Tripaphylus musteli (van Beneden, 1851) (Copepoda, Siphonostomatoida, Sphyriidae) is redescribed from an adult female collected from the branchial chamber of a starry smooth-hound, Mustelus asterias Cloquet (Carcharhiniformes, Triakidae), captured in the English Channel off Portland, UK. The new account of T. musteli is the first based on a complete adult female and highlighted the lack of a robust distinction separating Tripaphylus Richiardi, in Anonymous, 1878 and Paeon Wilson, 1919 prompting us to relegate Paeon to a junior subjective synonym of Tripaphylus. In the light of this synonymy the eight former species of Paeon are transferred to Tripaphylus as follows: T. ferox (Wilson, 1919) new combination, T. elongatus (Wilson, 1932) new combination, T. vassierei (Delamare Deboutteville & Nuñes-Ruivo, 1954) new combination, T. lobatus (Kirtisinghe, 1964) new combination, T. asymboli (Turner, Kyne & Bennett, 2003) new combination, T. versicolor (Wilson, 1919) new combination, T. australis (Kabata, 1993) new combination, and T. triakis (Castro Romero, 2001) new combination. Comparisons between terminology used in this report and that in the literature indicate that all transformed adult females of Tripaphylus probably possess a full complement of cephalic appendages and maxillipeds. All limbs, with the exception of the maxillae share a general morphological similarity to the corresponding appendages of conspecific males. The maxilla of the transformed adult female of Tripaphylus is a small digitiform protuberance associated with a swelling in some species.
鼬形三盾水蚤(Tripaphylus musteli)(范·贝内登,1851年)(桡足纲,管口水蚤目,剑蚤科),是根据从一只星鲨(Mustelus asterias Cloquet)(真鲨目,皱唇鲨科)的鳃腔中采集到的一只成年雌性个体重新描述的,该星鲨在英国波特兰附近的英吉利海峡捕获。对鼬形三盾水蚤的新描述是基于完整成年雌性个体的首次描述,并突出表明,在区分1878年无名氏记述的里氏三盾水蚤(Tripaphylus Richiardi)和1919年威尔逊记述的芍药水蚤(Paeon Wilson)方面,缺乏有力的区分依据,这促使我们将芍药水蚤归为三盾水蚤的次主观同物异名。鉴于这种同物异名关系,芍药水蚤属原来的8个物种被转移到三盾水蚤属,如下所示:凶猛三盾水蚤(T. ferox)(威尔逊,1919年)新组合,细长三盾水蚤(T. elongatus)(威尔逊,1932年)新组合,瓦氏三盾水蚤(T. vassierei)(德拉马雷·德布特维尔和努涅斯 - 鲁伊沃,1954年)新组合,叶状三盾水蚤(T. lobatus)(基尔蒂辛格,1964年)新组合,无征三盾水蚤(T. asymboli)(特纳、凯恩和贝内特,2003年)新组合,杂色三盾水蚤(T. versicolor)(威尔逊,1919年)新组合,澳洲三盾水蚤(T. australis)(卡巴塔,1993年)新组合,以及三角三盾水蚤(T. triakis)(卡斯特罗·罗梅罗,2001年)新组合。本报告中使用的术语与文献中术语的比较表明,三盾水蚤所有变态后的成年雌性个体可能都拥有完整的头部附肢和颚足。除了上颌骨外,所有附肢在形态上与同种雄性个体的相应附肢总体相似。三盾水蚤变态后的成年雌性个体的上颌骨是一个小的指状突起,在某些物种中与一个肿胀部位相关联。
