Oophana eutropha van Benthem Jutting, 1954
“The new species is related to Oophana (Haploptychius) pellucens (Pfr.) an to O. (H.) michaui (Crosse & Fisher), but has coarser ribs than either of these, much coarser than O. (H.) pellucens. The spire is more like that of O. (H.) michaui, and is not so pointed as in O. (H.) pellucens. The parietal lamella is bout twice as long as in O. (H.) pellucens and O. (H.) michaui.” (Benthem-Jutting, 1954)
Benthem-Jutting (1954) original descriptions on Oophana (Haploptychius) eutropha – “Shell short cylindrical-globular, creamy white. Probably transparent in live specimens, but the type and paratype, which comprise the available series, are opaque. Somwhat shining, especially on the basal side. Whorls 6-6 ½. First 2 ½ whorls smooth, the following ones ornamented on their upper side with transverse ribs, about 4 to the mm on the last whorl near the aperture, and about twice as much on the the preceding ones. One the base of the shell the ribs fade away. All whorls evenly rounded, the two last somewhat more convex than the preceding ones. About four whorls are regularly built, but the 2-2 ½ last whorls are obliquely pressed to the right so that the fourth whorl bulges out somewhat in the shell profile, and the entire shell gets a slightly eccentric aspect. Suture distinct, but not deep. Top somewhat projecting, but not sharp. Base rather inflated. Umbilicus narrow. Aperture oblique, rounded-trigonal to oal. Peristome not continuous, thickened and reflected, without teeth. In the upper peristomal margin the region closest to the shell protrudes somewhat. Parietal lamella almost straight, entering the aperture for about 2 mm.”
Oophana (Haploptychius) eutropha – “Dimensions; Width 8.9-9.6, height 9.2-11.0, height of aperture 5-6 mm, Greatest diam. 10.2-11.3.” (Benthem-Jutting, 1954)
Type locality – “Bukit Chintamanis, near Bentong, Pahang” leg. Benthem-Jutting/Aug. 1935 (Benthem-Jutting, 1954)
