Notes
Nootkadrilus gen. nov. is characterized by an ental atrial modification, modified penial setae, and stalked posterior prostate glands. Nootkadrilus compressus sp. nov., N. verutus sp. nov., N. grandisetosus sp. nov., N. hamatus sp. nov., N. gracilisetosus sp. nov., and N. frigidus (Brinkhurst, 1971) comb. nov. are separated by shape and numbers of penial setae as well as by details of the atrial and spermathecal systems. Discordiprostatus gen. nov. is established for D. longisetosus (Brinkhurst and Baker, 1979) comb. nov. which is characterized by an anterior diffuse prostate, modified penial setae, and stalked posterior prostate glands. Both Nootkadrilus gen. nov. and Discordiprostatus gen. nov. are included in the subfamily Phallodrilinae. The definition of the Phallodrilinae is modified to include species with both diffuse and stalked prostate glands.
