(syn. Aegithalos Ϯ White-throated Tit A. niveogularis) Gr. ακανθα akantha thorn < ακη akē point; genus Parus Linnaeus, 1758, tit; "ACANTHIPARUS NIVEOGULARIS, Gould. White-throated Tit. ...It is remarkably different from every other member of the Paridæ I have seen ....it differs from them remarkably in the much greater length of its wings, and in its longer and more spine-like bill. ...I am therefore constrained to make it the type of a new genus, with the appellation of Acanthiparus, a term which has been suggested by the lengthened and pointed form of the bill" (Gould 1855).
