53. Amblyomma hainanense Teng, 1981 .

Oriental: 1) China (south) (Teng & Jiang 1991).

Amblyomma hainanense was treated as a synonym of Amblyomma helvolum in Kolonin (2009). This opinion was accepted by Sun et al. (2016) and probably by Chen et al. (2010), Zhang et al. (2019), Zhang Y.K. et al. (2019) and other Chinese workers, who listed Amblyomma helvolum but not Amblyomma hainanense in their studies of ticks present in China. No type comparisons were provided to support this synonymy; consequently, Amblyomma hainanense is treated as provisionally valid in Guglielmone et al. (2010b, 2020) and here, pending that comparison.
