Linognathus setosus (von Olfers, 1816) ; Durden & Musser, 1994: 42.

Type host: Canis lupus familiaris Linnaeus, 1758 —Domestic dog.

Malaysian host: Felis catus Linnaeus, 1758 (see Remarks).

Malaysian locality: Not given (Collela et al. 2020).

Geographical distribution: Cosmopolitan ( Durden & Musser 1994; Price & Graham 1997).

Remarks: The adult male and female of L. setosus were redescribed and illustrated by Ferris (1932a). In Malaysia, Colella et al. (2020) recorded Linognathus setosus from approximately 21 out of 1152 cats examined (1.8% relative frequency), but the authors did not discuss the unusual occurrence of this louse on cats, given that L. setosus was known as a specific parasite of domestic dogs and other canines ( Durden & Musser 1994). Unlike Heterodoxus spiniger (Enderlein, 1909) , which some regarded as a general “carnivore” louse ( Colless 1959; Price & Graham 1997; Norhidayu et al. 2012), the occurrence of L. setosus from domestic cats is most likely erroneous.
