Hemiplecta rabongensis E. A. Smith, 1895
“This species, which may possibly be a dextral Dyakia, is quite distinct from H. densa or H. egeria. It has a more raised spire than the latter, is more strongly sculptured both above and beneath, and is less glossy upon the under surface. H. densa is more widely umbilicated, is differently sculptured, and has much more rapidly enlarging whorls, which also, in shells of the same dimensions, are fewer in number.” (E. A. Smith, 1895)
