Partially engorged Ixodes canisuga and I. kaiseri nymphs (dorsal views – upper panels, ventral views – lower panels) collected from Meles meles in Slovakia. Differences are seen in the shape of scutum (a) which is shorter in I. canisuga than in I. kaiseri. There is a broad internal spur on coxa I (b) in both species. Photo: Ľ. Vidlička
