Resurrection and redescription of Verrill, 1872 (Hirudinida, Glossiphoniidae) with a phylogeny of the genus .

(Verrill, 1872) is resurrected and redescribed based on morphological and molecular data from specimens of the type locality (New Haven County, Connecticut, USA) that demonstrate it is distinct from North American , European , and . is characterized by having dark chromatophores on the dorsal surface arranged lateral to patrilaterally and medially as a thin line or interrupted thin line along with three pairs of eye spots (with the first pair closest together), six pairs of crop ceca, and a united gonopore. Additional sampling of specimens of the genus is needed to understand its phylogeny especially as many species have not been collected since their description.
