摘要 在深海夏威夷柳珊瑚 (Placogorgia sp.) 标本的皮质瘿内发现了 25 个新的鞘甲酸寄生虫标本，即 Gorgonolaureus muzikae。这些代表了夏威夷已知的第一种抗坏血酸。 G. muzikae 与其同类 G. bikiniensis 的不同之处主要在于其较大的尺寸和设置的细节。描述和说明了五个发育阶段：成熟雌性、年轻雌性、晚期早熟期、早熟期和无节幼体。将protander与Synagoga的物种进行比较，并指定了区分两个属的特征。回顾了 Ascothoracida 的性行为，并重建了 G. muzikae 的生命周期如下：卵和幼虫在成熟雌性的甲壳内孵化；假设有一个双壳、自由游动的雄性阶段；在对一只或多只已确定的雌性进行授精后，它会永久定居在寄主柳珊瑚上；当雄性雄性变成雌性时，背甲瓣膜融合并向背侧扩张，第一和第二...
Summary Twenty-five specimens of a new ascothoracid parasite, Gorgonolaureus muzikae were found within cortical galls on specimens of a bathyal Hawaiian gorgonian, Placogorgia sp. These represent the first ascothoracid known from Hawaii. G. muzikae differs from its congener G. bikiniensis primarily in its larger size and details of setation. Five developmental stages are described and illustrated: the mature female, young female, late protander, protander, and nauplius. The protander is compared to species of Synagoga, and the characters distinguishing the two genera are specified. Sexuality in Ascothoracida is reviewed, and the life cycle of G. muzikae is reconstructed as follows: eggs and larvae are brooded within the carapace of a mature female; a bivalved, free-swimming male stage is postulated; after inseminating one or more established females it settles permanently on a host gorgonian; as the protandric male changes into a female, the carapace valves fuse and expand dorsally, the first and second a...
