Description.âCup small, conical, height equal to width, consisting of smooth, unornamented plates. In- frabasal, basal, and radial circlets comprising 25%, 45%, and 30% of cup height, respectively. Infrabasals five, pentagonal, height equal to or slightly greater than width (h/w = ). Basals five, height equal to width. CD interray basal heptagonal, remaining bas- als hexagonal. Radials five-sided, wider than high (h/w = ). Radial facets declivate, U-shaped, rela- tively wide, occupying 59%-65% width of radials. Anal X large, six-sided, height approximately equal to width, distal margin level with D ray radial facet but below C ray radial facet. XI pentagonal, situated above D ray radial, lower portion extending below dis- tal margin of C ray radial. Anal sac long, consisting of vertical rows of plates.
