Zeidler; 1 male, MV J62308 north side of West Island, Encounter Bay, 35°37'S 138°36'E, 4 m, sand patch in <i>Heterozostera</i> meadow, 21 March 1985, G.C.B. Poore &amp; H.M. Lew Ton, stn MV SA-48. <b>Diagnostic description.</b> <i>Head</i> lateral cephalic lobe subtriangular, apically rounded; eyes red (fading in alcohol), large, subtriangular with ventral concave lens. <i>Antenna 1</i> flagellum with strong 2-field callynophore, robust setae absent from proximal articles; calceoli present. <i>Antenna 2</i> peduncular articles 4 and 5 not enlarged; flagellum short, calceoli absent. <i>Epistome/Upper lip</i> epistome less produced than upper lip, straight. <i>Mandible</i> molar with asymmetrically reduced column, proximally setose, distally triturating. <i>Maxilla 1</i> outer plate setal-tooth 7, left and right symmetrical, cuspidate along most of straight inner margin; palp distal margin with apical robust setae. <i>Maxilliped</i> outer plate with 2 short apical robust setae. <i>Gnathopod 1</i> subchelate; coxa large (length 1.9 x breadth), subrectangular, distally subovate; basis moderately setose along anterior margin; ischium short (length 1.5 x breadth); carpus long (length 2.1 x breadth), subequal in length to propodus, without posterior lobe; propodus margins subparallel, palm moderately acute. <i>Gnathopod 2</i> propodus palm moderately obtuse. <b> <i>Pereopod 4</i> coxa with distinct lateral ridge</b> . <b> <i>Pereopod 5</i> coxa with distinct lateral ridge</b> ; basis about as long as broad, with photophore. <i>Epimeron 3</i> posterior margin smooth, posteroventral corner broadly rounded. <i>Uropod 3</i> outer ramus article 2 short, with plumose setae on both rami. <i>Telson</i> deeply cleft, with dorsal robust setae, with 1 or 2 apical robust setae on each lobe. <b>Male</b> (sexually dimorphic characters). <i>Antennae 1 and 2</i> calceoli present. <i>Antenna 2</i> peduncular article 4 slightly enlarged. <b>Remarks.</b> According to Lowry &amp; Stoddart (2009) <i>P. charlotteae</i> is most similar to <i>P. mucronata</i> (Pirlot, 1936). Both species have a well developed photophore on the basis of pereopod 5, but only <i>T. charlotteae</i> has a strong lateral ridge on the pereopod 4 coxa. Lowry &amp; Stoddart (2009) recorded <i>T. charlotteae</i> from the Great Barrier Reef as far south as Moreton Bay. In this paper we extend the range south to Bass Strait. There is a great deal of variation in the honeycomb appearance of the cuticle in this species. In the material reported by Lowry &amp; Stoddart (2009) there was almost none present; the specimen illustrated in Figure 1 shows a very strong form. We cannot see any pattern to this variation and its loss might be an artefact of preservation. <b>Distribution.</b> Eastern and southern Australia; 4–15 m and 57–82 m depth.
