Based on ‘D’ female, 5.8 mm, AM P76795. <i>Gnathopod 1</i> subequal in size to gnathopod 2. <i>Gnathopod 2</i> propodus not produced into an anterodistally setose lobe; palm sinusoidal, with posterodistal corner, subquadrate, with 1 robust seta defining palm. <b>Habitat.</b> Living on macroalgae. <b>Remarks.</b> <i>Ampithoe kava</i> with its long (length 3 x breadth) posterodistal blunt tooth on the propodus of gnathopod 2 (in males) is readily distinguished from all other GBR species. The GBR material differs slightly from the material figured from Port Jackson, New South Wales, Australia which has the gnathopod 1 palmar tooth abutting and overlapping the propodus, however this has since been found to be an artefact (A.G.B. Poore, pers. comm.). Material from both Port Jackson and the GBR most commonly have a slight gap between the propodus and the posterodistal tooth, as figured in the original description. <b>Distribution.</b> <i>Australia</i>. Queensland: east of Carter and Yonge reefs, Great Barrier Reef (current study). New South Wales: Coffs Harbour (Peart 2007b); Port Jackson (Poore &amp; Lowry 1997, Peart 2007b). <i>Fiji</i>. Viti Levu (Myers 1985). <i>Hawaii</i> (J.L. Barnard 1970). <i>Mauritius</i> (Appadoo &amp; Myers 2004). <i>Red Sea</i> (Lyons &amp; Myers 1990). <i>Tonga</i> (Myers 1986).
