title: Table 6 in The genus Milnesium (Eutardigrada, Apochela, Milnesiidae) in Argentina: description of three new species and key to the species of South America

description: Table 6 (continued on next page). Measurements (in μm) and pt values of selected morphological structures of specimens of Milnesium irenae sp. nov. mounted in polyvinyl-lactophenol medium. Range refers to the lowest and the highest values among all measured specimens. Pt values are provided in italics. Abbreviations: N = number of specimens or structures measured; SD = standard deviation.
