Doowia dexterae Barnard & Drummond 1987 , male, 3.4 mm, AM P77831; female, 3.5 mm AM P77832, Lizard Island, Great Barrier Reef. Type locality. Redcliffe Beach , near Brisbane , Queensland , Australia ( 27º14’S 150º07’E ) . Description. Based on male, 3.4 mm , AM P77831. Head. Head lateral cephalic lobe absent. Eyes ovoid, adpressed at top of head. Antenna 1 peduncle article 1 subequal to article 2, subequal to article 3; article 2 subequal to article 3; flagellum with 4 articles; accessory flagellum absent. Antenna 2 flagellum with 12 articles. Maxilla 1 inner plate with 1 apical seta, with row of medial setae. Maxilla 2 inner plate with oblique setal row. Mandible palp present; article 1 shorter than article 2, subequal to article 3; article 2 longer than article 3; without basofacial setae; molar triturative; accessory setal row with 5 setae. Lower lip mandibular lobes apically rounded, with extensions directed axially. Maxilliped palp exceeding outer plate. Pereon . Coxae 1–7 subequal to depth of pereonites. Gnathopod 1 coxa with rounded distal expansion; carpus shorter than propodus; propodus subchelate, not distally expanded; dactylus reaching length of palm. Gnathopod 2 stout; carpus shorter than the propodus, cup-shaped, carpal lobe absent; propodus subchelate, palm subacute, entire, palm lined with robust setae, without robust setae defining posterodistal corner of palm; dactylus reaching length of the palm. Pereopods 3–6 fossorial. Pereopod 7 much longer than pereopods 5–6; basis posterior margin straight, smooth, posterodistal corner rounded, extending part way along ischium. Pleon. Epimera 2–3 posterodistal corners subquadrate. Urosomites 2–3 fused. Uropod 1 rami subequal in length; inner ramus with 3 robust setae, outer ramus with 1 robust seta. Uropod 2 rami subequal in length; inner ramus with 1 robust seta; outer ramus with 1 robust seta. Uropod 3 peduncle elongate, twice as long as broad; rami subequal in length; rami without robust setae. Telson subquadrate, with medial setae. Female (sexually dimorphic characters). Based on female, 3.5 mm , AM P77832. Gnathopod 1 carpus longer than propodus, carpal lobe present; propodus twice as long as broad. Gnathopod 2 slender; carpus longer than the propodus, carpus subtriangular, carpal lobe present, lobe about as long as broad; propodus twice as long as broad, palm acute. Habitat. Sandy beaches, surf zone. Remarks. Differences between Doowia dexterae and Doowia cooma Barnard & Drummond, 1987 , the two species of Doowia described from Australia , are very slight. The GBR material described here is larger than original material of D. dexterae but has less robust setae on the uropods, a character identified as increasing in number with size. The reduced number of robust setae on the uropods in combination with the 8 oblique setae on the inner plate of maxilla 2 (3 oblique setae in D. dexterae ) would appear to align the GBR material with D. cooma Barnard & Drummond, 1987 . However, the female GBR material examined has well developed carpal lobes on gnathopods 1–2 as in D. dexterae (weakly developed in D. cooma ). The male gnathopod 1 propodus palm in GBR material has a greater number of robust setae as in D. dexterae . I consider these later two characters to be more important for differentiating D. dexterae from D. cooma , and therefore assign the GBR species to D. dexterae . Distribution. Australia . Queensland : Redcliffe Beach, near Brisbane ( Barnard & Drummond 1987 ), South Bribie Island ( Barnard & Drummond 1987 ), Lizard Island (current study).
