Three new species of Rhabdochona Railliet, 1916 are described and illustrated from Salmo gairdneri Richardson (rainbow trout) in freshwater streams in California: Rhabdochona californiemis n. sp., R. paxmani n. sp., and R. satmonis n. sp. Rhabdochona californiensis n. sp. is characterized by 14 anteriorly directed teeth in the prostome, egg devoid of filaments or floats, male and female tail terminus with a single mucro, left (long) spicule slender with a moderate distended podoid terminal end, spicular ratio 1:3.8. Rhabdochona paxmani n. sp. is characterized by 10 teeth in the prostome, eggs with polar floats, left (long) spicule slender with podoid terminus distended and having a minute subterminal spine; right spicule with prominent gorgeret (barb), spicular ratio 1:4.3, male and female tail terminus with a cuticular conical rounded short projection. Rhabdochona salmoni, n. sp. is characterized by 10 teeth anteriorly directed in the prostome, eggs with polar floats, left spicule slender with a distended podoid terminus; right spicule with a sharply indented gorgeret, spicular ratio 1:4.3, male and female tail terminus with a conical or rounded tip.
本文描述并展示了采自加利福尼亚淡水溪流中虹鳟（Salmo gairdneri Richardson）体内的3种新的瑞利线虫（Rhabdochona Railliet，1916）：加利福尼亚瑞利线虫（Rhabdochona californiemis n. sp.）、帕克曼瑞利线虫（R. paxmani n. sp.）和鲑鱼瑞利线虫（R. satmonis n. sp.）。加利福尼亚瑞利线虫的特征为：口前部有14颗向前的齿，虫卵无丝状物或浮器，雄虫和雌虫尾端有单个短刺，左（长）交合刺细长，末端豆形部分适度膨大，交合刺比例为1:3.8。帕克曼瑞利线虫的特征为：口前部有10颗齿，虫卵有极浮器，左（长）交合刺细长，末端豆形部分膨大且有一个微小的亚末端刺；右交合刺有明显的颈环（倒刺），交合刺比例为1:4.3，雄虫和雌虫尾端有一个角质化的圆锥形圆形短突起。鲑鱼瑞利线虫的特征为：口前部有10颗向前的齿，虫卵有极浮器，左交合刺细长，末端豆形部分膨大；右交合刺有明显凹陷的颈环，交合刺比例为1:4.3，雄虫和雌虫尾端有圆锥形或圆形的尖端。
