Buckarootrema goodmani n. g., n. sp. is described from the small intestine of the Murray turtle, Emydura macquarii (Gray, 1830), from the vicinity of Warwick, Queensland, Australia. The distinctive taxonomic features include the vitellarium, which consists of 2 compact masses directly anterior to and occasionally overlapping the testes; the uterus with extensive pre- and postovarian coils; intestinal ceca with small, medial diverticula that terminate anterior to or at the anterior margin of the testes; a comma-shaped cirrus sac with both internal and external seminal vesicles. Phylogenetic systematic analysis of the genera of the Pronocephalidae including Buckarootrema and Notopronocephalus, the only other genus of pronocephalids reported from Australian freshwater turtles, indicates that Buckarootrema is the sister taxon of Neopronocephalus and Notopronocephalus is the sister group of the rest of the Pronocephalinae.
巴克罗吸虫属新属新种巴克罗古德曼吸虫(Buckarootrema goodmani)是在澳大利亚昆士兰州沃里克附近的默里河龟(Emydura macquarii,格雷,1830年)的小肠中发现并描述的。其独特的分类特征包括:卵黄腺由紧挨着睾丸前方的两个紧密团块组成,偶尔与睾丸重叠;子宫有广泛的卵巢前和卵巢后盘绕;肠盲囊有小的内侧憩室,在睾丸前方或睾丸前缘处终止;有一个带内、外贮精囊的逗号形阴茎囊。对包括巴克罗吸虫属和诺托原头吸虫属(Notopronocephalus)在内的原头科各属进行系统发育分析,诺托原头吸虫属是另一个从澳大利亚淡水龟中报道的原头科属,结果表明巴克罗吸虫属是新原头吸虫属(Neopronocephalus)的姐妹分类单元,而诺托原头吸虫属是原头亚科其他类群的姐妹类群。
