Type locality. Between Bird Islet and South Island, Lizard Island, Queensland, Australia (14° 42'S 145° 28'E) GoogleMaps .

Description. Based on male, 5.5 mm, AM P71068.

Head. Head, anteroventral corner rounded, anteroventral slit absent. Eye ovate. Antenna 1 peduncular article 2 shorter than article 1, article 3 minute; accessory flagellum with 3 articles. Antenna 2 gland cone surpassing end of peduncle article 3, article 4 longer than article 5. Upper lip thickened. Mandible palp article 1 nearly 3 x as long as wide, distally triangularly lengthened but not pointed; article three subequal with or somewhat longer than article 2.

Pereon. Gnathopod 1 coxa anteroventral corner produced, acute; merus without sharp posterodistal prolongation; carpus anterior margin rounded. Gnathopod 2 significantly enlarged in both sexes, symmetrical; merus without sharp posteroventral prolongation; propodus palm with well defined palmar corner (about 90°), with two shallow excavations and strong robust setae. Pereopods 5–7 basis with short robust setae on anterior margin; dactylus simple. Per eopod 7 basis posterodistal corner rounded, lengthened and widened into lobe; merus swollen and lengthened posterodistally; all articles except ischium with bundles of long, fine setae.

Pleon. Epimera 1–3 posterodistally not acutely lengthened, no upturned spine; posterior and ventral margins smooth. Uropod 3 rami unequal, dorsoventrally flattened, longer ramus about 1.5 to 2 x length of peduncle, distally subacute, tapering; with apical robust and long fine setae, about 3/4 length of ramus; outer ramus with 1 article. Telson deeply cleft, trapezium-shaped, lobes distally excavated twice, the outer corner of excavations being the longer; inner and outer margins of lobes lacking setae, but long ones (approximately telson length) inserted in excavations.

Female (sexually dimorphic characters). Based on female, 5.0 mm, AM P70602 Gnathopod 2 palm poorly defined, rounded. Telson apically less excavated.

Habitat. Coral rubble or bommies, 2–22 m depth.

Remarks. The dorsoventrally flattened rami of uropod 3 in the species are characteristic.

Distribution. Australia. Queensland: Lizard Island ( Berents 1983 and current study).
