Megjegyzések:	There is very few data in the literature about the morfometry of dragonfly species including Lestes barbarus. Our work aimed at increasing the amount of data concerning this species, exploring the variation in the focal marksand comparing the sexes. The study is based on the body- and wing-marks of 15 male and 15 female adults from the marsh Fancsikai-mocsár, North-East Hungary.We measured the following parameters: total body length, total abdomen length,five marks on the head, two on the legs, 12 on the anal appendages of the males and seven on the abdominal tip of the females. We measured the area of the wings and the distance between eight selected points on them. The cross-veins in three rows of cells and the cells in eight rows of cells were counted as well. We used not only the mean, SD, maximum and minimum values to the comparison, but the coefficient of variation and the difference between the minimum and maximum values relative to the mean values. Furthermore we used SHAPIRO&WILK,Student-t and MANN&WHITNEY tests, principal component analysis, canonical discriminant analysis and linear regression between selected marks. We found that total body length and total abdomen length of the males were significantly larger than the females', although females were significantly larger in the marks of head,legs and in wing-size. In case of the body-marks, variance was more significant in the abdominal tip. Considering the wings, larger differences were found in the number of cross-veins and cells. Principal component analysis showed a slightoverlap in the convex hull of the body-marks and the wing-sizes of the two sexes,while discriminant analysis showed a full separation in both cases. Linear regression showed highly significant correlation for 20 mark-pairs but found no significant correlation in 68 cases. The total body length showed the maximal number of highly significant correlations, while the most numerous correlations with the different marks were at the head's marks.
