The gutless members of the subfamily Phallodrilinae are taxonomically revised and generically split off from their gut-bearing relatives. Inanidrilus Erséus, 1979, a much modified definition of which is presented, comprises the species leukodermatus (Giere, 1979) comb.n., speroi sp.n., fijiensis sp.n., bonomii sp.n., carterensis sp.n., gustavsoni sp.n., wasseri sp.n., scalprum sp.n., belizensis sp.n., aduncosetis sp.n., vacivus sp.n., triangulatus sp.n., ernesti sp.n., manae sp.n., falcifer Erséus & Baker, 1982, renaudae sp.n., extrmus (Erséus 1979) comb.n., mexicanus Erséus & Haker, 1982, and bulbosus Erséus, 1979. Olavius sp.n. is established to accommodate the species geniculatus (Erséus, 1981) comb.n., imperfectus sp.n., filithecatus (Erséus. 1981) comb.n. albidus (Jamieson, 1977) comb.n., propinquus sp.n., comorensis (Erséus. 1981) comb.n., cornuatus Davis, 1984, pellucidus sp.n., tenuissimus (Erséus, 1979) macer sp.n., caudatus (Erséus. 1979) comb.n., planus (Erséus, 1979) comb.n., clavatus (Erséus. 1981) comb.n., tantulus sp.n., longissimus (Giere, 1979) comb.n., alius sp.n., avisceralis (Erséus, 1981) comb.n., loisae sp.n., and hanssoni sp.n., Two subgenera are erected for tantulus—longissimus–alius (nominate subgenus Olavius) and avisceralis-loisae-hanssoni (Coralliodriloides subgen.n.), respectively. A tentative phylogeny of the gutless group, which appears monophyletic, is inferred on the basis of a partly computerized Wagner-tree analysis of all 38 species. According to this analysis. According to this analysis, Inanidrilus can be defined by one synapomorphy, more or less sickle-shaped penial setae, whereas Olavius can be discriminated by two such characters, (1) atrium comma-shaped/horizontal rather than erect and (2) copulatory sacs present.
