Type locality. 5.5–6.5 km off Wattamolla , New South Wales, Australia, [approximately 34°10'S 151°11'E], 99–108 m depth GoogleMaps   .

Diagnostic description. Head lateral cephalic lobe subtriangular, apically rounded; eyes apparently absent. Antenna 1 peduncular articles 1 and 2 without anterodistal lobe; accessory flagellum not forming cap, terminal article not offset; flagellum with weak 2-field callynophore, robust setae absent from proximal articles; calceoli absent. Antenna 2 peduncular article 3 short; peduncular articles 4 and 5 not enlarged; flagellum short, calceoli absent. Epistome/Upper lip separate; epistome produced slightly beyond upper lip, broadly rounded; upper lip not produced, straight. Mandible molar with asymmetrically reduced column, proximally setose, distally triturating; article 3 with proximal A3-seta. Maxilla 1 setal-tooth 7 left and right symmetrical, cuspidate along most of sinusoidal inner margin; palp distal margin with apical robust setae. Maxilliped basis without recurved hook; outer plate with 2 short apical robust setae.

Gnathopod 1 subchelate; coxa medium length (length 1.6 x breadth), subtriangular, tapering distally; basis sparsely setose along anterior margin; ischium short; carpus long, subequal in length to propodus, without posterior lobe; margins subparallel, palm slightly acute. Gnathopod 2 palm slightly obtuse. Pereopod 4 coxa without distinct lateral ridge, with a well-developed posteroventral lobe. Pereopod 5 coxa without distinct lateral ridge, without umbo; basis about as long as broad, without photophore, not posteroproximally excavate, posterior margin weakly serrate. Pereopod 7 basis posterodistally produced less than halfway along merus, not posterodistally excavate.

Pleonites 1–3 without mid-dorsal carina, not produced dorsodistally. Epimeron 3 posterior margin smooth, posteroventral corner subquadrate. Urosomite 1 with deep notch and subtriangular, subacute boss. Uropods 1 and 2 outer rami without stout striated robust setae. Uropod 2 inner ramus without constriction. Uropod 3 peduncle without dorsolateral flange, with 1 short apicomedial robust seta; inner and outer rami well developed, outer ramus article 2 short, without plumose setae on rami. Telson   moderately cleft, with dorsal robust setae, with 1 apical robust seta on each lobe.

Male (sexually dimorphic characters). Head lateral cephalic lobe a semidome, apically truncated. Antenna 1 flagellum with strong 2-field callynophore; calceoli present, proximal calceolus very large. Antenna 2 peduncular articles 4 and 5 enlarged, proximal calceolus very large; flagellum long, calceoli present. Uropod 3 with plumose setae on both rami.

Remarks. Tryphosella camela   is most similar to T. cameloides Lowry & Stoddart, 2009   . Both species have a distinctive subtriangular, subacute boss on urosomite 1. In T. camela   this boss is more robust and is preceded by a very deep incision whereas in T. cameloides   the boss is laterally very thin. The two species also differ slightly in the shape of the basis of pereopods 5 to 7 and in the number of apical robust setae on the maxilliped outer plate (two in T. camela   , three in T. cameloides   ).

Tryphosella camela   occurred in low numbers (1– 6 specimens) from 50 to 200 m depth from northern Queensland to southern Victoria. In Bass Strait and Tasmania it occurred in samples down to 400 m depth, but still in low numbers. Although it was taken in baited traps all along the coast it was also captured in sledges and grabs   .

Distribution. Eastern Australia, from north Queensland to Tasmania, 1.5–400 m depth.
