Twenty-nine dactylogyrid species were reported from teleosts collected during a survey of the parasites of fishes of Moreton Bay, Queensland, Australia, in 2016. Two new genera,Ecnomotreman. gen. andPleuronectitreman. gen., were proposed, and 13 new species were illustrated and described:Atherinicus difficilisn. sp.,Diversohamulus similisn. sp., andEcnomotrema cetiosumn. sp. fromAtherinomorus vaigiensis;Haliotrema apiculumn. sp. fromPempheris schwenkii;Haliotrema tugulduriformen. sp. fromScarus ghobban;Lethrinitrema australiensen. sp., andLethrinitrema lituusn. sp. fromLethrinus nebulosus;Tetrancistrum siganioidesn. sp. fromSiganus fuscescens;Ligophorus bostrychusn. sp. fromPlaniliza subviridis;Neohaliotrema gemmulan. sp. fromAbudefduf vaigiensis;Neohaliotrema moretonensen. sp. fromAb. vaigiensisandAb. bengalensis; andPleuronectitrema spirulan. sp. fromPseudorhombus arsius(all from Moreton Bay);Pleuronectitrema kuwaitenseKritsky & Sey n. sp. was described from specimens collected fromP. arsiusin Kuwait during 1996. Ten new host records were recorded:Chauhanellus duriensisLim, 1994 andHamatopeduncularia thalassiniBychowsky & Nagibina, 1969 fromPararius proximus;Diplectanotremasp. 1 and sp. 2 from SillagomaculataandGoniistius vestitus, respectively;Diversohamulus tricuspidatusBychowsky & Nagibina, 1969 fromAt. vaigiensis;Hal.cf.dempsteri(Mizelle & Price, 1964) Young, 1968 fromPrionurus microlepidotus;Hal. spiraleYamaguti, 1968 fromUpeneus tragula;Ligophorus kaohsianghsieni(Gussev, 1962) Gussev, 1985 fromPlaniliza subviridis; andNeohaliotrema malayenseLim & Gibson, 2010 fromAb. bengalensisandAb. whitleyi. Twenty-five new faunal records for Moreton Bay were recorded, including the new species listed above andC.duriensis,Diplectanotremasp. 1 and sp. 2,Diversohamulus tricuspidatusBychowsky & Nagibina, 1969,Glyphidohaptor phractophallusKritsky, Galli, & Yang, 2007,Hal.cf.dempsteri,Hal. johnstoniBychowsky & Nagibina, 1970,Hal. spirale, Yamaguti, 1968Hamatopeduncularia thalassiniBychowsky & Nagibina, 1969,Lethrinitrema nebulosumSun, Li, & Yang, 2014,Ligophorus kaohsianghsieni(Gussev, 1962) Gussev, 1985,Ligophorus parvicopulatrixSoo & Lim, 2012, andNeohaliotrema malayenseLim & Gibson, 2010. Three new combinations were proposed:Hal. sparienseRoubal, 1981 asEuryhaliotrema spariense(Roubal, 1981) n. comb.; andHal. arsiosaVenkatanarasaiah, 1984 andHal. youngiVenkatanarasaiah, 1984 asPleuronectitrema arsiosa(Venkatanarasaiah, 1984) n. comb. andPleuronectitrema youngi(Venkatanarasaiah, 1984) n. comb., respectively;Haliotremasp. of Zhang is transferred toPleuronectitremaasPleuronectitremasp.Hal. ctenochaetiYamaguti, 1968 was replaced withHal. asymphylumn. nom. to remove it from homonymy withHal. ctenochaetiYoung, 1968.Pseudohaliotrematoides zancliYamaguti, 1968 was transferred toHaliotremaasHaliotrema hawaiiensen. nom.Hal. zancliYamaguti, 1968 was considered a junior subjective synonym ofHal. dempsteri.
