Diagnosis. Up to 175 mm long, up to 35 mm diameter (preserved, tentacles withdrawn, largest WAM Z8994), cylindrical body with slight anal taper, thick soft body wall; external anal scales not detected; 20 tentacles, 5 outer pairs large, 5 inner pairs small; complete cover of close tube feet, not contiguous, sometimes more concentrated ventrally than dorsally, diameter about 0.7 mm, radial to scattered tube feet cross introvert; calcareous ring with 10 posterior composite tapering projections arising predominantly from radial plates but sometimes jointly from both radial and inter-radial plates, posterior ends free thin tails comprising small elongate plates, ring not tubular, posterior projections shorter than combined height of plates and anterior projections, form of plates and composite components variable; short stone canal, madreporite multi-lobed, close to vascular ring; up to 5 polian vesicles, variable sizes, frequently one; longitudinal muscles flat, longitudinal indentation along centre of muscle; gonad tubules arise in series along gonoduct on each side of dorsal mesentery, tubules not branched.

Mid-body wall lacking ossicles; tube foot ossicles endplates and support rods and narrow plates only; endplates with denticulate or smooth margin, irregular perforations similar size, endplate diameters up to 480 µ m; endplate support rods and narrow plates straight to curved, larger ossicles perforate and denticulate, up to 200 µ m long; tentacles with rods and rosettes, larger rods branched and denticulate distally, sometimes with small perforations, up to 160 µ m long, rosettes oval to irregular, up to 80 µ m long; peri-oral region with tentacle-like rods and rosettes; introvert with rosettes, fine rods up to 80 µ m long; anal ossicles tube foot endplates and support rods, tentacle-like rods, rosettes, 5 scales with base up to 320 µ m wide and digitiform column up to 360 µ m long, base and column comprising massed short branched rods.

Juveniles. For specimen 20 mm long tentacles 20; for specimen 10 mm long tube feet radial only; for specimen 15 mm long calcareous ring cucumariid-like, lacking posterior projections, not composite; for specimens 7 mm long and smaller, tables present in mid-body wall, discs regular and irregular with frequently 8 perforations, lobed margin, discs typically 72 µ m long, spires with 4 pillars, spires up to 64 µ m long.

Colour (preserved). Body pink-brown, dark brown orally and anally; tube feet off-white; large tentacle branches dark brown, trunks off-white, small tentacles off-white.

Distribution. Southern Australia, from E Victoria, Cape Conran, west to S Western Australia (Yanchep); rocky shallows, 0– 5 m.

Remarks. Cherbonnier 1988 referred five small specimens (up to 20 mm long) from Madagascar to Lipotrapeza ventripes ( Joshua and Creed, 1915) . As noted above and discussed below we make Lipotrapeza ventripes ( Joshua and Creed, 1915) a subjective junior synonym of Phyllostauros vercoi ( Joshua and Creed, 1915) . In his observations Cherbonnier 1988 based his referral of these specimens to Lipotrapeza ventripes on Clark 1938. We judge from their descriptive remarks that both authors are referring to Lipotrapeza vestiens ( Joshua, 1914) . The Madagascar specimens have the diagnostic characters of the presence of tentacle rods, the form of the calcareous ring, presence of tube foot endplates and support rods, and absence of ossicles in the mid-body wall that characterize Lipotrapeza vestiens . But Lipotrapeza vestiens specimens attain a much larger size (up to 175 mm long), have five distinct pairs of inner small tentacles (not two circles of five), do not normally have fewer dorsal than ventral tube feet, and lack the “pseudoplates” referred to by Cherbonnier 1988. We judge that the Madagascar specimens are not Lipotrapeza vestiens . Lipotrapeza vestiens ( Joshua, 1914) is distinguished from the other species of Lipotrapeza in the key (above).
