Males of the two known species of Mormonilla Giesbrecht are described in detail for the first time. They have reduced or vestigial mouthparts and are probably non-feeding. Males have a single testis and produce a single spermatophore. Male antennules are geniculate. A system of probable segmental homologies for the antennulary segments is proposed and the supporting evidence for this system discussed. Females carrying egg sacs are reported and figured for the first time. Mormonilla is unusual amongst copepods in producing paired egg sacs from a common medial genital aperture.
