Diplommatina lenggongensis lenggongensis Tomlin, 1941
“This species is closely related to superba Godwin-Austen and G. Nevill, but is more elongate, more bluntly keeled, and differs radically in axal sculpture; the costulae in superba are very close and very obliquely sloped.” (Tomlin, 1941)
“The longest and largest of the Malayan species.” (Laidlaw, 1949)

Aperture almost circular with a tubercle on the columella.”
