根据在印度尼西亚东部马鲁古群岛安汶海域采集的一个标本，描述了一个新的猫鲨属和种。Akheilos suwartanai属于Schroederichthyinae亚科，与其他猫鲨的不同之处在于：背鳍大小相似，眶上嵴存在，假虹吸存在于扣钩上，眼睛下有宽的眼下嵴，后鼻瓣存在，喙软骨融合成喙节。这是该亚科在美洲以外的第一个记录。Akheilos与Schroederichthys亚科的其他属不同之处在于：背侧不融合的扣钩沟，尾鳍腹侧叶，更多的肠瓣转折，臀鳍略大于第二背鳍，以及颜色图案。
A new genus and species of catshark is described based on a single specimen collected off Ambon in the Maluku Islands of eastern Indonesia. Akheilos suwartanai belongs to the subfamily Schroederichthyinae which differs from the other catsharks in a combination of: similar sized dorsal fins, supraorbital crests present, pseudosiphon present on claspers, broad subocular ridges under eyes, posterior nasal flaps present, tips of rostral cartilage fused into a rostral node. It represents the first record of this subfamily outside of the Americas. Akheilos differs from the other genus in the subfamily, Schroederichthys in a combination of: clasper groove not fused dorsally, ventral lobe of caudal fin produced, more intestinal valve turns, anal fin slightly larger than second dorsal fin, and in colour pattern.
