John Gould described the white-streaked honeyeater as Ptilotis cockerelli in 1869, naming it in honour of the person—one Mr Cockerell—who shot the specimen.

[3] Alfred North erected the genus Trichodere in 1912, observing that its throat feathers were hairy in appearance, unlike any other honeyeater.

[6] Molecular analysis has shown honeyeaters to be related to the Pardalotidae (pardalotes), Acanthizidae (Australian warblers, scrubwrens, thornbills, etc.
