Table 7 Measurements [in μm] of selected morphological structures of juveniles of N. cirinoi (Indomalayan specimens) mounted in Hoyer’s medium. Abbreviations: N – number of specimens/structures measured, RANGE refers to the smallest and the largest structure among all measured specimens; SD – standard deviation; sp – the proportion between the length of a given structure and the length of the scapular plate; ? – unknown

From: New Indomalayan Nebularmis species (Heterotardigrada: Echiniscidae) provoke a discussion on its intrageneric diversity
