Abstract:

Four mysis stages of a species of Gennadas, very likely G. valens, are described and illustrated, and their differences from the only described larvae of a species of this genus, G. elegans, are discussed. The larvae were collected downstream and inshore from a seamount on the continental shelf in the Florida Keys between 24.5°N, 80.7°W and 25°N, 80.3°W. Adults and juveniles of species of Gennadas have previously been reported as strong diel vertical migrators aggregated at depths of 550–950 m during the day and 75–425 m at night; and larvae have been reported as common between 50 and 100 m deep. This is the first description of larvae of a species of Gennadas other than G. elegans and the first report of larvae of a species of Gennadas at less than 50 m in depth.
