The first description of all juvenile stages and a redescription of the adult stages are given for the two species Rhinoseius androdon Fain and Hyland 1980 and Rhinoseius tiptoni Baker and Yunker, 1964 in the genus Rhinoseius Baker and Yunker, 1964 (Acari: Ascidae). Some idiosomal setae (especially s6) which are present in the larva are absent in the protonymph and in the following stages. A dimorphism in the deutonymphs is observed for both species which is interpreted as a sexual dimorphism. The specimens were collected from hummingbirds and from flowers visited by hummingbirds in the Choco region, Colombia. For the first time larvae of the genus Rhinoseius are observed to be phoretic on hummingbirds.
