ABSTRACT

The sergestid genus Sergestes is restricted in definition, and five new genera erected: Allosergestes, Deosergestes, Eusergestes, Neosergestes, and Parasergestes. These are defined in terms of 23 morphological characters, including features of the appendages, luminescent organs, and petasmata. The species belonging to each are listed, and the type species for each designated. Diagnoses for the remaining genera in the family, Acetes, Peisos, Petalidium, Sergia and Sicyonella are supplied. A key to the 11 currently recognized sergestid genera is provided.
