Abstract
The description of the mite species Pygmodispus (P.) bicornutus spec. nov. is presented. Females of the new scutacarid species were found to be phoret ic on the dung beetles Aphodius lividus and Ataenius sp.. The beetles were collected from two pasture areas in southeastern Brazil (Sao Paulo and Rio Grande do Sul). Other specimens of P. (P.) bicornutus spec. nov. were extra cted from a soil sample collected in Santa Cruz Island, Galapagos. It is su ggested that the new species has evolved on the South American mainland and reached the Galapagos Islands by phoretic means.
