Hamaticolax resupinus n. sp. is described from specimens collected from the gill cavities of Coelorinchus mediterraneus Iwamoto & Ungaro and Coryphaenoides mediterraneus (Giglioli) (Gadiformes: Macrouridae) caught in the Western Mediterranean Sea at depths between 1,236 and 1,626 m. Hamaticolax resupinus n. sp. closely resembles H. maleus Oldewage, 1994, but differs from the latter by its smaller body size and in having a genital double-somite in the female that is markedly wider than the free abdominal somites and has strongly convex lateral margins. The new species is only the second bomolochid found on a macrourid host and is the first from depths in excess of 1,200 m. Hamaticolax resupinus n. sp. also represents the first parasitic copepod recorded from Coe. mediterraneus and only the third one from Cor. mediterraneus worldwide.
倒刺哈马鳃虱新种（Hamaticolax resupinus n. sp.）是根据从地中海西部1236至1626米深处捕获的地中海腔吻鳕（Coelorinchus mediterraneus Iwamoto & Ungaro）和地中海深海鳕（Coryphaenoides mediterraneus (Giglioli)）（鳕形目：鼠尾鳕科）鳃腔中采集的标本描述的。倒刺哈马鳃虱新种与1994年的马氏哈马鳃虱（H. maleus Oldewage）非常相似，但与其不同之处在于体型较小，且雌性具有一个生殖双体节，该双体节明显宽于游离的腹部体节，且侧缘强烈凸出。该新物种是在鼠尾鳕科宿主上发现的第二种博氏鳃虱科物种，也是首个来自深度超过1200米处的物种。倒刺哈马鳃虱新种也是首次记录到寄生于地中海腔吻鳕的寄生桡足类，并且是全球范围内仅有的第三种寄生于地中海深海鳕的此类生物。
