Abstract

Intromugil annakohnae n. sp. is described based on specimens recovered from the intestine of Mugil liza Valenciennes (Mugilidae) from the coast of Rio de Janeiro State, Brazil. Intromugil annakohnae n. sp. differs from I. mugilicolus by having a smaller body (0.70–1.90mm compared to 2.54–2.77mm), larger eggs (82–105 x 45–72 compared to 60–80 x 40), and by the presence of vitelline follicles in the post-testicular space. It differs from I. simonei in the size of body, being smaller (0.70–1.90mm by 0.30–0.62mm compared to 2.11–2.56mm by 0.80–0.91mm), in the shape of oral sucker, which is subterminal and rounded in the new species, instead of terminal and cupshaped, and in I. annakohnae n. sp. the vitellarium extending further anteriorly beyond the testis, reaching the posterior margin of ventral sucker in some specimens, rather than surrounding the testis as in I. simonei.
