Pearsonellum pygmaeus n. sp. is described from Cromileptes altivelis (Serranidae), the Barramundi Cod, from Heron Island (southern Great Barrier Reef) and Lizard Island (northern Great Barrier Reef). This new species differs from Pearsonellum corventum (type and only species) in the combination of smaller overall body size, the relative distance of the brain from the anterior end, the relative lengths of both the oesophagus and the testis, the degree to which the testis extends outside the intercaecal field, the shape of the testis, the shape and size of the ovary and the extent to which the uterus loops around the ovary. There are in addition, 20 base pair differences between the ITS2 rDNA sequence of P. pygmaeus n. sp. and that of P. corventum. Three new host records for P. corventum are reported. Adelomyllos teenae n. g., n. sp. is described from Epinephelus coioides (Serranidae), the Estuary Cod, from Moreton Bay, southeast Queensland. The new genus differs from the 22 other sanguinicolid genera in the combined possession of two testes, a cirrus-sac, separate genital pores, a post-ovarian uterus and an H-shaped intestine. A. teenae n. sp. is the third sanguinicolid described from the Epinephelinae. Sanguinicolids have now been reported from 11 species of Serranidae.
新种侏儒派氏吸虫（Pearsonellum pygmaeus n. sp.）是从位于大堡礁南部的赫伦岛和大堡礁北部的蜥蜴岛的波纹唇鱼（波纹唇鱼科）中发现并描述的。这个新物种与派氏吸虫属中的角状派氏吸虫（Pearsonellum corventum，该属的模式种及唯一物种）的区别在于其整体体型较小、脑与前端的相对距离、食管和睾丸的相对长度、睾丸延伸至盲肠间区域之外的程度、睾丸的形状、卵巢的形状和大小以及子宫环绕卵巢的程度。此外，侏儒派氏吸虫新种的ITS2 rDNA序列与角状派氏吸虫的序列之间存在20个碱基对的差异。报告了角状派氏吸虫的三个新宿主记录。新属新种蒂娜阿德洛吸虫（Adelomyllos teenae n. g., n. sp.）是从昆士兰州东南部莫顿湾的尖吻鲈（尖吻鲈科）中发现并描述的。这个新属与其他22个血居吸虫属的区别在于它同时具有两个睾丸、一个阴茎囊、独立的生殖孔、卵巢后的子宫和H形肠道。蒂娜阿德洛吸虫新种是从石斑鱼亚科中描述的第三种血居吸虫。目前已报道11种石斑鱼科鱼类感染血居吸虫。
