Table 12 Measurements [in μm] of selected morphological structures of individuals of Macrobiotus margoae sp. nov. from the USA (US.057) mounted in Hoyer’s medium (N–number of specimens/structures measured, RANGE refers to the smallest and largest structures among all measured specimens; SD–standard deviation)

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