Uniporodrilus purus, new species, from subtidal sand near Pensacola in northwestern Florida, is described. It is distinguished from all congeners by lacking penial setae. A most parsimonious cladistic hypothesis of the species of Uniporodrilus (subfamily Phallodrilinae) is presented. It suggests a basal dichotomy of the genus, with U. purus and U. granulothecus, both subtidal species, constituting one clade characterized by unpaired male and spermathecal pores, and the four remaining species, all intertidal, representing another clade characterized by a high number of somatic setae and enlarged pharyngeal cavity.
