Species of Rhadinorhynchus, collected from Australian waters were examined. Specimens of Rhadinorhynchus from Scorpis aequipinnis, Girella tricuspidata, Johnius australis and Grammatobothus polyophthalmus could not be identified further. New host and locality records are reported for R. bicircumspinus found in Trachurus declivis and Rexea solandri from the east coast of Tasmania; R. carangis found in Trachinotus bailonii and T. copperingi from Queensland and Western Australian coasts; R. polynemi from Queensland; R. seriolae found in Seriola lalandi from the east coast of Australia. An immature female specimen of R. johnstoni provided no additional data on the species. Rhadinorhynchus biformis sp. nov., described from Pelates quadrilineatus and a trumpeter from Moreton Bay, Queensland differs from all its congeners in the pattern of the trunk spines, a single field of numerous small spines ventro-laterally, overlapping with irregular rows and circles of larger spines extending posteriorly. Rhadinorhynchus pichelinae sp. nov. described from Upeneichthys vlamingi from Point Peron, Western Australia differs from all its congeners in having proboscis armature of 10 longitudinal rows of 24-28, usually 26-27 hooks up to 87 long and a single field of 21-24 irregular circles of spines on the anterior trunk, with the posterior circles incomplete dorsally. Rhadinorhynchus polydactyli sp. nov. described from Polydactylus sp. from Moreton Bay is differentiated from all congenerics by the elongated neck of the females and having a proboscis armature of up to 34 hooks in 10 longitudinal rows. Rhadinorhynchus pomatomi sp. nov. found in Pomotomus saltrix differs from its most similar congeners, those without dorsal trunk spines, in having a proboscis armature of 12-15 rows of 20-22 hooks up to 73.5-80.5 long. Rhadinorhynchus bicircumspinus, R. biformis, R. pichelinae, R. polydactyli and R. pomatomi are known only from Australian waters while R. carangis and R. seriolae are also known from Japanese waters, R. johnstoni from the western Pacific and R. polynemi from the Indian coast.
对采自澳大利亚海域的柔棘吻虫属物种进行了检查。无法进一步鉴定采自等鳍蝎鱼、三尖姬鲷、澳洲若鲹和多眼斑鲬的柔棘吻虫标本。报告了在塔斯马尼亚东海岸的斜竹荚鱼和索氏雷氏鱼中发现的双环柔棘吻虫的新宿主和新地点记录；在昆士兰和西澳大利亚海岸的巴伊洛笛鲷和铜色笛鲷中发现的笛鲷柔棘吻虫；来自昆士兰的多线柔棘吻虫；在澳大利亚东海岸的黄条鰤中发现的黄条鰤柔棘吻虫。约翰斯顿柔棘吻虫的一个未成熟雌性标本未提供该物种的更多数据。新描述的双形柔棘吻虫，采自昆士兰摩顿湾的四线叶鲷和一种喇叭鱼，其躯干棘的模式与所有同属物种不同，腹侧有单个区域的许多小棘，与向后延伸的不规则大棘行和棘圈重叠。新描述的皮氏柔棘吻虫，采自西澳大利亚佩伦角的弗氏副绯鲤，其吻部具10纵排24 - 28个、通常26 - 27个长达87的钩，前躯干有单个区域的21 - 24个不规则棘圈，后圈在背侧不完整，这使其与所有同属物种不同。新描述的多指柔棘吻虫，采自摩顿湾的多指马鲅，其雌性颈部细长，吻部具多达34个钩，排成10纵排，这使其与所有同属物种不同。在澳洲狐鲣中发现的新种澳洲狐鲣柔棘吻虫，与其最相似的无背躯干棘的同属物种不同，其吻部具12 - 15排20 - 22个长达73.5 - 80.5的钩。双环柔棘吻虫、双形柔棘吻虫、皮氏柔棘吻虫、多指柔棘吻虫和澳洲狐鲣柔棘吻虫仅见于澳大利亚海域，而笛鲷柔棘吻虫和黄条鰤柔棘吻虫也见于日本海域，约翰斯顿柔棘吻虫见于西太平洋，多线柔棘吻虫见于印度海岸。
