38. Amblyomma extraoculatum Neumann, 1899 .

Oriental: 1) Singapore ( Neumann 1899 , Barros-Battesti et al. 2007).

Barros-Battesti et al. (2007) explained that Amblyomma romitii , a Neotropical species, was thought to be a synonym of Amblyomma extraoculatum , but their study demonstrated that both species are valid. Amblyomma extraoculatum had been labelled as collected in Singapore, which was considered an incorrect locality when Amblyomma romitii was synonymized with Amblyomma extraoculatum . Barros-Battesti et al. (2007) support the validity of the original label of Amblyomma extraoculatum and treat Singapore as its type locality, but its presence there is not recognized in Kwak (2018c). Kolonin (2009) cited Amblyomma extraoculatum as a synonym of Amblyomma romitii , and Voltzit (2007) treated Amblyomma extraoculatum as a Neotropical species under the authority of Tonelli Rondelli (1939).

There is a Peruvian record of Amblyomma extraoculatum in Serra-Freire et al. (2012), but the figures presented are of another species.
