The one (Trochiloecetes) is obviously an ancient inhabitant of hummingbirds, whereas the other has settled these birds rather recently. Carriker (1960) established a new genus &amp;ldquo;Trochiliphagus&amp;rdquo; for the second one. It is demonstrated that these lice belong to Ricinus de Geer, 1778, a genus with normal biting mouthparts which is widespread on Passeriformes. Trochiliphagus Carriker, 1960 is placed as a junior synonym of Ricinus and all species described till now should be named Ricinus jimenezi. Within Ricinus these hummingbird-dwelling lice are best placed in the dolichocephalus species-group. Obviously mouthparts have a high plasticity and are not good for diagnostic characters.&lt;/p&gt;
