Description Specimen found on tree leaves. Southeast Borneo. Indonesia. January, 2015.

a stout variant of A. perversus pattern, whitish in background color, and rather similar to the Javanese subspecies, Amphidromus perversus emaciatus. It was described from South Borneo in the Bandjermassin District, but there are specimens in the Leiden Museum from East Borneo. The flammulations above the periphery are reduced in number. It differs from Amphidromus perversus emaciates primarily in the shorter, more ventricose form and consequently wider aperture.
