on account of the massive, nearrectangular aspect of the main portion, the strongly protruding ventral portion, the shape and arrangement of the spine articulations and the shape of the ridge on the inner side. Within this genus, the LAPs described above are unique in entirely lacking vertical striation on the outer surface and spurs on the outer proximal and inner distal edges.
