Material examined. 1 male (2 slides), AM P77730 (JDT / LIZ 3); 2 adults, AM P77728 (JDT / OPH 2); 1 adult (slide), AM P77729 (JDT / OPH 2); 3 males, 1 female, AM P77732 (QLD 1622); 1 female, AM P70859 (QLD 1689); 1 male, AM P71204 (QLD 1736); 1 juvenile, 1 female (slide), AM P77731 (SEL /LZI-4-1).

Type locality. Kiribati (1°40'S 179°22'W).

Description. Based on male, 5.0 mm, AM P77731.

Head. Head lateral cephalic lobe rounded, anteroventral slit absent, anteroventral corner acute. Eye rounded. Antenna 1 peduncular article 2 longer than article 1; accessory flagellum with 6 articles. Antenna 2 peduncular article 2 gland cone reaching or surpassing end of article 3, article 4 longer article 5. Upper lip thickened. Mandible palp article 1 distally oblique, distal prolongation absent, article 3 shorter than article 2.

Pereon. Gnathopod 1 coxa rhomboidal, anterodistal corner acute, but not lengthened; carpus with notch on anterodistal margin; propodus rounded. Gnathopod 2, propodus rectangular with somewhat rounded anterior margin, palm defined by short acute spine, with 1 shallow semicircular medial excavation opposite to a triangular hump on the dactylus; dactylus with no or one seta on anterior margin, posterior margin with 1–2 triangular humps near palmar excavation. Pereopods 3–7 dactylus bifid. Pereopods 5–7 basis with serrated posterior margin.

Pleon. Epimera 1–2 posterodistal corner with a small spine, Epimeron 3 posterior margin regularly serrated. Uropod 3 rami subequal, distally truncate, with about 4 robust setae that are about half as long as rami. Telson deeply cleft, distally and submarginally incised, with one long and one short robust seta in deeper distal incision and one long seta in marginal incision.

Female (sexually dimorphic characters). Based on female, 3.5 mm, AM P77731. Gnathopod 2 dactylus with triangular hump(s) on inner side of dactylus and with smaller medial palmar excavation than that of male.

Habitat. Coral rubble, sand, coralline algae, creek lined with mangroves. 1–9 m depth.

Remarks. The triangular hump on the inner side of the gnathopod 2 dactylus, which is drawn by Schellenberg (1938) for the male of Quadrimaera pacifica, is only well developed in this species.

Distribution. Australia. Queensland. Lizard Island (Berents 1983, current study). Red Sea (Ruffo 1969). Madagascar (Ledoyer 1967, 1983). South Africa (Griffiths 1973). India (Sivaprakasam 1966). Mauritius (Appadoo et al. 2002). Marshall Islands and Kiribati (Schellenberg 1938, J.L. Barnard 1965). Fiji (Schellenberg 1938, Myers 1985). Hawaii (Schellenberg 1938, J.L. Barnard 1970).
