Phylogenetic analysis based on ribosomal DNA markers indicates that there is a discrete clade of species of Transversotrema Witenberg, 1944 associated with mullid fishes of the Indo-West Pacific, although there is only one previous record of transversotrematids from these fishes. Each of the species in this clade bears broad morphological similarity to previous concepts of either Transversotrema haasi Witenberg, 1944 or Transversotrema licinum Manter, 1970, yet none of them is attributed here to either of these species. Four new species of Transversotrema are described from mullid fishes of the tropical and sub-tropical Indo-West Pacific using a combination of morphology, morphometric analysis and DNA sequencing. Transversotrema cabrarum n. sp. is described from Parupeneus spilurus (Bleeker) from Ningaloo Reef (Australia), and recorded from Parupeneus cyclostomus (Lacepède), Parupeneus pleurostigma (Bennett) and Parupeneus trifasciatus (Lacepède) from the same location. Transversotrema chevrarum n. sp. is described from Lizard Island (Great Barrier Reef, Australia) from Parupeneus ciliatus (Lacepède), and further recorded from Parupeneus barberinus (Lacepède), P. cyclostomus, Parupeneus indicus (Shaw), Parupeneus multifasciatus (Quoy & Gaimard) and P. trifasciatus at the same location. Transversotrema cutmorei n. sp. is described from Upeneus tragula Richardson from Moreton Bay, Australia. Transversotrema tragorum n. sp. is described from Parupeneus indicus from Lizard Island and recorded from P. barberinus, P. ciliatus P. cyclostomus, P. multifasciatus and P. trifasciatus from the same location. An additional species, also from mullids from Lizard Island, is delineated on the basis of molecular data, but not formally described. Like many other transversotrematids, the species described here appear to have limited geographical distributions.
