Lowry, stn WA-178. <b>Diagnostic description</b>. <i>Head</i> lateral cephalic lobe rounded, apically rounded; eyes lageniform (but fading in alcohol). <i>Antenna 1</i> peduncular articles 1 and 2 without anterodistal lobe; accessory flagellum not forming cap, terminal article not offset; flagellum with strong 2-field callynophore, robust setae absent from proximal articles; calceoli absent. <i>Antenna 2</i> peduncular article 3 short; articles 4 and 5 not enlarged; flagellum short, calceoli absent. <i>Epistome/Upper lip</i> separate; epistome produced beyond upper lip, broadly rounded; upper lip slightly produced, rounded apically <i>Mandible</i> molar with asymmetrically reduced column, proximally setose, distally triturating; article 3 with proximal A3-seta; palp distal margin with apical robust setae. <i>Maxilliped</i> outer plate with 2 short apical robust setae. <i>Gnathopod 1</i> subchelate; <b>coxa small (length 1.1 x breadth), subtriangular, tapering distally</b>; <b>basis sparsely setose along anterior margin</b>; ischium short; carpus long, subequal in length to propodus, without posterior lobe; propodus small, margins subparallel, palm slightly acute, entire, straight. <b> <i>Gnathopod 2</i> propodus palm slightly obtuse</b> . <i>Pereopod 4</i> coxa without distinct lateral ridge, with a well-developed posteroventral lobe. <i>Pereopod 5</i> coxa without distinct lateral ridge, without umbo; basis about as long as broad, not posteroproximally excavate, posterior margin weakly serrate. <i>Pereopod 7</i> basis posterodistally produced less than halfway along merus, not posterodistally excavate. <i>Pleonites 1–3</i> without mid-dorsal carina, not produced dorsodistally. <i>Epimeron 3</i> posterior margin smooth, <b>posteroventral corner narrowly rounded</b>. <i>Urosomite 1</i> not projecting over urosomite 2, with anterodorsal notch and slightly rounded boss. <b> <i>Uropods 1 and 2</i> outer rami with distal stout striated robust setae.</b> <i>Uropod 2</i> inner ramus without constriction. <i>Uropod 3</i> peduncle without dorsolateral flange, with 2 short apicomedial robust setae; inner and outer rami well developed, outer ramus article 2 short, without plumose setae on rami. <i>Telson</i> deeply cleft, with dorsal robust setae, with 1 apical robust seta on each lobe. Male (sexually dimorphic characters). <i>Head</i> lateral cephalic lobe a semidome. <i>Antenna 1</i> calceoli small. <i>Antenna 2</i> peduncular articles 4 and 5 enlarged; flagellum long, calceoli present. <i>Urosomite 1</i> with anterodorsal notch and rounded boss. <i>Uropod 3</i> with 1 short apicomedial robust seta; with plumose setae on both rami. <b>Remarks.</b> <i>Tryphosella orana</i> is one of the group of six Australian species with stout striated robust setae on the outer rami of uropods 1 and 2 (see Remarks under <i>T. fortescue</i>). <i>Tryphosella orana</i> is most similar to <i>T. tathra</i> – see Remarks under that species. <b>Distribution.</b> Southern Western Australia, intertidal to 14 m depth.
