Probably most closely related to I. voltae from West Africa, from which it can be easily distinguished by the finely serrated inner side of the pectoral spine (Ref. 43912).Coloration: Preserved specimens: sides pale with few indistinct fine lateral stripes; head and back somewhat darker; in smaller specimens lateral stripes (one above and one below lateral line, one just above base of anal fin) somewhat more distinct; anal fin faintly speckled, other fins colourless (Ref. 43912).
