This chapter discusses the general morphology of the body and appendages of the Heterorhabdidae. It notes that the species can readily be distinguished from the Lucicutiidae, Augaptilidae, and any other calanoid families by the following synapomorphies: the left caudal ramus is longer than the right and normally it is fused with the anal segment; the fourth marginal seta of the left caudal ramus is unarmed and greatly elongated; the basis of the male right P5 has a large plumose inner lobe. The chapter observes that based on these synapomorphies, only the following seven genera are referable to the family: Disseta, Mesorhabdus, Heterostylites, Hemirhabdus, Neorhabdus, Paraheterorhabdus, and Heterorhabdus.

Keywords: morphology; body; appendages; Heterorhabdidae; Lucicutiidae; Augaptilidae; calanoid families; synapomorphies
