Three new species of Aporocotylidae infecting pufferfishes from Bali are described.
The number of aporocotylids known from pufferfishes of the genus Arothron is doubled.
Molecular analysis indicates the presence of a clade of aporocotylids in pufferfishes.
All known aporocotylids in this clade are inferred to be of the genus Psettarium.
This study is part of the first systematic parasitological survey of fishes from Bali.
