A new and abundant species of Paradoneis Hartman, 1965 is described from the vicinities of a sewage outfall in Mamala Bay, Oahu, Hawaii. This species belongs to a group of at least six Paradoneis species that have three prebranchiate segments, modified notopodial lyrate chaetae from chaetiger 3, and lack additional types of modified chaetae. Paradoneis kamaehu sp. nov. is unique among its congeners by the presence of 25–48 pairs of branchiae, reddish-brown body color, peristomium distinct dorsally, and presence of up to two lyrate notopodial chaetae. Epitokes and individuals with regenerating anterior ends are reported and the reproductive strategy of this species is discussed. The capacity of regeneration of the anterior end is reported for the first time in paraonids.
