Measurements [in µm] and pt values of selected morphological structures of individuals of Paramacrobiotus fairbanksi Schill, Förster, Dandekar & Wolf 2010 Albanian population 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, pt—ratio of the length of a given structure to the length of the buccal tube expressed as a percentage).
