Description

Description: The skeletal structure was as described by Lévi (1993) so the original description is translated in full here (from the French). “ Description. Sponge attached to various small calcareous debris, light gray-white in colour, measuring 20 / 15 / 2 mm. The surface is reticulated. The superficial film, very thin, contains sigmanistres and some diancistres. The main skeleton consists of bundles of styles in groups of three, associated in thick or crisscross bundles. Some packets arrange themselves radially around grains of sand. ” The spicules of the holotype were, however, examined in this study and measurements of spicules are included in Table 1 and compared to the original description of Lévi as well as another closely related species H. (V.) umisachii Ise, Woo, Tan & Fujita, 2019 from Japan and a new species Hamacantha (Vomerula) novacula sp. nov. from Australia.
