Material Examined. 1 male, AM P70556 (QLD 1618) ; 1 male, AM P70642 (QLD 1621) ; 1 male, 3 female, 3 juveniles, AM P70711 (QLD 1637) ; 3 males, 9 females, 4 juveniles, AM P71145 (QLD 1707) ; 1 male, 2 females, AM P71077 (QLD 1731) ; 1 male, 1 female, AM P71227 (QLD 1773) ; 1 male, 1 female, AM P71229 (QLD 1773) .

Type locality. Sanur , Bali, Indonesia (~ 8°40'30''S 115°15'40''E) .

Description. Based on male, AM P71145, 4.0 mm.

Head. Head lateral cephalic lobes apically truncated. Antenna 1 flagellum with 20 or less 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 posterior margin straight or weakly falcate, longer than 2, posterior margin with setae of two distinct lengths, long setae and an understory of much shorter regularly spaced setae.

Pereon. Pereonites 2–4, with apically acute sternal spines. Gnathopod 1 enlarged in males only; coxa anterodistally rounded; basis robust, half or more as broad as long, with few or no setae present along margin, with setae sparse or absent, anterodistal margin with flange weak or absent; ischium anterior margin without flange; merus not greatly elongated, fused along its entire length with carpus, posterior margin with setae sparse or absent, without posterodistal spine; carpus one third or less length of propodus, without spines and with setae sparse or absent; propodus anterior margin moderately clothed in short setae, palm delimited from posterior margin and forming a narrow sinus, defined by strong posterodistal spine; dactylus more than half length of propodus, significantly overlapping palm. Gnathopod 2 basis anterior margin concave. anterodistal margin with strong spine, posterodistal margin without robust setae; basis anterior margin weakly setiferous, with few or no long setae; carpus subequal with or shorter than propodus, with short sparse setae; propodus with long sparse setae. Pereopod 3 basis anterior margin strongly expanded, convex. Pereopod 7 significantly greater than 125% length of pereopod 6.

Pleon. Epimeron 3 posterodistal margin with a small notch. Uropod 1 distoventral spine shorter than peduncle. Uropod 2 peduncle with distoventral spine. Uropod 3 biramous, outer ramus more than half length of inner ramus, inner ramus at least twice length of peduncle.

Female (sexually dimorphic characters). Based on female, 4.5 mm, AM P71145. Gnathopod 1 carpus two thirds or less length of propodus; palm defined by rounded or oblique corner. Gnathopod 2 basis anterior margin sub-straight, anterodistal margin without spine.

Habitat. Among algae.

Remarks. This species closely resemble B. saloteae ( Myers, 1985c) from Tonga. It differs in the expanded basis of the male pereopod 3 in hyperadult males, in the less ovoid propodus of the male gnathopod 1, the less elongate gnathopod 2 and in the less curved sternal processes of the male, which are restricted to segments 2–4. The long finger-like rounded process on the anterodistal margin of the male gnathopod 2 basis, distinguishes this species from other Great Barrier Reef Bemlos species.

Distribution. Australia. Queensland: Lizard Island ( Myers 1988b, current study). Indonesia: Sanur, Bali ( Krapp-Schickel & Myers 2006).
