Anterior petal shorter than the rest. Periproct inframarginal, large, longitudinally elongate. Peristome large, subcentral, oblique with long axis running from amb. II to Iamb. 4; depressed. Pore-pairs uniserial except close to peristome where they become slightly offset. Plating simple. No buccal pores.
