Description
Described (p. 453) as genus of Calymenidae but believed by SDZUY to belong in this subfamily of the Homalonotidae, as indicated by shape of glabella, nature of cephalic border, presence of distinct paraglabellar areas, and general cuneiform shape of exoskeleton. The exceptional relief of the cephalon is not viewed as a significant taxonomic character indicating calymenid affinities. Illustrations of the type species given here differ slightly from those in Fig. 354, 3, for example, in showing paraglabellar areas of the cephalon; sources of the compared figures are not exactly the same
