Cucullanus mycteropercae n. sp. is described from the intestine of the black grouper, Mycteroperca bonaci Poey, from the northern coast of Yucatán, México. The new species is readily distinguishable from other Cucullanus species because it possesses an ellipsoidal papilla-like structure situated medially on the anterior cloacal lip of males. Other differentiating characters include the variable position of postcloacal pair 8 in males, the subventral position of phasmids, a slightly ventrally hooked posterior end of gubernaculum, and the presence of a large, cylindroconical sclerotized tail end in both sexes. This is the fourth record of a marine cucullanid off the Yucatán Peninsula in México belonging to Cucullanus Müller, 1777.
墨西哥湾石斑鱼新种(Cucullanus mycteropercae n. sp.)是从墨西哥尤卡坦半岛北部海岸的黑石斑鱼(Mycteroperca bonaci Poey)的肠道中描述出来的。该新物种很容易与其他墨西哥湾石斑鱼物种区分开来,因为它在雄性泄殖腔前唇内侧有一个椭圆形乳头状结构。其他鉴别特征包括雄性泄殖腔后对8的位置可变、尾感器位于腹侧、生殖腔后端略向腹侧钩曲,以及两性均有一个大的圆柱形硬化尾端。这是墨西哥尤卡坦半岛海域属于1777年米勒所定墨西哥湾石斑鱼属的海洋线虫的第四次记录。
