The surface fine structures of Ixodes persulcatus (Schulze, 1930) male and female specimens were observed by means of a scanning electron microscope. A brief review on the biology of the ticks and their disease relationships was also presented. The sexual dimorphism of the specimen was marked; the male was quite smaller than the female. The genital groove was well developed and deep, the anal groove was distinct and characteristically extending anteriorly around the anus. The 4th article was much reduced and situated on the top of the 3rd article ventrally. The hypostome dentition was usually 3/3. The bottom of the basis capitulum of the male specimen was strictly straight in shape. This species was regarded as one of the most important vectors for infectious diseases of migrating birds.
Figs. 1-2 Ixodes persulcatus (Schulze, 1930) male and female specimens. Scanning electron microscope (ISI-DS-130, 20 KV).
Fig. 1. Aspect of coitus in Ixodes persulcatus adult ticks. Notice the large one is a partly fed female showing the specific anal groove extending anteriorly around the anus and the distinct genital groove, while the small one is a male showing the specific lateral groove and the palpi. (16.2×)
Fig. 2. Ventral aspect of the female coccygeal part showing the anus and the anteriorly extending anal groove. Notice the distinct genital groove, setae and finger prints on the surface of the abdomen. (39×)

Fig. 3. Ventral view of the female capitulum showing the hypostome, articles with ventrointernal setae, ventral process, corona files and some parts of the leg 1. (80×)
Fig. 4. Dorsal view of the male capitulum showing the articles with ventrointernal setae and the hexagonal basis capitulum. Notice the setae long and short on the surface of the scutum. (189×)
