Cystacanths of Corynosoma pseudohamanni Zdzitowiecki, 1984 (Palaeacanthocephala: Polymorphidae) are redescribed on the basis of specimens recovered from three species of Antarctic notothenioid fish, Trematomus bernacchii Boulenger, Gobionotothen gibberifrons (Lönnberg) and Notothenia coriiceps Richardson, collected from the Prince Gustav Channel, Antarctica. The cystacanths' morphometry and their internal anatomy including trunk muscles were studied using light and scanning electron microscopy (SEM). The characteristic features of this species such as the length of proboscis and the number of hooks (i.e. 260 hooks arranged in 20 rows with 13 hooks each, including two basal hooks) were confirmed and the intraspecific variability was evaluated. Sexual dimorphism was manifested in the shape of the hindtrunk, and the distribution and extent of the somatic armature only. SEM observations of internal anatomy revealed the detailed organization of trunk musculature.
基于从南极古斯塔夫王子海峡采集的三种南极南极鱼科鱼类（伯氏南极鱼、裸眼南极鱼和科氏南极鱼）中回收的标本，对1984年描述的假哈曼柯里诺棘头虫（古棘头虫纲：多形科）的囊棘进行了重新描述。使用光学显微镜和扫描电子显微镜（SEM）研究了囊棘的形态测量及其内部解剖结构，包括躯干肌肉。确认了该物种的特征，如吻的长度和钩的数量（即260个钩，排成20排，每排13个钩，包括两个基部钩），并评估了种内变异性。两性异形仅表现在后躯干的形状以及体表棘的分布和范围上。内部解剖结构的扫描电子显微镜观察揭示了躯干肌肉组织的详细结构。
