Extension of genal roll and brim on prolongations quickly steepens posteriorly to near vertical. Girder turns gently upwards on prolongations, to meet internal rim nearly halfway down. Row of larger perforations below internal rim. Viewed dorsally, external rim flexes slightly abaxially as it crosses onto prolongation, straightens, and then curves adaxially to meet internal rim, which points obliquely adaxially. Internal rim is angled about 30° to posterior border, pointing obliquely abaxially, and then curves steadily adaxially posteriorly, to join with external rim at end of prolongation. Prolongation terminated by long genal spine, which extends from lower lamella and points adaxially at an angle of about 50° to exsagittal line. Viewed laterally, internal rim declines steadily posteriorly to meet external rim, which is slightly upturned at its distal end. Dorsal surface of internal rim is initially flat but becomes rounded close to junction with external rim. Intermittent row of fine tubercles runs along outside edge of flat surface.
