This chapter describes Disseta which is the most primitive genus in the Heterorhabdidae. It notes that it can be distinguished from the other genera of the family by such primitive features as the inner marginal setae on all exopodal segments of A2, a large number of teeth and setae on Md, a relatively short exopod of Mx1, relatively unspecialized setae and spines of Mx2, a large number on the coxa of Mxp, and an outer seta on the basis of P1. The chapter describes the female and male of this species. It reports that Disseta palumbii has been found to be a common member of the circumglobal bathypelagic community, mainly in the tropical and temperate zones of the world's oceans, since its original discovery at 16 degrees N, 166 degrees E in the central Pacific.
