Type locality. East of Cape York , Australia, Coral Sea, 10°32.72'S 144°12.8'E, 780–795 m depth .

Description. Based on holotype female, 6.8 mm. Head with lateral cephalic lobe subtriangular, apically subacute; eyes apparently absent. Antenna 1 peduncular articles 1 and 2 without anterodistal lobe; accessory flagellum 2-articulate, terminal article small, offset; flagellum with strong 2-field callynophore; robust setae present on proximal articles; calceoli absent. Antenna 2 flagellum short, calceoli absent. [Epistome/upper lip unknown]. Mandible molar columnar with oval, fully triturating surface; palp attached distally, article 3 with proximal A3-seta. Maxilla 1 outer plate with left and right setal-tooth 7 symmetrical, cuspidate distally along inner margin; palp distal margin with apical robust setae. Maxilliped outer plate with 2 (one slender, one broad) apical robust setae.

Gnathopod 1 subchelate; coxa large, about as long as coxa 2, subrectangular with straight anterior margin; basis sparsely setose along anterior margin; ischium short; carpus long (2.3 × breadth), longer than propodus, without posterior lobe; propodus small, margins subparallel, palm slightly acute. Pereonite 2 without mid-dorsal carina. Gnathopod 2 palm transverse. Pereonite 3 without mid-dorsal carina. Pereonite 4 without mid-dorsal carina. Pereopod 4 coxa with a weak posteroventral lobe (posterior margin concave). Pereonite 5 without mid-dorsal carina. Pereopod 5 coxa with distinct lateral ridge; basis about as long as broad, posterior margin with mid-central spine, with welldeveloped wedge-shaped posteroventral lobe. Pereonite 6 without mid-dorsal carina. Pereonite 7 without mid-dorsal carina. Pereopod 7 basis posterodistally produced, not reaching merus, not posterodistally excavate.

Pleonite 1 without mid-dorsal carina. Pleonite 2 without mid-dorsal carina. Pleonite 3 with mid-dorsal carina, not dorsodistally produced, posterodorsal margin produced. Epimeron 3 posterior margin smooth, posteroventral corner broadly rounded. Urosomite 1 with deep notch and subtriangular, acutely produced boss. Uropod 3 outer ramus article 2 short; with plumose setae on each ramus. Telson deeply cleft, with dorsal robust setae, with 1 apical robust seta on each lobe.

Etymology. Named for Luis Vaez de Torres, commander of the San Pedro, which, in 1606, was the first European vessel to sail through the strait that now bears Torres’ name.

Distribution. Coral Sea, western South Pacific Ocean; 780– 795 m depth.
