| contents | <p><b>Family Laetmogonidae Ekman, 1926</b></p><p><i>Diagnosis</i> (amended from Rogacheva et al., 2009). Ossicles wheel-shaped, scattered rods or (in <i>Laetmogone violacea</i>) spinous crosses or (in <i>Gebrukothuria</i>) rods only. Tube feet conspicuous, evenly distributed along entire ventrolateral radii, never fused into a brim. Midventral tube feet present or absent. Papillae numerous, placed along dorsal radii or dorsal and ventrolateral radii; papillae on dorsal radii free, on ventrolateral radii (if present) free or fused; in rare cases fused to form an anterior brim. Circumoral papillae present or absent. Calcareous ring reduced or not calcified. Gonad composed of numerous branched ducts and tubules.</p><p><i>Remarks.</i> The Laetmogonidae are a cosmopolitan family with seven currently accepted genera, three of which were previously recorded for Australia: <i>Benthogone, Laetmogone</i> and <i>Pannychia</i>. Found most commonly on the continental slope, these sea cucumbers have an elongated body with dorsal papillae and ventral-oriented feeding tentacles. IOT material includes examples from <i>Benthogone</i> and <i>Psychronaetes.</i> Diagnosis of family amended here to include rare case of fused anterior brim.</p> |
