Table 3. Measurements (in μm) and pt of selected morphological structures of individuals of Macrobiotus azzunae sp. nov. mounted in Faure-Berlese. Abbreviations: Nr = number of specimens/structures measured; Range = smallest–largest value; SD = standard deviation. * Three animals below 200 μm in length were not considered in the analysis. Two were not measurable, while data of the only measurable animal below 200 μm is available in the supplementary material (Supp. file 1).
