De Leon (1959) described the genus Phyllodromus with the type species, Phyllodromus leiodis De Leon, 1959, a phytoseiid mite [Acari: Mesostigmata] distributed in the state of Florida, USA. This genus remained monotypic for four decades. Moraes et al. (1997) described a second species (P. trisetatus) from the state of Bahia, Brazil. No other species has been described in, or assigned to, this genus.
During a recent revision of the taxonomy of Dendrobatidae (Amphibia: Anura), we detected that Phyllodromus De Leon is a preoccupied name created by Jiménez de la Espada (1875) for a genus of frogs (Type species: Phyllodromus pulchellum). Hence, Phyllodromus De Leon, 1959 (Acari: Phytoseiidae) represents a junior homonym of Phyllodromus Jiménez de la Espada, 1875 (Anura: Dendrobatidae).
We propose here Leonacarus nom. nov. for Phyllodromus De Leon, 1959, in application of the International Code of Zoological Nomenclature (ICZN 2000). The name refers to “the mite of Leon” acknowledging De Leon who described and recognized this taxon as a separated genus. The species currently included in Leonacarus are L. leiodis (De Leon, 1959) comb. nov., and L. trisetatus (Moraes & Melo, 1997) comb. nov.
