Paraguayan tick species are listed as 1) endemic or established: Argas persicus or a sibling species, Ornithodoros hasei, O. rostratus, O. rudis, O. talaje/O. puertoricensis, Amblyomma aureolatum, A. auricularium, A. brasiliense, A. cajennense, A. calcaratum, A. coelebs, A. dissimile, A. dubitatum, A. incisum, A. longirostre, A. nodosum, A. ovale, A. pacae, A. parvum, A. pseudoconcolor, A. rotundatum, A. scutatum, A. tigrinum, A. triste, Dermacentor nitens, Haemaphysalis juxtakochi, H. leporispalustris, Ixodes loricatus, Rhipicephalus microplus, R. sanguineus; 2) probably endemic or established: Argas miniatus, A. monachus, Amblyomma argentinae, A. humerale, A. naponense, A. oblongoguttatum, A. pseudoparvum, Ixodes aragaoi/I. pararicinus, I. auritulus, I. luciae; and 3) erroneously reported from Paraguay: Ornithodoros coriaceus, Amblyomma americanum, A. maculatum.  Most Paraguayan tick collections have been made in the Chaco phytogeographic domain, in the central part of the country.  Argas persicus or a related species, A. cajennense, D. nitens, R. microplus and R. sanguineus are important parasites of domestic animals.  Ornithodoros rudis, A. aureolatum, A. brasiliense, A. cajennense, A. coelebs, A. incisum, A. ovale and A. tigrinum have been collected from humans, which is significant because A. cajennense and A. triste are potential vectors of Rickettsia rickettsii and R. parkeri, respectively.
