Diagnosis A genus of Thysanometrinae in which the radial facets have long narrow triangular muscular fossae, separated from the interarticular ligament fossae by strongly diagonal and sraight ridges; the centrodorsal is hemispherical or subconical; the distal pinnules tend to be shorter than the proximal one. The color pattern is apparently characteristic of the species. [details]
