80 Haemaphysalis punctata Canestrini & Fanzago, 1878. General. Haemaphysalis punctata, also known as The red sheep tick is mainly a tick of sheep in Europe. It has many similarities with Ixodes ricinus in its distribution but is distinct in its physical characters from Ix. ricinus, which is similarly known as The sheep tick. Differential diagnosis. As the females and males of Ha. punctata both have palp articles 2 with only a small lateral extension the mouthparts do not form the distinctly conical shape seen in some species of this genus. Haemaphysalis punctata is one of the two species of Haemaphysalis that are likely to be found on livestock in North Africa and needs to be distinguished from Haemaphysalis sulcata. The females of Ha. punctata have 11 festoons; three are enclosed by the lateral groove on each side (visible when the specimen is unfed). The females also have medium size spurs on coxae 1 to 3. Haemaphysalis sulcata females have nine festoons; only one of them being enclosed by the lateral groove, and the females’ spurs on coxae 1 to 3 are smaller than in Ha. punctata. Male Ha. punctata have short cornua and the conspicuous spur on coxa 4 is longer than in Ha. sulcata. Compared to Haemphysalis ticks Ixodes ticks are larger, darker and have longer mouthparts. Hosts. This species of tick feeds on sheep and cattle, it is also found on goats, horses, antelope and may attach to humans. Life cycle and seasonal occurrence. This species is a three-host tick. In humid climates adults may be found feeding from October to March. The life cycle can be completed in one year but usually takes three years. Disease. Haemaphysalis punctata transmits the protozoan Babesia motasi and possibly other Babesia species. It transmits the protozoans Theileria ovis and Theileria buffeli causing forms of ovine and bovine theileriosis. Habitat and distribution. Haemaphysalis punctata is adapted to a wide range of habitats. In Africa it occurs in areas with cool and humid Mediterranean climates to the steppe of North Africa. This is a tick mainly of Europe, the northern Mediterranean and eastwards in central Asia, but it also extends into North Africa. Distribution of Haemaphysalis punctata.
Haemaphysalis punctata female, dorsal in centre, ventral at upper right. 1 Palp articles 2 lateral extension is small. 2 Palp articles 2 dorsal spur is absent. 3 Palp segments 3 ventral spur is absent. 4 Coxae 1 to 3 spurs length is medium (also coxae 4 spurs are distinct). 5 Festoons number eleven. 6 Festoons enclosed by each lateral groove number three. 7 Punctation distribution is dense.
