Diagnosis This species differs from G. triangularis in the following counts. In G. annularis peristome is relatively small, 54-56.5% of the test diameter, while in G. triangularis the peristome is very large, 63-72.5% of the test diameter. Secondly, the periperoct outline of G. triangularis is triangular, having three sunken tubercles located alternatively adjacent to three genital plates. In G. annularis the periperoct is circular and there are no sunken tubercles. Thirdly, in G. annularis the test is hemispherical in profile, whereas in G. triangularis the profile of the test is rather domed. [details]
