A survey of the parasite fauna of freshwater fishes from the Wet Tropics Bioregion in Queensland, Australia, revealed the presence of a new species of Stemmatostoma Cribb, 1986 (Digenea: Cryptogonimidae). Stemmatostoma cribbi n. sp. is described from the intestine and pyloric caeca of 2 species of grunter (Terapontidae), Hephaestus fuliginosus (Macleay) and Hephaestus tulliensis (De Vis), and the Jungle perch (Kuhliidae), Kuhlia rupestris (Lacepède), collected from the Barron and Mulgrave-Russell River drainage divisions in tropical north Queensland, Australia. Stemmatostoma cribbi is primarily distinguished morphologically from the type and only other species in the genus, Stemmatostoma pearsoni Cribb, 1986, in having consistently fewer oral spines (14 in S. cribbi vs. 16 in S. pearsoni). Alignment of novel molecular data for S. cribbi and S. pearsoni revealed that they differ genetically by 26 nucleotides (2.1%) over the 1,258 bp partial large subunit (LSU) region, 1 nucleotide (0.8%) over the 121 bp partial 5.8S region, and 23 nucleotides (7.2%) over the entire 318 bp ITS2 rDNA region. Bayesian inference and maximum likelihood phylogenetic analyses of the partial LSU region for the species of Stemmatostoma sequenced here were used to explore the relationships of these species to other cryptogonimid species reported from freshwater ecosystems.

乳杆菌 sp。（Digenea：Cryptogonimidae）来自澳大利亚昆士兰湿热带地区的淡水鱼类。

对澳大利亚昆士兰湿热带生物区淡水鱼的寄生虫动物区系进行的一项调查显示，1986年存在一种新的肉食动物克里布（Digenea：Cryptogonimidae）。乳杆菌 sp。从两个物种的肠和幽门盲肠中描述，它们是从Barron和-澳大利亚北昆士兰州北部的罗素河排水区。形态特征和形态学上的区别仅在于形态特征，而另一种是梨形隐孢子虫Cribb，1986年，其口腔棘突一直较少（梨形隐孢子虫为14个，而梨形隐孢菌为16个）。比对的新分子数据的链球菌和链球菌。梨糖醇显示，它们在1,258 bp的部分大亚基（LSU）区域内遗传差异26个核苷酸（2.1％），在121 bp的部分5.8S区域内遗传1个核苷酸（0.8％），而在整个序列中存在23个核苷酸（7.2％） 318 bp ITS2 rDNA区域。利用贝叶斯推断和最大似然系统分析了部分LSU区域中的肉芽肿气孔菌种，以探讨这些菌种与淡水生态系统报道的其他隐gon亚种的关系。
