According to Gilmour (1950): “The elytra very elongate, rather depressed, moderately, but distinctly dilated behind the middle, the humeri broadly rounded; the apices slightly bisinuate, the marginal angle terminating in a fairly long, sharp spine, the sutural angle rectangular.”Actually, the elytra in the holotype is not as elongated as reported and figured by Gilmour (1950) (about 7 times longer than prothorax) ( Fig. 52 ): it is more widened and shorter (about 6 times prothoracic length) ( Fig. 51 ). Furthermore, the elytral apex is wider than in his figure.
