Material examined. 1 male, AM P70645 (QLD 1634) ; 1 male, 2 females, AM P70683 (QLD 1641) .

Type locality. Off Barbers Point , Oahu, Hawaii, USA (~ 21°19'40''W 158°7'10''N) .

Description. Based on male, 6.0 mm, AM P70645, female, 5.9 mm AM P70683.

Head. Head lateral cephalic lobes apically truncate. Antenna 1 flagellum with about 20 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 straight, with setae of two distinct lengths, long setae and an under-story of much shorter regularly spaced setae.

Pereon. Pereonites 2–4 with apically acute sternal spines. Gnathopod 1 coxa unproduced anterodistally, rounded; basis robust, twice as long as broad, posterodistal margin with few setae; ischium anterior margin without flange, posterior margin with one long seta; merus not greatly elongated, fused along its entire length with carpus, posterior margin with few setae, without spine; carpus one third length of propodus, with few setae, anterior margin with no spine; without an oblique row of long setae on inner face, posterodistal margin without spine; propodus anterior margin weakly setiferous, posterior margin sinuous, palm present, delimited from posterior margin, forming a narrow sinus, with strong posterodistal spine, without spine near base of dactylus; dactylus more than half length of propodus, significantly overlapping palm. Gnathopod 2 subchelate; basis anterior margin weakly concave, anterodistal margin without flange, posterodistal margin without robust setae; with few setae along length of basis; carpus longer than propodus, with short sparse setae; propodus with moderately dense long setae, palm with robust seta defining palm. Pereopod 3 basis unexpanded, without brush of long setae on merus. Pereopod 6 basis weakly produced posterodistally. Pereopod 7 125% length of pereopod 6.

Pleon. Epimeron 3 posterodistal margin with small notch bearing a seta. Uropod 1 rami subequal, peduncle much longer than broad, distoventral spine shorter than peduncle. Uropod 2 biramous; peduncle with distoventral spine shorter than peduncle. Uropod 3 biramous, inner ramus nearly 2 x length of peduncle. Telson with distal fine setae only.

Female (sexually dimorphic characters). Based on female, 5.9 mm, AM P70683. Sternal spines absent. Gnathopod 1 basis relatively slender, about 3 x as long as broad; carpus about two thirds length of propodus, palm defined by a rounded corner and a stout robust seta; dactylus overlapping palm. Gnathopod 2 basis slender, anterior margin straight to weakly convex, carpus and propodus subequal in length.

Habitat. Coral rubble often with algae and epiphytes over sandy bottoms in shallow water. Remarks. Bemlos waipio could only be confused with B. clypeatus , but differs in lacking a spine on the anterodistal margin of the basis in the male gnathopod 2 and in the unexpanded basis of the male pereopod 3. Distribution. Australia. Queensland: Lizard Island. Hawaii. Oahu (J.L. Barnard 1970). Caroline Islands. Ifaluk Atoll (J.L. Barnard 1965). Vanuatu: Efate Island ( Myers 1985c). Papua New Guinea. Madang lagoon ( Myers 1995). New Caledonia. South-west Lagoon, Noumea ( Myers 1998).
