From a number of partial moult series obtained by laboratory culture of plankton-caught specimens, and based on drawings from whole-mounted material, we describe all the larval instars, including the y-cypris, of a new species of Facetotecta. The mid-length constriction of the antennulary aesthetasc and the shape of the head shield separate the y-cypris in our material from all other forms of y-cyprids previously assigned to species. The morphology of the present y-nauplii and y-cypris is compared with that of previously described facetotectan larvae.
