A new cucullanid, Dichelyne bonacii n. sp., is described from the intestine of the grey snapper Lutjanus griseus and the stomach of the black grouper Mycteroperca bonaci off the coast of Yucatán. The absence of a ventral precloacal sucker and the presence of 11 pairs of caudal papillae in males allocate it to the subgenus Dichelyne. It differs from its congeners in body dimensions and by having two almost equal spicules (left 712-950 and right 722-945microm), two intestinal caeca and in the position of the deirids and excretory pore. Apparently, L. griseus acts as definitive host of this species, whereas M. bonaci may be considered as a postcyclic host. This new species represents the first record of a nematode of the subgenus Dichelyne in marine fishes of Mexico.
一种新的旋尾线虫,迪氏旋尾线虫新种(Dichelyne bonacii n. sp.),从尤卡坦海岸的灰笛鲷(Lutjanus griseus)肠道和黑点石斑鱼(Mycteroperca bonaci)胃中被描述。雄性个体无腹前泄殖腔吸盘且有11对尾乳突,这使其归为迪氏旋尾线虫亚属。它在身体尺寸上与同属其他物种不同,具有两根几乎等长的交合刺(左交合刺712 - 950微米,右交合刺722 - 945微米)、两条肠盲囊以及排泄孔和侧器的位置不同。显然,灰笛鲷是该物种的终末宿主,而黑点石斑鱼可能被视为后循环宿主。这个新物种代表了墨西哥海洋鱼类中迪氏旋尾线虫亚属线虫的首次记录。
