Haematopinus ludwigi Weisser, 1974

Haematopinus ludwigi Weisser, 1974: 127, figs 1–4, 6–7, 8A–F, 9II.

Haematopinus ludwigi Weisser, 1974; Durden & Musser 1994: 16.

Type host: “Wild pig from Luzon, Philippines ”, likely Sus philippensis Nehring, 1886 — Philippine warty pig (Durden & Musser 1994) .

Malaysian host: Sus barbatus Müller, 1838 .

Malaysian locality: Tinjar (Sarawak) Malaysian Borneo (Weisser 1974).

Geographical distribution: Philippines, Malaysian Borneo (Durden & Musser 1994; Price & Graham 1997).

Remarks: Weisser (1974) described and illustrated male and female adults of Haematopinus ludwigi, and the second nymphal instar without illustrations. Weisser (1974) incorrectly identified the “Wild pig from Luzon” as Sus verrucosus Boie, 1832, which only lives in the Indonesian islands of Java and Bawean. In Malaysia, the native Bornean Sus barbatus is classified as vulnerable according to the IUCN Red List (Luskin et al. 2017). Haematopinus ludwigi is considered unique as it infests two isolated species of insular wild boars, not belonging to the Sus scrofa -group usually found in the Palearctic and continental Oriental Regions (Weisser 1974).
