Haematopinus asini (Linnaeus, 1758)

This louse species infests horses ( Equus caballus), plain zebras ( Equus burchellii) and donkeys ( Equus asinus) (Webb 1948; Durden & Musser 1994; Attia 2018; Attia et al. 2018; Gharbi et al. 2020; Sazmand et al. 2020). Due to the global geographical distribution of these equine hosts, especially horses, H. asini was considered as a cosmopolitan species (Durden & Musser 1994). None of these mammals are native to Malaysia, but they have been introduced in this country as farm or recreational animals (Bashir 1993; Abdullah and Mammalian Research Group 2013). However, there have been no records of H. asini from these hosts in Malaysia.
