| Summary: | Halecium exaggeratum Peña Cantero, Boero & Piraino, 2013 (Fig. 2C) Material examined. TAN 0102/K0809, a few stems up to 10 mm high, with putative male gonothecae, on tube of benthic organism (NIWA 144358). Measurements (in µm). Hydrotheca: diameter at aperture 190–200, diameter at diaphragm 125, height 50. Hydrophore: adcauline length 300. 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. 2C). Ecology and distribution. The material, which represents the first record from the Balleny Islands, was collected at a depth of 292 m, off Young Island. Gonothecae present in March.
