Comments and Conclusions At least 283 species of Ixodidae have been recorded as parasites of humans, repre- senting 38.8% of all taxa in this family. A total of 69 species of Ixodes (Prostriata) have been recovered from people, while 214 species in all genera of the Metastriata have been found on humans, representing 27.3% and 45.0% of taxa in these groups, respectively. Numerically, the most important genera causing human parasitism are Ixodes (69 species), Amblyomma (63) and Haemaphysalis (60), but the genera with the greatest percentages of species attacking humans are Hyalomma (66.7%), Rhipicephalus (56.5%) and Dermacentor (55.0%) (Table 1). Table 2 lists all tick species that have been found on people, their distribution by zoogeographic region(s), and, for those species that occur in more than one region, Table 1 Numbers and percentages of ixodid species found feeding on humans, by genus.
