The holotype of Palawanosorex ater largely matches the external and cranial measurements of P. ater specimens captured in Sarawak, not P. muscorum. Each panel represents a measurement, and the y-axis represents the measurement length in mm. Each species is represented by a different shape. The upper and lower bounds of the point intervals represent the maximum and minimum values for each measurement for each species. Measurements are limited to those reported in the description of Suncus ater (Medway 1965). Palawanosorex ater measurements are taken from six specimens collected in Sarawak, Malaysia. Palawanosorex muscorum measurements are taken from Hutterer et al. (2018: tables 1, 2). LSUMZ 40695 has a cropped tail and was removed from the total length and tail length measurements.
