Description:

The following six species of the Philometridae (Nematoda: Dracunculoidea) were recorded from marine fishes off the northern coast of Australia in 2015 and 2016: Philometra arafurensis sp. n. and Philometra papillicaudata sp. n. from the ovary and the tissue behind the gills, respectively, of the emperor red snapper Lutjanus sebae (Cuvier); Philometra mawsonae sp. n. and Dentiphilometra malabarici sp. n. from the ovary and the tissue behind the gills, respectively, of the Malabar blood snapper Lutjanus malabaricus (Bloch et Schneider); Philometra sp. from the ovary of the goldbanded jobfish Pristipomoides multidens (Day) (Perciformes: all Lutjanidae); and Digitiphilometroides marinus (Moravec et de Buron, 2009) comb. n. from the body cavity of the cobia Rachycentron canadum (Linnaeus) (Perciformes: Rachycentridae). Digitiphilometroides gen. n. is established based on the presence of unique digital cuticular ornamentations on the female body. New gonad-infecting species, P. arafurensis and P. mawsonae, are characterised mainly by the length of spicules (252-264 µm and 351-435 µm, respectively) and the structure of the gubernaculum, whereas P. papillicaudata is characterised mainly by the body length (70 mm) of gravid female, extent of the oesophageal gland, size of caudal projections and the location in the host. Dentiphilometra malabarici differs from congeners mainly in the arrangement of circumoral teeth (in a single row), extent of the oesophageal gland and the absence of sclerotised teeth or protuberances on the oesophageal lobes in the mouth. Digitiphilometroides marinus has not previously been reported from fishes in Australian waters., František Moravec, Diane P. Barton., and Obsahuje bibliografii
