Geographic distribution of the hard ticks (Acari: Ixodida: Ixodidae) of the world by countries and territories Author Guglielmone, Alberto A. 0000-0001-5430-2889 guglielmone.alberto@inta.gob.ar Author Nava, Santiago 0000-0001-7791-4239 nava.santiago@inta.gob.ar Author Robbins, Richard G. 0000-0003-2443-5271 robbinsrg@si.edu text Zootaxa 2023 2023-03-07 5251 1 1 274 http://dx.doi.org/10.11646/zootaxa.5251.1.1 journal article 235222 10.11646/zootaxa.5251.1.1 43227427-a867-4744-9e4c-2b2302524890 1175-5326 7704190 3326BF76-A2FB-4244-BA4C-D0AF81F55637 9. Amblyomma aureolatum ( Pallas, 1772 ) . Neotropical: 1) Argentina , 2) Brazil , 3) French Guiana , 4) Paraguay , 5) Uruguay ( Floch & Fauran 1958 , Aragâo & Fonseca 1961 , Nava et al. 2007 , Martins et al. 2014 , Colombo et al. 2016 b , Guglielmone et al. 2021). Amblyomma aureolatum and its synonym Amblyomma striatum , as well as Amblyomma ovale and its synonym Amblyomma fossum , were widely confused with each other until Arag ã o & Fonseca (1961) carefully defined both Amblyomma aureolatum and Amblyomma ovale . However, Guglielmone et al. (2021) regard the geographic distribution of Amblyomma aureolatum as unclear. The presence of Amblyomma aureolatum in French Guiana is based on Floch & Fauran (1958) , who published poor figures in support of their diagnosis, but who clearly separated this tick from Amblyomma ovale (under the name Amblyomma fossum ). However, Binetruy et al. (2019) were unable to confirm the presence of this tick in French Guiana , which is provisionally included within its range. Guglielmone et al. (2021) stated that records of Amblyomma aureolatum from Bolivia , Colombia , Guatemala , Panama , Suriname and Venezuela require confirmation, and these countries are provisionally excluded from the range of this tick.
