Table 10 Measurements [in μm] of selected morphological structures of individuals of Macrobiotus ripperi sp. nov. from Poland (PL.015) mounted in Hoyer’s medium (N–number of specimens/structures measured, RANGE refers to the smallest and the largest structures among all measured specimens; SD–standard deviation)

From: Integrative taxonomy resolves species identities within the Macrobiotus pallarii complex (Eutardigrada: Macrobiotidae)
