description: <i>Birubius kingae</i> sp. nov. (Figs 7, 8) <b>Type material.</b> Holotype female, 4.0 mm, AM P77841, Lizard Island (14°40’S 145°28’E), light trap at night in 3 m of water over reef flat, 3 m, Smith &amp; Marshall, September 1976 (QLD 2015). Paratypes: 15 females, 2.5 mm –4.0 mm AM P77842, same station data. <b>Type locality.</b> Lizard Island, Queensland, Australia. <b>Etymology.</b> Named for crustacean taxonomist Dr Rachael King who assisted in the sorting and initial identification of the material collected at the workshop held in Lizard Island. <b>Description.</b> Based on holotype female. <b>Head.</b> <i>Rostrum</i> constricted; eyes present (red pigmented in preserved specimens). <i>Antenna 1</i> peduncle article 2 with ventral setae situated proximal to midpoint. <i>Antenna 2</i> peduncle article 4 facial robust setae not in a single row, dorsal setae present; article 5 midfacial robust setae present as a single set of 2; flagellum multiarticulate. <i>Mandible palp</i> article 2 without outer setae; <i>molar</i> simple, form D; right molar with 4 spines, without disjunct spines, right incisor with 3 teeth, right lacinia mobilis simple, with right raker row of 9 teeth. <i>Maxilla 1</i> inner plate with 3 setae; outer plate without an especially thickened robust seta. <i>Maxilliped</i> inner plate with 1 large thin-thick apical robust seta; outer plates, inner margin with well developed setae. <b>Pereon.</b> <i>Coxae</i>, long ventral setae present on coxae 1–3 but absent from coxa 4, main ventral setae of coxae 1–4 = 5–5–6–0. <i>Coxa 1</i> expanded distally. <i>Gnathopods</i> similar. Gnathopod 1 palms oblique. <i>Pereopods 3–4,</i> carpus with 1 posteroproximal robust setae, propodus slender setae absent. <i>Pereopod 5</i> basis of broad form, not tapering distally, without facial ridge. <i>Pereopod 6</i> basis without facial ridge. <i>Pereopod 7</i> basis with few or no long ventral setae, with 2 facial ridges. <b>Pleon.</b> <i>Epimeron 1</i> anteroventral margin with 3 setae, posteroventral face without setae. <i>Epimeron 2</i> with 7 facial setae, crowded anteriorly. <i>Epimeron 3</i> with fully facial setae arranged in oblique row, posterior setae absent, with 2 ventral setae. <i>Uropod 1</i>, peduncle basofacial setae absent, without major displaced robust setae, with 1 apicolateral spine; inner ramus with 2 dorsal spines, without subapical accessory robust seta; outer ramus not continuously spinose to apex. Uropods 1–2 rami with well developed apical nails. <i>Uropod 3</i> outer ramus article 2 with 2 apical setae. <b>Habitat.</b> Collected in light traps at night in 3 m depth. <b>Remarks.</b> This new species of <i>Birubius</i> can be diagnosed from all other species of the genus by the combination of the following traits; right lacinia mobilis simple, coxa 1 expanded distally with 5 long ventral setae; pereopods 3–4 carpus with 1 posteroproximal robust setae, epimeron 3 with facial and ventral setae, absence of basofacial setae on uropod 1. <b>Distribution.</b> Australia. Queensland: Lizard Island (current study).
