Taxonomy: Margin. Somewhat serrate; thoracic and caudal thoracic pores normally small and irregular, sometimes blunt with tooth-like projections. Dorsum. Granular with reticulations surrounding the inverted tracheal clefts and forming a pattern extending mesad, but not reaching median area; caudal furrow also has reticulations that extend to and sometimes surrounds the vasiform orifice; subchordate vasiform orifice with an operculum that hides the lingula exposing its setose head.
