Middle zone having whitish gray color separated by edge of subsutural band posteriorly and fasciolar band of yellowish white color anteriorly. Ground color whitish gray with indistinct markings. Fasciolar band delimited from basal zone by a weak line. These two bands at a glance appear to be a single one. Basal zone delimited from columella with oblique folds and deep furrow.
