Alebion Krøyer, 1863 is one of the genera of the Caligidae Burmeister, 1835 and can easily be distinguished from other genera by the presence of modified exopodal spines on legs 1-3. Currently there are eight recognised species infecting a variety of elasmobranch hosts. Alebion difficile (van Beneden, 1892) is resurrected based on the difference in the structure of the spermatophores on the genital complex of the female but also the difference in the relative lengths of the posterior processes of the genital complex, the lateral processes on the first abdominal somite and the caudal rami. Additionally, the adult male of A. difficile is described and illustrated and notes provided about the morphology of the sub-adult females and males. Other Alebion species and their hosts collected off South Africa are reported and an updated key to the adult females of the species of Alebion is provided.
阿氏鱼虱属（Alebion Krøyer，1863）是1835年布迈斯特（Burmeister）所定的鱼虱科（Caligidae）的属之一，凭借第1至第3对步足上特化的外肢刺很容易与其他属区分开来。目前已确认有8个物种感染多种板鳃亚纲宿主。基于雌体生殖复合体上精荚结构的差异以及生殖复合体后突、第一腹节侧突和尾叉相对长度的差异，复活了艰难阿氏鱼虱（Alebion difficile，范·贝内登，1892）。此外，还描述并图示了艰难阿氏鱼虱的成年雄性，并提供了关于亚成年雌雄性形态的说明。报告了在南非沿海采集到的其他阿氏鱼虱属物种及其宿主，并提供了阿氏鱼虱属成年雌体的最新检索表。
