Scanning electron microscopic observations on the surface structure of the tick Boophilus microplus(Canestrini, 1887)...

Boophilus microplus (Canestrini, 1887) female specimens were subjected to scanning electron microscopy for the observation of surface fine structures. Morphological characteristics observed were summarized as follows: The palpi were wider than long, and compressed, ridged dorsally and laterally. There were usually four pairs of ventro-internal setae on the articles. The hypostome dentition was usually 4/4 but occasionally 5/5. The basis capituli were hexagonal dorsally and the porose area was distinct with the holes developed well. There were numerous folds resembling finger prints around the female genital pore. A pair of anal lobes with specified setae on them was also recognized as one of the morphological characteristics.
