Seven soil samples have been collected on four islands of the Azores, in which 14 species of ptyctimous mites (Acari, Oribatida) were found. One new species Phthiracarus andreasi Niedbała sp. nov. from Faial Island is described. Four species have been recorded for the first time from the Azores. Molecular analysis showed that the differences in the sculpture patterns in Euphthiracarus excultusPérez-Iñigo, 1987 represent within-species variability. However, the length of body setae can separate two different species: Phthiracarus atlanticusPérez-Iñigo, 1987 sensu stricto and Phthiracarus falciformisMorell & Subías, 1991, despite the absence of any other morphological differences. On the basis of our morphological and molecular data, a key to species from the Azores is provided.
