epipodium morphology of the marine snail Prisogaster niger is described. In this gastropods the epipodium includes a complex of structures among which the neck lobes, epipodial ridge, epipodial tentacles and epipodial papillae constitute the most remarkable characters. Although these features are commonly found among trochoidean taxa, the observation of the epipodium, compared with the literature, revealed potential autapomorphic characters of diagnostic value for the genus and the subfamily Prisogasterinae, like epipodial lamellae and epipodial tuft.
