Aethycteron robisoni n. sp. is described from the sunburst darter, Etheostoma mihileze Mayden (Perciformes: Percidae), in the Arkansas River Drainage of the Ozark Region in the Central Highlands of Arkansas, USA. Aethycteron robisoni morphologically most closely resembles A. caerulei Suriano & Beverley-Burton, 1982, A. moorei (Mizelle, 1940) and A. nigrei Suriano & Beverly-Burton, 1982, by possessing a male copulatory organ with a distinct distal curvature and spiraling sheath. The haptoral sclerites of A. robisoni, with the exception of the hooks, are distinctly larger than those of the other three species. This is the first time a monogenean parasite has been reported from E. mihileze as well as the first time the genus Aethycteron Suriano & Beverley-Burton, 1982 has been reported from Arkansas, USA.
罗氏艾氏吸虫（Aethycteron robisoni）新物种是从美国阿肯色州中部高地奥扎克地区阿肯色河排水区的太阳爆纹镖鲈（Etheostoma mihileze Mayden，鲈形目：鲈科）中描述出来的。罗氏艾氏吸虫在形态上与1982年的苏氏艾氏吸虫（A. caerulei Suriano & Beverley-Burton）、1940年的穆氏艾氏吸虫（A. moorei，Mizelle）以及1982年的黑色艾氏吸虫（A. nigrei Suriano & Beverley-Burton）最为相似，其雄性交配器官具有明显的远端弯曲和螺旋状鞘。除钩外，罗氏艾氏吸虫的触器硬体明显大于其他三个物种。这是首次报道米氏镖鲈身上的单殖吸虫寄生虫，也是首次报道1982年的艾氏吸虫属（Aethycteron Suriano & Beverley-Burton）来自美国阿肯色州。
