Based on female, 3.0 mm, AM P70721. Sternal spines absent. <i>Gnathopod 1</i> carpus a little over one half length of propodus; propodus with palm defined by a right angle and a robust seta. <i>Gnathopod 2</i> basis anterodistal margin without flange; carpus shorter than propodus, with sparse setae; propodus with long setae, less dense that those of male. <b>Habitat.</b> Primarily coral rubble and coarse sand. Occasionally in <i>Halimeda</i>, mixed red and brown algae, tunicates. <b>Remarks.</b> The species resembles <i>G. longispinosus</i> in general appearance but the posterodistal margin of the male gnathopod 1 propodus is rounded in <i>G. ovatus</i> (acute in <i>G. longispinosus</i>). In addition, the uropods 1 and 2 peduncles have very short distoventral spines in <i>G. ovatus</i> whereas they are longer than the peduncle in <i>G. longispinosus</i>. <b>Distribution.</b> <i>Australia</i>. Queensland: Lizard Island (current study). <i>Papua New Guinea</i>. Madang lagoon (Myers 1995). <i>Vanuatu</i>. Efate Island (Myers 1985a). <i>Fiji</i>: Viti Levu (Myers 1985 a, 1985b). <i>Western Samoa</i>. Upolu Island (Myers 1985a). <i>Society Islands</i>. Moorea (Myers 1989).
