Abstract
This paper reports on four species of free-living mites of the family Laelapidae from Tristan da Cunha and Nightingale Islands: Cosmolaelaps claviger (Berlese), Gaeolaelaps aculeifer (Canestrini), G. furcatus sp. nov., and Nidilaelaps annectans (Womersley). The new species has the unique character states of the paradactyli on pretarsi II–IV being very elongated and the pulvillar lobe well developed in shape of a fork on ambulacra II–IV. The genus Nidilaelaps Shaw is here reported for the first time from Afrotropical realm.
