Resumo(s)
This paper presents the description of a new species of the genus Calma (Alder & Hancock, 1855). To
date only one valid species, Calma glaucoides (Alder & Hancock, 1854), has been assigned to this
genus, which feeds exclusively upon eggs of littoral teleost fishes. New morphological and ecological
data, and review of the literature on the species attributed to this genus, lead us to conclude that there
are two distinct species previously put together under the same specific name. Calma gobioophaga new
species is described based upon consistent morphological differences, such as the diameter and position
of the eyes, the size of the propodial tentacles, and the size of the metanefridium. Whereas Calma
gobioophaga feeds on spawn of Gobius niger, Calma glaucoides feeds on eggs of Lepadogaster lepadogaster,
Lepadogaster purpurea, Lepadogaster candollei, Parablennius gattorugine, and Parablennius pilicornis.
