Cymothoa hermani Hadfield, Bruce & Smit, 2011: 57 –68.

Remarks. Cymothoa hermani can be identified by the unique bulbous ornamentation on pereonite 1, anterolateral angles on pereonite 1 rounded and produced past frontal margin of cephalon, long and slender dactyli and the numerous lobes on pleopods 4 and 5 in the ovigerous female.

The only other Cymothoa species known from the region, C. eremita , differs from C. hermani by the lack of the characteristic bulbous ornamentation on pereonite 1 that is present in C. hermani . Cymothoa eremita also has a dorsally visible and wider cephalon with the anterolateral margin of pereonite 1 not produced past the cephalon; irregular posterior margins of the pleonites with pleonite 5 appearing to have very distinctly produced sub-medial points; and more acutely produced lateral pereonite margins than in C. hermani .

Hosts. Only known from Leptoscarus vaigiensis (Quoy & Gaimard, 1824) (see Hadfield et al. 2011). Distribution. Known from the type location, off Miwi Island, Zanzibar, Tanzania (Hadfield et al. 2011).
