Significant problems attend the morphological identification of Amblyomma auricularium , as discussed in Guglielmone et al. (2020 , 2021). Some supposed redescriptions of Amblyomma auricularium reveal that different species have been included under this name, a situation that is difficult to resolve because there is no type material with which to compare bona fide specimens of Amblyomma auricularium and doubtful or misidentified ticks. Therefore, all information concerning the geographic distribution Amblyomma auricularium should be considered uncertain. Guglielmone et al. (2021) included El Salvador within the geographic distribution of Amblyomma auricularium , but Romero et al. (2021) found that this species had been confused with Amblyomma parvum . Consequently, El Salvador is excluded from the range of this tick.
