A taxonomic and morphological account of a collection of Phallodrilinae from coralline sands at Heron Island in Australia's Great Barrier Reef is given. Ten new forms are described: Jamiesoniella athecata gen. et sp.n. Phallodrilus rectisetosus heronensis subsp.n. P. geniculatus sp.n. P. filithecatus sp.n. P. clavatus sp.n. (latter three all devoid of an alimentary canal), Bathydrilus superiovasatus sp.n. Coralliodrilus atriobifidus sp.n. C. oviatriatus sp.n. C. parvigenitalis sp.n. and the gutless C. avisceralis sp.n. Morphological notes are given for Phallodrilus albidus Jamieson, 1977 and Bathydrilus rohdei (Jamieson, 1977). The new meiobenthic genus Jamiesoniella is characterized by having simple atria with only one pair of prostate glands, which are attached to ectal parts of atria, and by lacking spermathecae and penial setae, The genus is probably related to Aktedrilus Knöllner and Bacescuella Hrabě. A gutless species, Phallodrilus comorensis sp.n. is described from the Comoro Islands in the Mozambique Channel (W Indian Ocean).
