Taxonomy The very peculiar shape of the tentacles make this species easily recognisable. Although Mayer observed several specimens, the species has not been found again. The absence of ocelli is a good argument for not allocating this species in the Corynidae. New life cycle observations and information on the nematocysts are needed to allow a correct placement of this species. It is presently best classified as Anthoathecata incerta sedis. [details]

description (after Mayer, 1910) bell about 4 mm high, 3 mm wide, with thin, uniform walls and a slight apical projection. With two equally-developed, diametrically opposed tentacles, each about 3/4 as long as bell-height. Near the distal end of the tentacles a knob-like swollen region, hollow, with a thin terminal process. Marginal bulbs small, without ocelli. In addition to the large tentacles there are 2 small, tapering, rudimentary tentacles placed at 90° to the large tentacles. Four narrow, straight radial canals and circular canal present. Manubrium flask-shaped, thickened in middle region. The gonads develop around the manubrium. The rudimentary tentacles may occasionally develop so as to be nearly as long as the pair of large tentacles. [details]
