Table 6 Measurements [in μm] of selected morphological structures of adult females of Cornechiniscus holmeni mounted in Hoyer’ s medium. 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.| CHARACTER | N | RANGE | | | | | | MEAN | | SD | |
