description
Measurements (in µm). Hydrotheca: diameter at aperture 190 – 200, diameter at diaphragm 125, height 50. Hydrophore: adcauline length 300.
discussion
Remarks. The relatively long hydrophore and the shape and size of the hydrotheca allow a certain identification. It is worth mentioning the occasional presence of a pseudodiaphragm, faintly visible in stained material (Fig. 2 C).
materials_examined
Material examined. TAN 0102 / K 0809, a few stems up to 10 mm high, with putative male gonothecae, on tube of benthic organism (NIWA 144358).
