Material examined. 1 female AM P70975 (QLD 1684) ; 1 female, AM P70831 (QLD 1687) ; 1 male, 1 female, AM P70962 (QLD 1687) .
Type locality. Blue Lagoon , Lizard Island, Queensland, Australia (~ 14°41'S 145°27'E) GoogleMaps .
Description. Based on holotype, male, 2.8 mm, AM P37407 ( Myers, 1988b).
Head. Head lateral cephalic lobes apically truncate. Antenna 1 flagellum with about 16 articles; accessory flagellum multiarticulate. Antenna 2 with few long setae. Lower lip with fine setae and stout setae. Maxilla 1 inner plate with 1 long pectinate apical seta. Mandible, palp article 3 longer than 2, posterior margin weakly falcate, posterior margin with setae of two distinct lengths, long setae and an under-story of shorter regularly spaced setae.
Pereon. Pereonites 2–4 with sternal spines, apically acute on segments 2–3. Gnathopod 1 enlarged in males only; coxa weakly produced anterodistally, sub-acute; basis robust, half or more as broad as long, without a spine, posterodistal margin with two long setae, anterodistal margin with strong flange; ischium anterior margin without flange, posterior margin without setae; merus not greatly elongated, fused along its entire length with carpus, posterior margin without posterodistal spine; carpus one quarter length of propodus, anterior margin with few setae; anterior margin without spine; without an oblique row of long setae on inner face, posterior margin without spines; propodus anterior margin weakly setiferous, posterior margin evenly convex, palm present, delimited from posterior margin, margin forming a broad excavate sinus, palm defined by strong posterodistal spine, with robust seta defining palm, without spine near base of dactylus; dactylus more than half length of propodus, fitting palm. Gnathopod 2 subchelate; basis anterodistal margin without flange, posterodistal margin without robust setae and with few fine setae; merus not enlarged or produced away from carpus; carpus longer than propodus, anterior margin not lobate, anterior margin with short sparse setae; propodus with short dense setae, palm with robust seta defining palm. Pereopod 3 without brush of long setae on merus. Pereopod 6 basis not produced posterodistally. Pereopod 7 significantly less than 125% length of pereopod 6.
Pleon. Epimeron 3 posterodistal margin produced into a small spine. Uropod 1 rami subequal, peduncle much longer than broad, distoventral spine shorter than peduncle. Uropod 2 biramous; peduncle with distoventral spine subequal in length with peduncle. Uropod 3 biramous, rami subequal, inner ramus subequal with length of peduncle. Telson with distal fine setae only.
Female (sexually dimorphic characters). Based on paratype female, 3.0 mm, AM P37408 ( Myers, 1988b). Sternal spines absent. Gnathopod 1 carpus less than two thirds length of propodus; palm with distal shallow excavation, defined by robust seta; dactylus overlapping palm .
Habitat. Rubble, algal turf, Ecklonia radiata holdfasts, Sargassum sp. , Jania .
Remarks. The dorsal pigmentation of this species is unique in the genus.
Distribution. Australia. Queensland: Lizard Island ( Myers 1988b and current study); New South Wales: Broom Heads, Byron Bay, Woolgoolga ( Myers 1988b); Western Australia: Ned’s Camp, Cape Range National Park ( Myers 1988b).
