A new species of stomach fluke, Dinurus ivanosi (sp. nov.), was recovered from the dolphin fish, Coryphaena hippurus, off the Kerala Coast, India. It is similar to other Dinurus species in the plicated prosoma, trilobed seminal vesicle and seven vitellaria, but differs from them in the length of the pharynx, unequal lobes of the seminal vesicle and unequal size of the testes. The most important diagnostic features of the new species are the general shape and proportions of the body, the position of the oral sucker, elongated pharynx, small distal lobe of the seminal vesicle, and larger anterior testis, smaller egg size, short and slender vitellaria and the limited extent of the vitelline field.
在印度喀拉拉邦海岸外的鲯鳅（Coryphaena hippurus）体内发现了一种新的胃吸虫——伊万诺西迪努吸虫（Dinurus ivanosi，新物种）。它在具褶皱的前体、三叶精囊和七个卵黄腺方面与其他迪努吸虫物种相似，但在咽的长度、精囊叶大小不等以及睾丸大小不等方面与它们不同。新物种最重要的诊断特征是身体的总体形状和比例、口吸盘的位置、细长的咽、精囊远端小叶、较大的前睾丸、较小的卵大小、短而细的卵黄腺以及卵黄腺分布范围有限。
