Microscleres include palmate isochelae, toxas and echinating acanthostyles. We described ten species from the Mexican Pacific Ocean. Six of them are new to science: <i>Acarnus michoacanensis</i> n. sp., <i>Acarnus oaxaquensis</i> n. sp., <i>Acarnus sabulum</i> n. sp., <i>Acheliderma fulvum</i> n. sp., <i>Megaciella toxispinosa</i> n. sp. and <i>Iophon bipocillum</i> n. sp.
