Sinoennea pagodella van Benthem Jutting, 1961
“Sinoennea pagodella has a narrower umbilicus than S. charasensis, perakensis, hungerfordiana or tweediei. From the large, spindle-shaped S. kanchingensis, the compressed malaccana and the very small lembingensis the new species differs in size, shape and ribbing. S. chintamanensis is like a double-size edition of S. pagodella, but has the two palatal teeth on a common base, whereas in S. pagodella they are distinctly separate. Moreover the peristome of S. chintamanensis is always adnate, reaching rather high up against the previous whorl, but in S. pagodella the peristome is generally just free from the last whorl and it does not reach so high. S. apicata is more spindle-shaped, has an adnate peristome and only a minute tooth at the edge of the columellar side of the aperture. It is, moreover, about twice as large as S. pagodella. S. crumenilla and S. chrysalis have a more ventricose shell, without a tooth at the edge of the columellar margin. S. chrysalis is, moreover, twice the size of S. pagodella. S. bacca is a much larger shell in which the vertical ribs curiously wear away in patches. The umbilicus of S. bacca is wider than in S. pagodella. S. gebula has a more obese larger shell and relatively smaller aperture. S. leucostolos and S. callizonus are agin of larger size. They lack the tooth at the edge of the columellar margin of the peristome.” (Benthem-Jutting, 1961)
Benthem-Jutting (1961) original descriptions on Sinoennea pagodella – “Shell high-ovoid or cylindrical-pupoid, probably glassy transparent in fresh shells, but opaque in dead shells. Two top whorls smooth, following ones with vertical, widely spaced ribs, about 15-16 on the last whorl. No spiral striation. Whorls 6-6½, the three first regularly increasing in diameter, the following ones of nearly equal width. Profile of each whorl convex, suture well impressed. Top blunt, base rounded, umbilicus narrow. Aperture almost vertical, quadrangular with rounded angles. Peristome continuous, adnate or just free from the penultimate whorl, broadened, reflected, with a strong, undulating lamella in the upper corner. On the palatal margin there are two knobs, the lower of which is strongest, corresponding with a depression on the exterior side of the last whorl, just behind the peristome. At the columellar side a knob-like tooth lies at the peristome edge, a second weaker elevation somewhat lower down in the throat. On the exterior side of the distal part of the last whorl there is a small groove or pit, corresponding with the lower columellar tooth. Between the groove and the peristome the shell is somewhat swollen in the umbilical region.”
Sinoennea pagodella – “Dimensions: Height 2.3-2.5 mm; Width 1.2-1.3 mm; Height of aperture 0.8-0.9 mm.” (Benthem-Jutting, 1961)
Type locality – “Malaya; Gua Bama, near Padang Tengku, Pahang” (Benthem-Jutting, 1961)
