Measurements are provided in Table 2. Holotype dimensions and summary of shell measurements (mean, maximum (max), minimum (min), and standard deviation (sd)) of type material of Zospeum zaldivarae sp. n.: SH – shell height, SW – shell width, HLW – height of last whorl, PH – peristome height, PD – peristome diameter, SA – spire angle, W – number of whorls, CT– coiling tightness. SA in degrees, other measurements in mm.
