Abstract

We describe 2 new species of Affecauda from the intestine of acanthuroid fishes of the Indo-West Pacific.  Affecauda rugosa n. sp. is described from 1 mature specimen in excellent condition and 1 immature fractured specimen from the intestine of the sailfin tang, Zebrasoma veliferum (Acanthuridae), from Noumea, New Caledonia.  Affecauda salacia n. sp. is described from the intestine of the ocellated spinefoot, Siganus corallinus (Siganidae), from Lizard Island, Great Barrier Reef, Queensland, Australia.  Each of these species is made distinct from the type-species, Affecauda annulata Hall & Chambers, 1999, by combinations of the extent of tegumental annulations, conformation of the oesophagus and position of the ovary.  The description of 2 new species of Affecauda necessitates a revision of the generic diagnosis, which is here amended to incorporate the additional species.  A key to species is provided.  The description of further species of Affecauda from waters external to the Great Barrier Reef and from siganid fishes expands the biogeographical range for species of Affecauda, from species of Naso on the Great Barrier Reef, to acanthuroid fishes of the western Pacific.
