Khawia saurogobii n. sp. is described from the intestine of the cyprinid fishes Saurogobio dabryi and Saurogobio dumerili in China. The new species belongs to the Lytocestidae and is placed in Khawia because of its afossate scolex, vitelline follicles in the cortical parenchyma, uterus not looping anterior to the cirrus sac, gonopores separate but close together in distinct genital atrium, external seminal vesicle absent, and postovarian follicles present. The new species differs from other congeneric species by the shape of the body markedly tapering posteriorly from the end of the anterior third, the shape of the scolex that is very short and markedly wider than the neck, spatulate without incisions, but shallow superficial grooves, vitelline follicles and testes starting immediately posterior to the scolex, and an ovary with long, posterior arms bent medially, thus giving the shape of an inverted A.
新种苏氏卡维绦虫(Khawia saurogobii n. sp.)是在中国的鲤科鱼类达氏蛇鮈(Saurogobio dabryi)和杜氏蛇鮈(Saurogobio dumerili)的肠道中发现并描述的。该新种属于裸头绦虫科(Lytocestidae),因其无槽头节、皮层实质中有卵黄滤泡、子宫在阴茎囊前方不盘绕、生殖孔分开但在明显的生殖腔内靠得很近、无外贮精囊以及有卵巢后滤泡而被归入卡维绦虫属(Khawia)。该新种与其他同属物种的区别在于:虫体形状从身体前三分之一末端向后显著变细;头节形状非常短且明显比颈部宽,呈匙形无切口但有浅的表面沟;卵黄滤泡和睾丸在头节后立即开始;卵巢有长的后臂且向内弯曲,呈倒“A”形。
