“…Little attention has been paid to the nasal fossae of Australian elasmobranchs as possible habitats for monogeneans. In April 1987, the opportunity arose to examine a large specimen of the spotted eagle ray, Aetobatus narinari Euphrasen, 1790 from Moreton Bay, Queensland and several monocotylids of two separate species were found in the nasal fossae: these were a previously undescribed species of Empruthotrema Johnston & Tiegs, 1922 and Thaumatocotyle pseudodasybatis Hargis, 1955, which was originally proposed for specimens found on the skin of the same host species in Florida, USA. However, because of the difference in microhabitat, a comparative examination of the Australian specimens of T. pseudodasybatis with those from the United States was made.…”

Empruthotrema kearni n. sp. and Thaumatocotyle pseudodasybatis Hargis, 1955 (Monogenea: Monocotylidae) are reported from the nasal fossae of the spotted eagle ray, Aetobatus narinari Euphrasen, 1790, from Moreton Bay, Queensland, Australia. The discovery of E. kearni n. sp. is the first record of this genus from the Myliobatidae and a new geographical record for the genus. A comparison of T. pseudodasybatis from Florida, USA and from Queensland, Australia revealed morphometrical and microhabitat differences. The discovery of T. pseudodasybatis in Australian waters is a new geographical record for this species.

“…Dendromonocotyle was proposed by Hargis (1955) and placed in its own subfamily, the Dendromonocotylinae, to accommodate a monocotylid species from the skin of Dasyatis say (Dasyatidae) captured in Alligator Harbor, Florida, USA. Ten additional species have since been described from the skin of dasyatid, myliobatid and urolophid rays (Table 1).…”

Abstract. Dendromonocotyle species (Monogenea: Monocotylidae) are the only monocotylids to parasitize the skin of chondrichthyan hosts. Currently 11 species are recorded from the skin of ray species in the Dasyatidae, Myliobatidae and Urolophidae. There have been increasing reports of Dendromonocotyle outbreaks on rays kept in public aquaria. This paper provides a broad review of Dendromonocotyle that should assist taxonomists and aquarists with species identification and help decisions on potential control methods for Dendromonocotyle infections. The taxonomy and host-specificity of Dendromonocotyle are discussed and a key to current species is provided. We summarise what little is known about the biology of Dendromonocotyle including egg embryonation and hatching, feeding, camouflage and reproduction. The efficacy of freshwater baths, chemical treatments and biological control measures such as the use of cleaner fish for Dendromonocotyle is also discussed. We demonstrate that effective control of Dendromonocotyle on captive rays is hampered by the lack of basic biological data on the life cycle of the parasites. A case history is provided outlining the success of a public aquarium (Underwater World, Mooloolaba, Queensland, Australia) in managing D. pipinna infections on captive Taeniura meyeni without chemical intervention simply by taking measures to reduce host stress.Most Monogenea are recorded from the skin, fins and gills of teleost fish and only about 200 valid monogenean species in seven families (Acanthocotylidae, Amphibdellidae, Capsalidae, Hexabothriidae, Loimoidae, Microbothriidae, Monocotylidae) are known from various sites on chondrichthyans (Whittington and Chisholm 2003). In our experience, the infection intensity of monogeneans on wild sharks and rays is generally low. However, when elasmobranchs are kept in captivity, monogenean intensities can increase significantly due to their direct life cycle. In extreme cases, monogeneans can cause lesions at their attachment site which may result in the death of the elasmobranch either indirectly (via secondary infections) or directly (e.g. Poynton et al. 1997, Bullard et al. 2001.The Monocotylidae comprises 23 genera and represents approximately 60% of all monogeneans recorded from elasmobranchs . This is a unique family because members can parasitize a broad diversity of sites on their chondrichthyan hosts including the skin, gills, nasal tissue, urogenital system and inner wall of the body cavity. Members of Dendromonocotyle are the only monocotylids to parasitize the skin. Recently there have been an increasing number of reports of Dendromonocotyle outbreaks on rays in public aquaria.This review provides information on the taxonomy of Dendromonocotyle and a key to species to assist with identification. We highlight how little is known about the biology of Dendromonocotyle and how this lack of information impacts on the development of effective biological and chemical control measures. We then outline how one public aquarium, Underwater World, in Que...

Compared with that of other charismatic elasmobranchs, the component community of metazoan parasites infecting endangered smalltooth sawfish Pristis pectinata is exceedingly poorly characterized: adults of Dermophthirioides pristidis and Neoheterocotyle inpristi (ectoparasitic flatworms of skin and gill, respectively) were the only confirmed parasites prior to the description, based on specimens reported herein, of Mycteronastes caalusi. Our opportune and directed parasitological examinations of 290 smalltooth sawfish (277 live inspections; 13 necropsies; 671 to 2640 mm stretch total length) in south Florida coastal waters revealed at least 8 species of Platyhelminthes, 9 of Arthropoda, 4 of Annelida, and 1 of Nematoda. This collection includes representatives of an undescribed species of Aporocotylidae (Digenea) and myriad new host records, considerably updating and advancing our understanding of smalltooth sawfish symbionts. We also confirm that D. pristidis and N. inpristi are extant and propose D. pristidis as a reliable biological tag. Some of these parasites are evidently highly host-specific and so vulnerable to extinction.
