Pedicinus eurygaster (Burmeister, 1838) *

Notwithstanding that some old and recent studies have listed “ Malaysia ” as a country where Pedicinus eurygaster is present (e.g. Durden & Musser 1994; Durden et al. 2020), there is no evidence of any actual record for P. eurygaster in this country. Considering the many reports of this louse species from many countries and old specimens labelled with now archaic geographical names, the presence of P. eurygaster in Malaysia is unconfirmed. As an example, Kellogg (1914) mentioned that specimens of Pedicinus longiceps Piaget —collected from “ Macacus cynomolgus ” (now Macaca fascicularis)—were from the “Malaysian region”. Years later, Ferris (1934) argued that these specimens were actually P. eurygaster from Natuna Island (as Natouna). However, Natuna Island is under Indonesian sovereignty, not Malaysian. More collections of lice from Malaysian macaques are needed to determine whether P. eurygaster is indeed present in Malaysia.
