Guglielmone, Alberto A., Nava, Santiago & Robbins, Richard G., 2023, Geographic distribution of the hard ticks (Acari: Ixodida: Ixodidae) of the world by countries and territories, Zootaxa 5251 (1), pp. 1-274 : 58-59

97. Amblyomma pictum Neumann, 1906 .

Neotropical: 1) Brazil, 2) French Guiana, 3) Guyana, 4) Panama ( Fairchild et al. 1966, Keirans 1985b, Guimar ã es et al. 2001, Guglielmone et al. 2021).

Guglielmone et al. (2021) stated that authors differ in their morphological descriptions of Amblyomma pictum , and a redescription of this species’ types is needed to precisely define its taxonomy. It would also be useful to add a description of Amblyomma conspicuum , the only synonym of Amblyomma pictum ( Guglielmone & Nava 2014) , when attempting a redescription. The geographical distribution of Amblyomma pictum is treated here as provisional.

Bermúdez et al. (2018) and Dantas-Torres et al. (2019) doubt the presence of Amblyomma pictum in Panama and Brazil, respectively. There is an alleged record of this tick in French Guiana reported by Floch & Fauran (1958), but its presence there was not confirmed during the tick survey conducted by Binetruy et al. (2019). Therefore, Brazil, French Guiana, Panama and also Guyana are provisionally included within the geographic distribution of Amblyomma pictum . Argentinean records of Amblyomma pictum in Dios & Knopoff (1930, 1934) were regarded as misidentifications by Guglielmone et al. (2003), and that country is excluded from the range of this tick.
