Robinia aurata n. g., n. sp. is described from Liza aurata (Mugilidae), the golden grey mullet, from the Ebro Delta, Spanish Mediterranean. The new genus differs from all other hemiurid genera in the combined possession of muscular flanges and a vestigial ecsoma. Within the Bunocotylinae, which currently accommodates 2 genera, Bunocotyle and Saturnius, the new genus exhibits a unique combination of blind caeca, Juel's organ, post-ovarian bulk of the uterus in the hind-body, and tegumental papillae surrounding the oral and ventral sucker apertures. Furthermore, Robinia n. g. differs from both Bunocotyle and Saturnius in the nature of the muscular extensions around the oral sucker, with the shape of a muscular belt in the latter and numerous muscular papillae in the former. The phylogenetic hypothesis for the Bunocotylinae developed from sequence data analyses based on partial lsrDNA and complete ssrDNA combined (22 species) and V4 domain of the ssrRNA gene (37 species) supports the erection of the new genus and confirms its position within the Hemiuroidea. Both molecular analyses confirmed the monophyly of the Hemiuroidea, its division into 2 major clades and the polyphyly of the Derogenidae, as in previous studies, and suggest that the Gonocercinae (with 2 genera, Gonocerca and Hemipera), may require a distinct familial status. Finally, there was poor support for the distinct status of the Lecithasteridae and Hemiuridae, following previous suggestions based on different sequence data sets. A key to genera of the Bunocotylinae is presented.
金花刺槐属（Robinia），新物种，是从西班牙地中海埃布罗三角洲的金色灰鲻（Liza aurata，鲻科）中描述的。这个新属与所有其他半尾科属的区别在于同时拥有肌肉凸缘和退化的外体。在目前包含Bunocotyle和Saturnius两个属的Bunocotylinae亚科中，新属呈现出独特的组合特征，包括盲肠、尤尔氏器官、位于后体子宫卵巢后的部分、以及围绕口吸盘和腹吸盘孔的体表乳头。此外，金花刺槐属在口吸盘周围肌肉延伸的性质上与Bunocotyle和Saturnius都不同，后者的口吸盘周围肌肉延伸呈肌肉带形状，而前者则有许多肌肉乳头。基于部分lsrDNA和完整ssrDNA联合分析（22个物种）以及ssrRNA基因V4结构域（37个物种）的序列数据分析得出的Bunocotylinae亚科系统发育假说支持新属的建立，并确认了其在半尾科中的位置。两项分子分析都证实了半尾科的单系性、其分为两个主要分支以及Derogenidae科的多系性，正如之前的研究一样，并表明Gonocercinae亚科（有Gonocerca和Hemipera两个属）可能需要一个独特的科级地位。最后，根据之前基于不同序列数据集的建议，对Lecithasteridae科和Hemiuridae科的独特地位支持不足。文中给出了Bunocotylinae亚科属的检索表。
