Pereopod 7 longer than pereopod 6, both longer than pereopod 5.</p><p>Pleon (based on male, 8.59 mm, AM P.100148). Uropod 1 bi-articulate; peduncle, length about 0.5 times width, with 3 lateral setae; ramus length about 5 times peduncular length, with 9 or 10 shorter setae. Telson (dorsal lobe) present with paired setae.</p><p>Female (based on paratype, 6.02 mm, AM P.100149). Head with paired anteriorly curved dorsal projections, with small subocular projection; eye large, distinctive. Antenna 1 slender, 0.85 times body length; peduncle article 2 longest; flagellum longer than peduncular length, with + 17 articles. Pereonite 2 with 2 small anterolateral projections, with paired anteriorly curved mid-dorsal projections, with curved dorsodistal projection. Pereonite 3 with small anterolateral projection, with midlateral projection, with paired anteriorly curved mid-dorsal projections, with dorsodistal projection. Pereonite 4 small with anterolateral projection, with dorsolateral projection. Pereonite 5 with 2 small anterolateral projections. Pereonites 6 and 7 not articulated obliquely. Gnathopod 2 inserting at anterior margin of corresponding pereonite; coxa vestigial; basis 0.8 times length of pereonite 2, with triangular projection; propodus subovate.</p><p>Remarks. During a field survey of One Tree Island, southern Great Barrier Reef in October–November, 2006, Circum-Australian Amphipod Project, Metaprotella were collected from the outer reef of One Tree Island lagoon at around 15 m depth. The Metaprotella from One Tree Island closely resembles but clearly differs from M. sandalensis [sensu stricto] (Lim &amp; Takeuchi, 2012) or other members of the M. sandalensis complex, justifying its establishment as a new species, Metaprotella lowryi sp. nov. Metaprotella lowryi differs from M. sandalensis in the following characteristics: (1) antenna 1 is 0.6 times body length (versus 0.8 times body length in M. sandalensis); (2) antenna 1 peduncle article 3 is shorter than article 2 (versus longer than article 2 in M. sandalensis); (3) the gnathopod 2 propodus palm lacks serratiform teeth (present in M. sandalensis); (4) the dorsodistal projection of both pereonites 2 and 3 is more anteriorly curved in M. sandalensis than in M. lowryi .</p><p>Metaprotella lowryi is also close to M. solitaria Takeuchi &amp; Lowry, 2017 (type locality: Solitary Islands, New South Wales). The new species differs from M. solitaria by the following characteristics; (1) the paired dorsal projections of the head are anteriorly curved (versus straight in M. solitaria); (2) the gnathopod 2 propodus palm has a small distal shelf with sinus and distal palm projection, distinctly developed in the larger male (AM P.100148) (versus two distal palm projections in M. solitaria); (3) mid-dorsal projections of pereonite 3 are anteriorly curved (versus straight in M. solitaria); (4) dorsodistal projection of pereonite 3 is anteriorly curved (versus dorsally directed in M. solitaria); and (5) pereonite 5 is longer than pereonite 4 (versus shorter in M. solitaria).</p></div>	https://treatment.plazi.org/id/F17187C16B5DFFD0FC2FCE17BEEAF832	Public Domain	No known copyright restrictions apply.
