Thorax spherical with a large, circular basal aperture (pylome) with narrow, slightly elevated pylome rim. Single layer of latticed meshwork with irregular polygonal pore frames. Seven triradiate spines distributed on thorax surface: three on the upper hemisphere; four divergent and slightly curved feet evenly distributed surrounding the pylome margin.
