B). He interpreted the body as 9-segmented but it is not clear from his illustration which body regions his “segments” relate to. The abdomen was described as having two dilated somites anteriorly, followed by four narrower ones, the last one being the genital somite presenting a “...central genital aperture”. This study revealed that the postcephalosomic trunk probably consists of four thoracic prosomites and an undivided urosome. M’Intosh identified only one pair of appendages which he equated with the antennae (or antennules) with which the copepod attaches itself to the host. From their posterior position in his habitus drawing it appears that in reality he was referring to the maxillipeds. The central projection on the anterior ventral margin referred to as the rostrum by M’Intosh (1885) is here reinterpreted as the prominent labrum.

is unusual in the morphology and arrangement of its cephalosomic appendages. The paragnaths, mandibles, maxillules and maxillae are entirely absent while the strongly reduced antennules and antennae are contained within shared anterior sockets on the ventral surface of the cephalosome. Attachment to its maldanid host is secured by the maxillipeds, at least in females, and both the antennules and labral hooks probably function as auxiliary attachment organs. The distal apex of the maxilliped is blunt and modified into a distinct spinular pad as in other annelidicolous families such as the
