Raphe filiform and straight. Raphe branches very slightly bent with external proximal raphe endings strongly deflected to the valve primary side (opposite to stigma) with small, rounded grooves on the stigma-bearing side. External distal raphe ends slightly hooked and terminate on the apex valve mantle. The valve mantle bearing one row of oblong areola. Internally, raphe straight, with proximal endings slightly bent, and distal raphe endings terminating in small helictoglossae. Transapical striae composed by 3-4(5) round to slightly elongate areolae. Internally, areolae covered by hymen forming continuous strip. Internal stigma opening with circular lipped structure. Internally, longitudal channel visible, with small silica flap on site opposite to stigma.</paragraph>
