The single LAP described here displays the distinctive combination of relatively small spine articulations in notches of the weakly elevated distal edge, with the strongly protruding ventral portion of the LAP and the simple, slender ridge on the inner side devoid of sharp kinks and thickened parts, which unambiguously places it in the genus

. Within this genus, a number of species have up to six spine articulations but all of them display at least two spurs on the outer proximal and distal edge rather than a single, large, swollen, protruding area on the outer proximal edge and a moderately well-defined, round spur on the inner distal edge. This LAP clearly belongs to a new species, the formal description of which, however, should not be based on only a single specimen.
